Collet HSH series

For HSC workpiece machining the clamping forces accord ing to DIN 69893 are frequently no longer sufficient. The idea to create an extremely rigid connection between the tool and spindle by placing the clamping element directly against the internal spindle contour, reached its design limits, due to the cross sections and surfaces available for the force transmission. With their newly developed HSH gripper, BERG-Spanntechnik have met the requirements for clamping forces notably exceeding the values specified in DIN 69893. HSH gripper are intended for the clamping of hollow shank tooling with central cooling lubricant supply.
