Clamping systems tool clamping

For HSC workpiece machining the clamping forces according 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 grippers, Berg & Co. have met the requirements for clamping forces notably exceeding the values specified in DIN 69893. HSH grippers are intended for clamping HSK tools with central cooling lubricant supply.
