Scotchman does not recommend this unit for all general punching applications. However, using this
specially designed "Non Deform" stripper unit does offer a significant advantage over a standard
stripper arrangement in reducing distortion when punching a confined pattern or series of holes in flat
bar or plate.
7.13 URETHANE STRIPPER
The action of this unit will minimize distortion in the work piece and in many cases eliminate costly
correction and straightening processes. Of course, there is a limit how much material can be removed in
a confined area without causing some deformation. Contact your dealer or Scotchman for advice.
Combining this unit with a linear feed repetitive stop system for punching a series of holes in flat bar will
significantly increase productivity.
Because of the action of this type of unit, particular attention must be paid when setting the stroke length.
The stripper unit moves in conjunction with the punch and extra care must be taken by the operator.
(Refer to the setting and operating instructions in this section.)
The maximum thickness which can be punched using this unit is 1" (25mm) in steel with a rated tensile
strength of 65,000 lbs. psi.
►
NOTE: THIS STRIPPER ONLY WORKS WITH #40 TOOLING. THE MAXIMUM HOLE
SIZES THAT CAN BE PUNCHED ARE 1-1/4 (31mm) ROUND AND OVAL AND
3/4 (19mm) SQUARE.
