  | Motor-Spindle Safety System 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 are effectively protected from the peak impact forces of the tool collision. Customer benefits: • Safely protects against spindle damage • Increases machine availability • Detects tool collisions Construction features: • Faster than purely electronic process monitoring systems • High adhesive forces and system rigidity for reliable processing • Automatic resetting of the motor spindle with high precision • Maintenance free • Adaptable to all common motor spindle geometries • Absorption of the kinetic impact energy by dampers • Integrated query of the deflection state for emergency stop • Energy self-sufficient, passive active principle • Increase in machine availability | PDF general Video clip (15.5MB) |
