ABSTRACT:
A process and the device necessary for the measurement of the draw-in force of a tool into the spindle of a machine too. The measuring device has a bolt on which a draw-in nipple is attached at the front. A ring-shaped pressure measuring cell and a centering casing are placed onto the bolt. An axial adjustable stop nut is screwed onto the end of the bolt opposed to the draw-in nipple. For the correct adjustment of the measuring device, so that its draw-in nipple projects into the spindle boring precisely as far as the nipple of the tool holder did previously, a gauge is used which has an adjusting ring and a distance measuring rod and nose piece.
