GROOVING / CUTTING OFF GROOVING / CUTTING OFF MACHINING RECOMMENDATIONS Notes on multi-functional machining (BM breaker) Roughing L J HJse plunging and cross-feed machining. When machining the corner, vibration is likely to occur. To avoid this, reduce the feed by 50%. Finishing n p) \ APMX 2 Carry out finishing in one process. For the depth of cut (APMX 2) when back turning, refer to the table on the right.

Revolution Spindle speed> DCx0.5 When using constant cutting speed during a cutting off cycle, it is recommended to limit the spindle speed to 80% of maximum to ensure stability. To prevent the workpiece from being expelled, lower the spindle speed before finishing the grooving operation. Insert Neutral insert Handed insert Neutral insert Handed insert When there is a centre stub on solid bar work or burrs are formed on pipe material, it is possible to decrease them by using a handed insert. With a handed insert, machining tends to be less stable when compared to using a neutral insert. Pay special attention to avoid fracturing of the cutting edge and decrease the feed when necessary.
