1. Use a rigid and precise machine and holder. 2. When chattering occurs, reduce the speed and feed simultaneously. 3. Use a suitable cutting fluid with high smoke retardant.

1. The indicated speeds and feeds are for high speed light milling for use with high speed/high precision machining centers. 2. Do not use flammable fluids because tools with considerable wear can cause sparks. 3. We recommend using air blow. When using cutting fluids, use a high quality fluid with high smoke retardant.
