Danger of collision!

The rotation of the workpiece creates centrifugal forces that

lead to vibration (resonance), depending on the unbalance. This

vibration has a negative effect on the machining process and

reduces the tool life.

Select the technological data to avoid vibration (resonance)

Turn a test cut before the actual machining operation to

ensure that the required speeds can be attained.

The linear axis positions resulting from the
