AT+ MODEL CHUCKS
The chart above refers to the replacement options for the
obsolete AT+ model of chucks. The ATSC was designed as
a replacement for this chuck – the components are not
interchangeable but the ATSC can be mounted to the
existing adapter plate from your AT+ chuck.
AT MODEL CHUCKS
The chart above refers to the replacement options for the
obsolete AT model of chucks. The BVC was designed as a
replacement for this chuck – the components are not
interchangeable, but the BVC can be mounted to the
existing adapter plate from your AT chuck.
If you currently have an AT+ with any of the numbers in
column A or B, it is replaced by a chuck in column C.
Please contact us at 1-800-228-BUCK for more
information.
If you currently have an AT with any of the numbers in
column A, B or C, it is replaced by a chuck in column D.
** Parts do not have a direct replacement but there are
alternate replacement options available that may require
you to purchase a new adapter plate. Please contact us at
1-800-228-BUCK for more information.
Chuck Selection
How do you determine what type of chuck and mounting
plate is required for the application?
What type of jaw is needed?
• The most common are the top reversible jaws. These can be
used for both I.D. or O.D. work and production work
• 2-piece jaw chucks can be adapted to soft jaws or special
top tooling
• Solid jaws are typically used for tool room applications
What size of chuck?
• For scroll chucks, do not exceed the swing diameter over the
cross slide
• For independent chucks, the next larger size may work
What accuracy and repeatability is required?
• High precision – the ATSC chucks provide .0005 TIR on
duplicate parts
• General I.D. or O.D. work – the BVC chucks provide .001 TIR on
duplicate parts
What mounting is needed?
• Determine spindle type using the spindle identifier on page 8
• Measure the major diameter of the taper and match to the chart
for the spindle type (page 8)
• For threaded spindles, you will need to measure threads per inch
How many jaws are required?
• 2-Jaw – special applications
• 3-Jaw – conventional machining
• 4-Jaw – square and offset work
• 6-Jaw – 2nd operation or thin wall parts
ATSC
APPLICATIONS:
• Precision machining
• Large quantity productions
• Higher RPM needs

Tork-Lok Arbors and Collets
TORK-LOK ARBORS AND COLLETS
The Tork-Lok arbor design answers the need for a completely versatile workholding
device. Precision ground flats on collets and arbors improve long-term accuracy and
torque transmission. Standardization of components permits interchangeability and
combination possibilities. Locates straight or tapered holes on true center.
Safety Stops

Precision Mated
Flats on Collet
Installation and Operating Instructions
Safety Stops
The expansion safety stop is fixed in all styles and requires no adjustment. The
contraction or loading position safety stop is adjusted to suit the part being chucked.
Precision Mated Flats on Both
Expander and Arbor Body
Preload
All collets are manufactured to include a preload. Collets should not be adjusted below
the range minimum for that collet. Preloads are .008 average on sizes from .500-.874
and .015 from .875-4.467.
Chip Clearance
Special Work Stop Consideration:
Combination Work Stop and Retaining Sleeve: Restricor Type Work Stops are necessary
for parts whose gripping length is shorter than the collet. Since the Tork-Lok collet
expands at both ends, a retaining sleeve is needed to prevent the free end of the collet
from over expanding; a Restrictor Expander is used to reduce the expansion safety stop,
preventing collet breakage (in case arbor is operated without a part in position).
Notes:
• All Tork-Lok arbor applications require a part stop
• If Restrictor Type Stop is used, a special Restricor Expander is required
• Contact us at 1-800-228-BUCK for more information

Drawbar should be in forward or push position. Adjust forward
expander with Allen wrench until part is a slip fit on the collet. Collet
flats both ends must mate.
Collet Changing
Drawbar should be in forward positions. Using Allen wrench, remove
forward expander. Collet and rubber sleeve can then be removed. Wash
parts in clean solvent. Lightly grease expander flats in contact. Install
forward expander. Adjust according to instructions outlined above.

To Interchange Assemblies
Apply 70 psi, remove mounting screws, turn arbor assembly
counterclockwise until drawbar disengages from piston assembly.
To mount assembly, apply 70 psi. Be sure threads on drawbar are
clean and oiled. Turn arbor assembly clockwise until face contacts
cylinder. Back off to align tapped holes in cylinder. Insert screws and
adjust according to instructions outlined above.
