Recommend airblow or oil mist cutting fluids.
Remove chips to prevent heat generation and ignition.
When the parameters exceed the machine's maximum spindle speed, decrease both spindle speed and feed rate by the same proportion.
To avoid damaging the precision tip point non-contact measuring should be used.
