Please make adjustments according to the machining conditions. (Note 2) Vibration is liable to occur in certain cases. Please reduce the depth of cut and I or reduce cutting conditions in the following cases. When using the long shank type and extra long shank type. When using long tool overhang with the standard or arbor type. When the application has poor clamping rigidity or when using a low rigidity machine. (Note 3) In case of coarse and fine pitch cutters, the coarse pitch type is recommended to prevent vibration. (Note 4) For heavy interrupted and unstable cutting, the H breaker is first recommendation.

In this case, decrease the ramping angle or feed per tooth. 1 L (=10 / tan a). Cutters' moving distance until depth of cut reaches 10mm at a maximum ramping angle. 2 In case corner radius of 0.8mm. Other than that, find with the below formula. (cutting edge diameter DC) (comer radius) 0.2) 2 Mitsubishi Materials 1449 INDEXABLE MILLING
