ATORN clamping jaw with positioning pins
Application: Advantage:
The ATORN clamping jaw system with positioning pins renders complicated and ƒ Patented mechanical system that moves all pins into position at the press of
time-consuming clamping devices superfluous. the thumb (Fig. 1+2)
Execution: ƒ By pushing away the pins that are not needed (Fig. 3), almost all contact and
clamping positions can be achieved
ƒ Positioning pins are retracted and ejected mechanically ƒ Marking of clamping depth and clamping width on clamping jaw makes it
ƒ High-quality tool steel, gas-nitrided (hardened) easier to position the workpiece
ƒ Repeat accuracy ± 0.01mm ƒ A practical, fast and uncomplicated way to lock the position of workpieces in
ƒ Laser-marked clamping jaw for clamping depth and clamping width seconds, rendering complicated and timely clamping devices superfluous
