Spindle clamping system
JAKOB
Tool collisions with high feed rates cause high impact force peak values on motor-spindles in metal cutting machine tools. As a result, five-figure US-$ amounts for repair and servicing of heavy collision damaged motor-spindle systems and machine tools are common.
In the case of a collision caused overload, the newly developed motor-spindle safety system from JAKOB immediately disconnects the power transmission at the interface between the machine tool headstock and the motor-spindle through 3D- displacement. Therefore the shock-sensitive components of the motor-spindle effectively get protected from the peak impact forces of the tool collision.
