1. Please work with good rigidity / high precision facilities and collet chuck. 2. Please choose proper cutting fluid.
3. The cutting data is reference value only. Please adjust it according to your real working conditions. 4. If RPM is lower the reference value, the Feed rate (fz) and RPM should be reduced by the same proportion. 5. If vibration occurs during cutting, please reduce cutting parameter.
