Chapter 1
Tool Regrinding
The importance of Tool Regrinding
Regular regrinding of tools is essential to achieve consistent quality holes.
Regrinding regularly by small amounts ensures that the machine and tooling last
longer. The importance of regrinding at the correct time is illustrated in Figure 2.
Indicators That a Tool Needs Regrinding
There are no hard and fast rules for the number of hits a tool can achieve before
regrinding becomes necessary - it depends upon size and shape of tool as well as
material type and thickness.
There are three key indicators that a tool needs regrinding:
•
Monitor the tool cutting edge. It is recommended that tools be re-sharpened
when the cutting edges are worn to .004" (0.1mm) radius. (See Figure 1).
Figure 1: Regrind tools when .004"
(0.1mm) radius develops on cutting
edge
If radius is
.004"
(0.1mm) or
over,
regrind
tool
•
•
Monitor the quality of the holes. Are there excessive burrs? (See Figure 3).
Monitor the punching noise. If the punch press is making more noise when
punching with a particular tool than it normally does, the tools cutting edge
may be dull.

If punches are reground regularly, you have the advantage of the quality and precision of the holes remaining constant in addition to fewer stripping
problems. With Optima coated punches, regular regrinds are just as important in order to get the maximum life from the tool - more than 7 times more.
GOOD REGRINDING PRACTICE - Regrinding small amounts frequently.

2nd REGRIND
120,000
WITH REGULAR REGRINDING, the tool is sharpened every time a .010"
(0.25mm) radius develops on the cutting edge. .010" (0.25mm) is removed from the tool to restore sharpness, and since the edge breaks
down more slowly, the tool lasts longer.
Note: The number of hits shown on the chart below cannot be guaranteed,
and is shown as a guide only. It depends on material type and thickness
being punched, and on the machines' alignment. A low number of hits has
been shown to highlight how much can be saved. If your tool takes more
hits to develop a .010" (0.25mm) radius on the cutting edge, even greater
savings will be made.
WITHOUT REGULAR REGRINDING, the punching edge of the tool
breaks down more quickly. A .040" (1mm) radius can develop in
less than 80,000 hits. This means that .040" (1mm) has to be
reground from the tool to restore sharpness.

Methods for Regrinding
Several methods exist for the regrinding of tools. Many customers use Swing Grinders (grinding machines developed for tool sharpening only), and some customers also
utilize a conventional surface grinding machine with special fixtures designed to hold
the tooling.
Regrind Rules
The following factors should be considered when regrinding tools.
•
•
•
•
•
•
•
Removal of between .004" (0.1mm) and .010" (0.25mm) should return the tool to
proper sharpness.
The grinding wheel should be dressed to present a new, clean flat surface.
Wilson Tool suggests the use of an open, coarse, soft bond wheel.
For example, a Norton SGB46KVX.
Light, frequent passes should be taken, vertically no more than .0005" (0.01mm)
per pass while moving horizontally on the punch or die face. Removal of more
material per pass may cause the metal to burn resulting in surface cracking. These
heat checks will cause the punch tip edges to break down quicker than usual,
resulting in a need for more frequent regrinds and reducing tool life.
The tool must ALWAYS be flooded with coolant while grinding.
To minimise vibration and chatter, the punches or dies should be firmly clamped in
suitable fixtures. Fixtures should be quick-change and capable of indexing in order
to grind shear angles on punches.
Sharpening OptimaTM TiCN coated punches will not affect performance. This is
discussed later in the manual.

•
•
When using OptimaTM TiCN coated punches, (which have longer life), the
sharpness of the die must be checked on a regular basis.
Maximum regrind life for the tools should be checked before regrinding.
Exceeding maximum life may lead to tool and machine damage.
WARNING!
Regrind life of tooling is dependant on the thickness of the material to be punched.
An Example of Tool Regrinding
The following section illustrates the processes involved in tool regrinding. The use of a
conventional surface grinding machine with dedicated fixtures (as produced by Wilson
Tool International) has been chosen as the selected procedure.
Sharpening Procedure
•
Use a surface grinder with a shut height of no less than 9" (230mm)
(as illustrated in Figure 4).

Use an open, coarse grinding wheel (e.g. Norton SGB46KVX or equivalent)
2.
Install the tool in the tool adapter (as illustrated in Figure 6).
3.
Secure the tool in the holder by tightening screws (A) or (B), (as illustrated in
Figure 6).
4.
Install the holder in the grinding fixture ensuring the tip shape is set at a 90° angle
to the grinding wheel (as illustrated in Figure 4). Tighten screw (C) (as illustrated in
Figure 5).
5.
For shear grinding, loosen screw (D), remove plug (E) and set the required shear
angle (as taken from Figure 7: Shear angle table).

9.
For a 0° angle, leave plug (E) in place.
Tighten screw (D), and you are ready to grind. Grind tools from the outside edge
towards the center. The tool should be flooded with coolant at all times.
Frequent passes of no more than .0005" (0.013mm) should be taken.
When regrinding punches with rooftop shear, after regrinding the first angled
face, the tool holder should be rotated 180° to grind the second face.

Calculating Maximum Regrind Life
The amount of the punch or die which can be reground (grind life) is dependent upon
the punch straight before radius, the material thickness, the stripper thickness and
the die penetration for the punch press. The relationship of these factors is shown in
the formula below and in Figure 8.

Chapter 3
Maintaining tool life
It is important for the customer to achieve maximum life out of tooling to reduce costs.
Tool life is dependant upon the following factors:
•
•
•
•
•
•
•
The use of tool coatings
Sheet lubrication
The use of shims
Style of tooling (i.e. Old Style or Series 80, 80 Plus or 90)
Die clearance
Turret alignment
Type and thickness of material to be punched
Using Optima Coating to increase tool life
TM
For many years, Wilson Tool has supplied TiN coated punches to increase tool life.
However, the higher punching speeds of the newer punch presses have led to a demand
for higher performing, longer lasting tooling. To meet this need, Wilson Tool has
introduced OptimaTM, a new TiCN (titanium carbo-nitride) coating which offers superior
performance to conventional TiN coated tooling.
Using our own state-of-the-art in-house facilities, Wilson engineers spent two years and
over one million dollars developing OptimaTM The results of the testing* are shown in
Figures 12 to 15.
*Tests were performed under laboratory conditions at Wilson Tool International using correct die clearances, with all tools properly sharpened, and all turret stations properly aligned. Actual results may vary
depending upon the application.

Some of the benefits associated with
OptimaTM coating include:
•
•
•
•
•
•
•
•
•
Longer tool life
Increased wear resistance
More hits between tool regrinds
Reduced material adhesion to punch surface (galling)
Reduced slug pulling
Reduced corner breakdown
Improved special tooling performance
Lower overall tooling costs
In-house coating facilities allow us to deliver faster and maintain total
quality control
OptimaTM coated punches are available for all Thick and Thin Turret tooling styles.
The Tool coating myth
There is a myth that the benefits offered by OptimaTM coated punches are lost after the
punch has been sharpened. This is not true. Even after the first regrind (when the
coating is removed from the front face) the life remains excellent. This is due to the
hard coating staying on the sides of the punch where the work is done and the protection is needed. (See Figure 12).
Achieving maximum tool life with sheet
lubrication
Wilson tool advises the use of sheet lubrication wherever possible to extend tool life.

Achieving maximum tool life with tool
lubrication
Proper lubrication of tools helps to reduce wear. Wilson Tool recommends the use of a
graphite or moly based grease (or 80, 90, or 150 wt oil) on the inside of the tool, between
the guide and the punch, and a light machine oil on the outside of the tool, between the
guide and the turret.
Lubricating Series 80 Plus and Series 90
Punches
Wilson large station guide assemblies are equipped with an internal lubrication system.
At the beginning of each shift, using a hand pump oiler, approximately two squirts of
80/90 wt oil or ISO 100 oil (a heavy gear oil) should be applied down the centre hole.
The outside of the tool, between the guide and turret bore, should be lubricated using
either the same oil or a lighter oil. Daily use is recommended.
The WLS tool lubrication system.
Wilson Lubrication System tooling has been developed to suit machines with the automatic tool lubrication facility. WLS Series 90 tooling is engineered with an internal /
external lubrication system that provides lubrication between the punch body and the
guide, as well as between the guide and the turret, on every stroke. This means that
the tooling and turret are automatically lubricated by the machine.
Extending tool life with the use of shims
Shims can be used to extend the life of dies for all stations, and also to extend the life
of "old style" punches in all stations. Shims are used after regrinding the punch or die.
The die shim maintains correct die penetration by the punch.
It is recommended that only hardened, precision shims manufactured from a suitable
shim steel be used. Failure to use quality shims will result in shim warpage which can
cause misaligned tools, decreased tool life and die shoe damage.
Warning! Shims should only be used with old style punches - never shim Series
80, Series 80 Plus or Series 90 punches.
Full instructions for shimming old style punches are given in Appendix
2: Tool Setting and Sharpening Instructions.

Shimming Old Style A Station punches
Disassemble the tool. Place the punch shims between the Spring Retainer Clips and
the Spring Retainer. Reassemble the tool.
Shimming Old Style B Station punches on Thick
Turret, Thin Turret and Strippit® machines.
After disassembling the tool, place shims down the shank of the punch until it rests on
the punch shoulder.
Adjusting B Station and 5/8" Drop-In punches
Loosen the set screw in the punch head and rotate the punch head to move the punch
up or down as required. When the tool has been adjusted to the correct length, the set
screw should be tightened against one of the verticle grooves in the punch threads.
Shimming T hick Tur ret, Thin Tur ret and
Strippit® old Style C, D, E & F Station punches
Following the removal of the punch from the guide assembly, a shim should be placed
on top of the punch, with the slot aligned with the key pin. The punch and shim should
be placed carefully into the guide for assembly, with extra care taken not to disturb the
shim alignment. The tools should always be lubricated before reassembly.
The problem of over shimming old style
punches
Excess shimming of old style punches causes loss of key location. If too many shims
are used, the punch driver key no longer engages within the punch slot. This is shown
in Figure 16.

An alternative to shimming - The Series 80,
Series 80 Plus & Series 90 Tooling Systems.
In the 1980s, Wilson Tool engineers developed an alternative to Old Style large station
tooling - the Series 80 concept. This style of tool has been replaced in the 1990s by
Series 80 Plus and Series 90 tooling, with both systems refining the tool length adjustment ideas of the Series 80 original.
Series 80 Plus is available in large stations for Thick Turret, Thin Turret and Strippit®
machines. Series 90 is available in small and large stations for the same machines.
Series 90 tooling is identical to Series 80 Plus tooling in every respect apart from the
addition of a push-turn-lift stripper retention system.
Series 80 Plus and Series 90 offer simple, click adjustment for punch length, with extended regrind life in all ranges. They also offer the following advantages over conventional old style tooling:
•
•
•
•
•
•
•
Increased punch grind life - up to three times more than old style
Simple turn and click punch length adjustment
Quick set -up
Reduced tooling costs
More bearing surface for increased stability
Simple fingertip adjustment - no tools needed
No need for length check

Users of Old Style Thick Turret tooling experience the aggravation of manual shimming, limited grind life, and lengthy set-up times. This leads to high operating costs
and low productivity.
To ease the common problems experienced with Old Style Thick Turret punch assemblies, Wilson Tool International has developed a new tooling system - Concept 2. The
Concept 2 Large Station assemblies accept standard Thick Turret Old Style tooling,
increasing grind life and reducing set-up times.
Some of the features of Concept 2 include:
•

Achieving maximum tool life by using
suitable die clearance
Selection of die clearance should be based upon the type and thickness of material to be
punched. Incorrect selection of die clearance can cause the following problems:
If clearance is too small, tool wear will increase and galling may result.
If clearance is too big, slug pulling may result including excessive burrs.
Clearance should be selected using the clearance table shown in Figure 17.

Note:
Wilson Tool recommends the Best % total clearance for optimum performance. However, as material thickness increases approaching .156" (4mm), the maximum die
clearance percentage should be selected from the table above rather than the best die
clearance percentage.

Maintaining tool life by regularly checking
turret alignment
Turret alignment is a critical procedure which can help prevent problems such as poor
tool life, unacceptable part quality, and turret wear. Wilson Tool recommends regular
checks for station alignment on random stations within the turret.
For more information regarding the procedure for turret alignment, and to obtain suitable tools, contact the Sales Desk or your Sales Representative.
The turret keys must be checked on a regular basis.
Worn turret keys can lead to excessive tool wear and rats tails.

Tooling Information
This section contains information to help prevent tooling problems, and also to aid the
ordering and day-to-day running of Wilson Tool Turret Tooling.
Selection of die type
The three different die styles as offered by Wilson Tool are illustrated in Figure 18.
Figure 18: Die styles
Positive Taper
This is the best style of die for punching holes of less than .236" (6mm) diameter in mild
steel and stainless steel, or less than .472" (12mm) diameter in aluminum.
However, use of this style of die can result in slug pulling.
Negative Taper
Although the taper is only .0005" (0.01mm), this is enough to help squeeze and hold
the slug as it is pushed down into the die land, thus helping to prevent slug pulling.
Negative taper is not recommended for punching aluminum or plastic because of slug
packing.
30

Slughugger Dies
This is the only guaranteed method of stopping slug pulling and is especially
recommended for use with modern punch presses due to the high punching speed.
The high speed of todays punch presses has increased the problem of slug pulling. The
quicker punching speeds increase the problem of a vacuum forming between the punch
and slug, pulling the slug out of the die as the punch retracts. To resolve this problem,
Slughugger dies have been developed.
A Wilson Tool innovation, Slughugger dies have specially designed bumps on the inside
of the die land which hug the slug and ensure that it stays within the die. This style of die
is individually designed with each order to suit the particular material type and thickness to
be punched.
Slughugger dies also offer the advantage of stopping slugs spinning within the die. This
principle is shown in Figure 19. Spinning slugs can cause the sheet to be pulled from the
clamps causing sheet and tool damage.

Punch Shear
Although shears are usually used to reduce punching force, a small amount of shear on
punches can also greatly reduce the noise level when punching most materials, especially stainless steel.
For reducing punching force when punching thick materials, shear on the punch tip or
die surface is of little value unless the shear depth is greater than or equal to half the
material thickness.
Figure 20 shows the shear types offered by Wilson Tool.
Figure 20: Shear Types
Each shear has benefits and limitations which make it more suitable for certain applications. These features are highlighted in Figure 21.
32
Thick Turret
Thin Turret
Strippit ®
Shear Table
Shear Type
Benefit
Limitation
Rooftop shear
Best shear for minimizing
punching force in thick
materials.
Nibbling must be done with
75% of bite or excessive
side loading will result
Concave or
double concave
shear
Best shear for partial hits.
This shear forms a lock
against the sheet which
resists punch deflection.
Because of inverted
stresses, a narrow punch
can split with high punching
force operations.
Inverted rooftop
shear
Also a good shear for
nibbling because of
inverted stresses.
Easier to sharpen than
concave shear.
More susceptible to breakage because of a sharp
focal point for stresses. Do
not use narrow punches on
heavy materials.
Double valley
shear
Best shear for nibbling
when the shape is long
and narrow.
Because of inverted
stresses, the punch can
break when punching at
high tonnages.
J.K. Shear
A special type of shear
developed to punch and
easily strip out of heavy or
high strength materials.
Maximum punch tip size is
1.000" (25.4mm).
Caution: Increases tonnage.
Figure 21: Benefits and limitations of shear types
Stripper Clearance Types
Wilson Tool offers the following three stripper clearance types:
Closed Round Stripper
This style of guide or stripper is used when punching heavy plate with an additional
punch tip length, and to eliminate scale build-up within the guide. It is also a good
choice for use in Drop-In guide assemblies for quick change capabilities. Some care is
necessary when punching thin or soft materials to avoid marking or bending the
material.
Fitted Shaped Stripper
This style of guide or stripper is the Wilson Tool standard for individual punch and
guide assemblies. It gives the support needed around the punch to eliminate sheet
marking while still preventing scale building up within the guide.
Thick Turret
Thin Turret
Strippit ®
33
Slip Fit Shaped Stripper
This style of guide or stripper is used when material deformation is a problem, as in punching
foil gauge materials. It can also be used for some nibbling operations. There are associated problems with galling and material build-up in the guide, so this style of stripper is
only recommended for special applications.
The three styles of stripper are illustrated in Figure 22.
Figure 22: Stripper clearance styles
Calculating Punching Force
When punching holes with a large perimeter in heavy gauge materials, exceeding the
recommended punching force (tonnage) could damage the machine or tooling. Therefore, Wilson Tool recommends the calculation of punching force whenever large tools
are used in thicker materials. This is done using the following formulae:
Punching Force (Tons) = Total land distance (L)(shape perimeter) x
Material Thickness(T) x 25 x Material Multiplication factor (F) x Shear
Factor (S)
Punching Force (kn)= Total land distance (L)(shape perimeter) x Material Thickness(T) x .345 x Material Multiplication factor (F) x Shear
Factor (S)
The figures for (T), (L), (F) and (S) can be determined from the following four tables
(Figures 23, 24, 25 & 26).

Interchangeability of Series 90 Thick Turret
Components
Certain components within Series 90 Standard, ABS and WLS assemblies are interchangeable with each other. Components are designed to be standard between the three
ranges of tooling wherever possible to make the changeover from standard tooling to
WLS or ABS tooling as easy as possible. However, using incorrect components within
assemblies can reduce the tooling life, as well as damaging the tooling and machine.
To reduce the risk of damage, Figures 28, 29 and 30 show how to identify if component
parts are standard, WLS or ABS, and Figures 31, 32 and 33 show which components can
be interchanged with each other between the three styles of assembly.

Recommendations for punching heavy gauge
materials (.158"/4mm Plus)
Wilson Tool suggests the following measures for punching thicker gauge materials.
The problems associated with punching stronger and thicker materials can be avoided
with a little care and planning.
General Suggestions for all Tooling Ranges
•
Die clearance should be adjusted to 20-25% of the material thickness.
•
The sheet, punch, guide and turret should be lubricated.
•
Extra back taper should be used on the punch tip.
•
Tooling should be frequently inspected for wear.
•
Punch tip dimensions should be larger than the material thickness.
•
.020" (0.5mm) radius corners should be used on all punches with sharp
corners.
•
The maximum regrind amount should always be checked before regrinding.
This can be found in Chapter 1: Tool Regrinding.

Suggestions for Thick Turret tooling
A Station
•
•
The use of a standard A Station punch assembly is not recommended due to
probable total collapse of the spring.
Heavy Duty A Station punch assemblies should be used at all times.
Warning! Maximum material thickness is .250" (6.35mm) with this style
of tool.
B Station
•
•
•
•
•
Warning! Maximum material thickness is .315" (8.0mm)
(although this can be increased with the use of a closed round stripper
with extended clearance).
B Station Heavy Duty punch assemblies are recommended.
Punches should have extra straight before radius.
Try bridge hits instead of nibbling.
Try JK shear on punches (full hits only).
C Station
•
•
•
•
Warning! Maximum material thickness is .500" (12.7mm).
Special heavy duty style punches should be used in Series 80, Series 80 Plus
or Series 90 assemblies. Special strippers should be used with this style of
punch.
o
Special spring packs should be used in Series 80 (Cat N 05121), Series 80
o
Plus and Series 90 assemblies (Cat N 05245 for both styles).
Care should be taken not to exceed machine punching force (tonnage) when
punching large shapes in heavy gauge material. Punching force can be
calculated using the formula given in Chapter 4: Tooling Information.
D Station
•
•
•
•
Warning! Maximum material thickness is .375" (9.5mm).
Special spring packs should be used in Series 80 (Cat No 05160), Series 80
Plus and Series 90 assemblies (Cat No 05174 for both styles).
Rooftop shear depth should not be more than .125" (3.2mm).

Recommendations for punching non-metallic
or plastic materials
As industry has changed, there has been more call to punch a variety of materials such as
plastics or other non-metals. The following recommendations are given to reduce problems when punching these often difficult materials:
•
•
•
•
•
•
•
•
Punches and dies should be extremely sharp.
Die clearances should be reduced to 5% - 8% of material thickness.
Positive taper dies should be used.
Support should be given to foil gauge materials with a sheet of single laminate
cardboard. This allows the material to ride over both the turret and the table.
The machine should be run in slow cycle, watching at all times for failure to strip.
If the stripper marks the sheet, Zip-Mar should be applied to the bottom of the
guide and a light spring pack should be used.
Hard plastics should be lubricated before punching.
Abrasive or fibre reinforced materials such as Plexiglas or laminated epoxy glass
cause additional punch wear. OptimaTM TiCN coated punches can help to
reduce tool wear.

Recommendations for punching soft or thin
materials
When punching thin, soft materials (such as aluminum or brass), witness marks may be
left on the material from either the die or the guide. The following recommendations should
be followed if this should happen:
•
•
•
The die and guide should be checked for sharp particles, irregularities and
material build up.
If marks persist, Zip-Mar patches should be attached to the bottom of the guide
assembly. Alternatively, masking tape can be applied to the guide and die.
If problems still persist, special light duty springs or spring packs should be used.
This reduces spring pressure.

Chapter 9
Recommendations for the use of forming
tools
•
Machine stroke length varies. This means that a tool properly set and working
on one machine may be over or under set for another. Tools should always be
reset on their shortest setting.
•
The tool should always bottom out to achieve the best form. This is achieved by
starting with the shortest setting, adjusting the tool by approximately .004" (0.1mm)
at a time and taking sample hits. The adjustment is complete when faint grind
lines appear on the sample part.
Warning! Overstroking will cause tool and machine damage.
•
The tool length should not be altered by more than .005" (0.12mm) per adjustment. Over adjustment will cause the tool to overstroke, fatigue and fail.
Easy Set punch heads can be used on small station tooling, and Series 90
adjustable holders can be used on large station form tools to make adjustments
in small, known increments.
•
Sheet bowing or marring can occur if the material is formed into the stripper
plate. Excessive stripping pressure can be corrected with the use of a light
spring or light spring pack.
•
Ball rolling dies should be used either side of the forming die within the turret.
The lower turret must always be full of dies, but use of forming or standard dies
in the stations next to the forming die will result in sheet distortion.
•
Forming should always be done as far away from the clamps as possible.
•
Forming should always be the final operation on the sheet wherever possible.
This eliminates the possibility of a collision between a standard punch assembly
and an existing form on the sheet.
•
Lubrication of the sheet aids stripping and prevents galling.
•
Slughugger dies should be used to prevent slug pulling. Slugs left on the sheet
cause tool damage.
•
Many forming tools have positive stops, which must be retained after regrinding
to maintain form quality. Instructions are provided for all forming tools which
require regrinding.
•
Relieved slitting assemblies can be used to slit close to forms on the sheet.
•
Forming tools with built in stripping require additional time to strip. Therefore,
form tools should be run at a slower punching rate.

Chapter 10
Recommendations for the use of Cluster
Tools
General suggestions
•
Punched holes should not be re-entered by the cluster punches. Doing so causes
shaving of the holes and dangerous side loading of the tool.
•
Sheet lubrication is important.
•
Tooling should be regularly checked for sharpness.
Minimising sheet distortion
In punching some perforated patterns on a punch press, material deformation can be a
problem. Stresses in the sheet caused by punching large numbers of holes can cause
the material to warp. The following suggestions can help to minimize sheet distortion:
•
Punches and dies should be kept sharp, and die clearance should be selected
to suit the type and thickness of the material to be punched. Dull tooling and too
much clearance increase the coining effect of each hit.
•
Lubrication should be used on both the top and bottom of the sheet. The oil
helps to keep the cutting edges of both the punch and die sharp, as well as
aiding stripping.
•
The pattern should be punched either from the outside of the sheet inwards, or
from the inside of the sheet outwards. Various materials behave differently.
•
The punching pattern should be staggered, alternating rows and taking several
passes to complete the pattern. In some extreme cases, it may be necessary to
flip the sheet on every other pass to equalise the warping effect.
•
Build-up should be frequently removed from the tools.
•
The lower coefficient of friction of OptimaTM TiCN coated tooling helps to prevent
warping.

53
Tool limitations
•
Round holes must have a web between holes of .118" (3mm) or 2 times material
thickness, whichever is greater.
•
Long and narrow shapes must have a web between holes:
•
Up to .500" (12.7mm) length - .125" (3.2mm) or 2 times material thickness,
whichever is greater.
•
.500" (12.71mm) to 1.000" (25.4mm) length - .185" (4.7mm) or 2 times material
•
1.001" (25.41mm) to 2.000" (50.8mm) length - .250" (6.35mm) or 2 times
material thickness, whichever is greater.
•
2.001" (50.81mm) length and above - .315" (8.0mm) or 2 times material
Tool maintenance
•
Punches should always be as sharp as or sharper than the die.
•
When sharpening the punches, the punch inserts must be supported. If not
secured, the vibrations caused by regrinding will break the inserts. Vibration
can be reduced by wrapping the inserts in rubber bands or with the use of a
punched plastic sheet.
•
When using OptimaTM TiCN coated punches, (which have longer life), the
sharpness of the die must be checked on a regular basis.

Troubleshooting
The most common reasons for punching operation stoppages on punch presses are tooling problems. Included within this section is a table of the most common tooling problems,
along with possible solutions. This enables the user of Wilson Tooling to identify and
prevent possible problems. Wilson Tool technical experts are also always available to
help with tooling problems.
Basic points to remember:
•
Die clearance should be selected to suit the type and thickness of material to be
punched.
•
Slughugger dies should be used wherever possible to eliminate slug pulling.
•
Tools should be regularly reground.
•
Tools should be regularly cleaned and lubricated.
•
Nibbling causes side loading on the punch, causing additional wear.
This principle is illustrated (exaggerated) in Figure 34. Optima TiCN coating can
be especially useful in nibbling operations.
•
Possible tooling problems should be identified using the troubleshooting tables,
and eliminated.
•
The Wilson Tool Sales Desk members are all technically trained tooling experts,
and can be called at any time to help solve tooling problems.

Chapter 12 Possible causes of tool
breakage - standards
Most tool breakages can be attributed to the same few reasons. This section highlights
the most common causes of standard tool breakage.
Thick Turret Tooling; Punch body breakage:
C Station
•
Broken shank caused by:
•
•
•
•
Overtightened bolt (Wilson Tool recommend 50ft.lbs (67.7Nm) of torque to
tighten bolt)
Using a well used or stretched bolt (causes the top of the shank to break off)
Using too many shims on a non-Series 80, 80 Plus or 90 tool holder
(breakage caused by too little thread engagement
Broken flange caused by
•
•
•
Dowel pin not seated properly in keyway of punch holder
Material slivers or chips between the punch and punch holder
The use of poor quality shims
D Station
•
•
•
•
•
Overtightened bolt (Wilson Tool recommend 50ft.lbs (67.7Nm) of torque to
tighten bolt)
•
•
•
Material slithers or chips between the punch and punch holder
Punch tip breakage
Use of a punch which is smaller in diameter or width to the thickness of the material will
probably cause the tip to break, no matter what the range. It is recommended that
Stubby style punches are used for these operations. Stubby punches use a very small
length of punch tip of the desired hole size, thus supplying the additional strength and
rigidity to punch thicker materials than the tip size.
Die breakage
•
•
•
•
•
•
•
•
Slughugger or negative taper on long, narrow shapes, or small rounds
(positive taper recommended)
Dull tooling (punch & die should be checked for sharpness)
Poor turret alignment
Incorrect die clearance
Slug pulling
Punch deflection (side loading of punched caused by nibbling on small pitch or
edge trimming with punch)
Embedded chips or slivers of material in die or die shoe causing the die to not
sit flush
Maximum punching force or material thickness for station has been exceeded.

Possible causes of tool breakage - specials
Most tool breakages can be attributed to the same few reasons. This section highlights
the most common causes of special tool breakage.
Piercing tools
Triangles, diamonds or inverted diamonds
Sharp points on angles less than 60° (radius corners of ½ the material thickness are
recommended)
Shapes with internal tabs
•
•
Internal tab is deeper than it is wide
The width of the tab is smaller than the recommended minimum for the material
type and thickness. Recommended parameters are that the width of the tab
should be at least the material thickness for aluminium, 1.5 times the material for
mild steel and 2 times the material for stainless steel
Narrow shapes
•
The width of the shape is smaller than the recommended minimum for the
material type and thickness. Recommended parameters are that the shape
width should be at least the material thickness for aluminium, 1.5 times the
material for mild steel and 2 times the material for stainless steel
Cluster tools
Inser t breakage
•
•
•
•
•
•
•
•
The punching force is too large for the die
Slugs on the sheet caused by slug pulling
Improper die clearance for the type and material to be punched
Dull cutting edges on the inserts
Improper sharpening (causing burnt inserts or stresses caused by vibration)
Punched holes are re-entered to complete the pattern
Operator error
Die breakage (webs breaking)

Problem Solving Checklist for Tool Failure
Following is the list of questions Wilson Tool asks when trying to establish why a tool has
failed. Answers to these questions often give clues to possible problems.
Piercing Tools
•
•
•
•
•
What type and thickness of material was used?
Has the turret alignment been checked on the machine?
Have the tools been sharpened? Properly?
Was anything unusual noticed before failure?
Was there much sheet distortion?
Forming Tools
•
•
•
•
•
•
•
•
•
•
What type and thickness of material was used? Was it the material the tool
was designed for?
Has the turret alignment been checked on the machine?
Is the tool length set properly? Does the tool bottom out?
Is there a post delay in the program to allow the tool to strip?
Are the forms close to the clamps?
Is there any noticeable damage to the tool (e.g. burrs, nicks or chips)?
Has the tool been sharpened? Properly?
Was the correct size and shape pre-punch used?
Was the spring pressure in the upper unit reduced (if required)?
How often is general maintenance carried out on the tool?
