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.

The spindle is the most essential part of a machine tool. Maintaining the accuracy of the spindle is almost equal to extending the life of the machine tool itself.
Even periodical inspection of the runout accuracy makes a large difference.
