• Before using the tool，please measure the accuracy tolerance of the tool，if the tool accuracy exceeds 0.01mm，please correct it before cutting.

• The shorter the tool protrudes from the collect,the better.If the tool protrudes longer,it is necessary to reduce the speed,feed rate or cutting volume。

• If producing abnormal vibration or sound during cutting,reducing the speed and cutting amount until the situation improves.

• The best way to the steel cooling is spray jet and air jet,which can improve the use of milling cutters.
