1. Use a rigid and precise machine and holder. 2. We suggest using air blow or MQL (mist).
3. When using low speed machines, use the maximum speed and adjust feed rate. 4. During heavy load operations such as corner processing, reduce the speed and feed. 5. The run out of the end mill should be within 10 microns (.0004’’) after chucking.
