Troubleshooting

Tool unsuitable

Only use balanced tools.

(Also see the "Tools for high speed cutting

Check whether the tool is suitable for the application.

Check the tool for damage.

Replace damaged tool.

Contamination

Remove all contamination between the tool taper and shaft
of the HF spindle.

(Observe all points in the “Tool change

” sections.)

Frequency converter
incorrectly set

Compare the values for the HF spindle with the set values on
the frequency converter.

Machining too heavy

Reduce the machining load intensity.

Mounting screws are
loose

Tighten the screws securely.
