Recommended Machining Parameters

【Note】

1. Please use the machine with high rigidity. It is recommended to use hydraulic，thermal expansion and strong holders with spring chucks

2. Make sure total indicated run-out(TIR) is less than 0.02mm

3. The recommended cutting condition is suitable for water-soluble cutting fluid

4. If the tool size is not listed in the table, please choose the tool size that is closest to it and adjust the cutting parameters in accordance with

the processing's actual working conditions.
