Tool unsuitable

q

Only use balanced tools.

(Also see the "Tools for high speed cutting

 [

}

 32]

" section.)

q

Check whether the tool is suitable for the application.

q

Check the tool for damage.

q

Replace damaged tool.

Contamination

q

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