Special Applications
Choose the Optimum Robot for Your Application
WITTMANN robots stand out through their complete flexibility in their configuration
and suitability for special applications.
W733SO
Two robots mounted on one horizontal axis to share the work space in a time
critical application or to use a common palletizing area.

of the injection molding machine
- Robots can be delivered with an external control cabinet to connect
extensive amounts of peripheral inputs and outputs
W733SO
Robots for Fastest Removal Times
W721UHS
The ultra high speed robot series has been developed to achieve the fastest part
removal times. Depending on the stroke distance and motion, the time for in/out
movements is just 0.3–0.5 s. This is possible using highly dynamic servo modules
and motors with high performance density while at the same time minimizing the
moving masses of the rotational axes that need to be moved. This guarantees the
direct transfer of forces as well as minimizing the moving masses. In order to achieve
these short removal times constantly over the long term, the vertical axis is activated
directly over a planetary gear box engaging with a generously dimensioned tooth belt.
For mechanical absorption of the high acceleration and deceleration forces of 6g, the
vertical axis is designed with an extremely torsion stable kick stroke which is internally
reinforced with ribs. The vertical axis itself is an aluminum profile, which by means of
Finite Element calculations is designed for the lightest weight and highest stiffness.
Advantages:
Highest productivity of the injection molding machine with
the shortest cycle
Minimizing all moving masses for the highest acceleration
and deceleration

Z-axis (horizontal stroke)
All larger robots including the W721
model are driven in the Z-axis via rack
and pinion with built in lubrication
chamber for high speeds and long life
operation. The rack and pinion drive guarantees precise positioning also with long
strokes, avoiding the flexibility of long belts.
Rugged Steel Beam
Precision machined for perfect alignment
of rails and rack.
Kick Stroke Beam
A large aluminum extrusion provides a stiff,
vibration free foundation for the vertical arm.
The reduced moveable mass allows high
acceleration and deceleration for extremely
short cycle times. The bearings for horizontal
stroke and kick stroke are positioned in the
main carriage next to each other to provide
optimum stiffness and minimum vibration for
high speed operation, allowing precise insertion
and removal.

linear bearings with lubrication chains.
These are the latest technology bearings
providing lubrication intervals up to one
year! (Depending upon robot cycle and
operating conditions).
Standard C-axis
C-axis rotation for placing parts. Compact
design for minimum mold opening. Pneumatically operated rack and pinion drive for
high and constant torque during rotation.
- B-axis motor driven 0–270° rotation for
removal from fixed or alternatively movable platen
side and for flexible placing of parts in different
orientation. Programming through teach pendant.
- Six degrees of freedom and motion control
available with optional A-/ B- or C-axis wrists for
secondary requirements.
Touch Screen Control R7.2
R7.2 Touch Screen
All servo driven robots are equipped as standard with the R7.2 TeachBox touch
screen control with graphic operating interface. The direct selection of all functions on the touch screen enables easy and quick creation of programs. To avoid
program changes the TeachBox can be unplugged from the emergency stop block
that contains the main operating functions of the robot. Teach programs can be
either saved via the integrated USB-port – on the memory stick provided – or on
an integrated flash card memory.
Advantages:
Shortest training time for personnel
Free programming of every robot operation
Infinite diagnostic possibilities for the robot functions
Integrated observation of maintenance intervals
Different programming levels for the respective user profile
Text Editor R7.2
Graphic Editor R7.2
Ideal for programming complex
working cycles, for numerous
pieces of auxiliary equipment as
the operator can program/edit
any sequence via the menu navigation. The editor does not need
command codes, the designated Text Editor R7.2
function is executed directly at the
robot and is transferred via a keystroke into the program.
The naming of the peripheral inputs and outputs, cylinders, grippers, and vacuum cycles
facilitates the readability and allows for a clearly arranged program structure. Complete
flexibility is possible when creating programs.
For standard applications the desired operating sequence
can be created graphically on the display. After assigning
the numeric positions to the program, it can then be
instantly placed into Automatic mode – creating an entire
program in only a few minutes.
Only minimal initial training of the personnel is necessary.
