DYNAMIC

Measures dynamic runout of machine spindle during rotation. Knowing the dynamic accuracy of the machine tool spindle affected by centrifugal forces, vibrations and heat will aid in finding the appropriate cutting parameters for actual machining.

DYNA FORCE Tool clamp measuring device for measuring pulling force of machine tool spindle, a vital factor of machine tool performance. The pulling force produced by the clamping device of machine tools could deteriorate due to degradation of disc springs or wear of the components of the amplifier. Pulling force is especially vital when it comes to dual face contact spindle interface, thus regular inspection is recommended.
