Note:

1. Please be sure to use water soluble coolant.

2. these milling parameters are for reference only

3. For best result, �ne parameter adjustment may be required, depending on the milling shape / application / machine used and so on.

4. Decrease both spindle speed and feed rate proportionally when the milling parameter exceed the machine’s maximum spindle speed.

5. Warning: Because of high material removal rate, you must pay attention to your chip and coolant management
