 [

}

 28]

" section.)

q

Check whether the tool is suitable for the application.

q

Check the tool for damage.

q

Replace damaged tool.

Contamination

q

Frequency converter
incorrectly set

q

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

Machining too heavy

q

Reduce the machining load intensity.

Mounting screws are
loose

q

Tighten the screws securely.
