Cutting Parameters

★ Please pay special attention:
1：The following table contains standard values for side milling. When cutting grooves with a tool, the rotational speed should be 50%-70% of the values in the table, and the feed rate should be 40%-60% of the standard value.
2：Please use high-precision machine tools and tool holders.
3：Please use air cooling or cutting fluids that do not easily produce smoke.
4：Conventional milling is recommended for side milling.
5：When the rigidity of the machine tool and workpiece installation is poor, vibration and abnormal sounds may occur. In this case, the rotational speed and feed rate in the table should be proportionally reduced.
6：Under conditions that do not interfere, make the tool overhang as short as possible.
