matters needing attention
1. Please use high-precision machine tools and tool handles.
2. Please use air cooling or cutting fluid that is not easy to produce smoke.
3. When the machine tool and workpiece are installed with poor rigidity, vibration and abnormal sound will occur. At this time, the speed and feed speed in the above table should be reduced year-on-year.
4. Make the tool overhang as short as possible without interference.
