GENERAL TECHNICAL INFORMATION PARTING AND GROOVING PRACTICAL TROUBLE SHOOTING 5. TO ELIMINATE CHATTER Part-off as close to chuck as possible Minimize blade overhang Improve chucking and monitor tool setup Change the RPM Increase the feed Lock the carriage on manually operated lathes 6. TO PREVENT CHIPPING OF CUTTING EDGE Use appropriate carbide grade and geometry Use insert with larger corner radii Reduce feed at end of cut Eliminate chatter Increase speed Use tougher grade Increase tool and set-up rigidity Eliminate build-up edge 7. TO PREVENT OR REDUCE BUILT-UP EDGE Use appropriate carbide grade and geometry Increase speed Reduce feed Increase coolant flow concentration. Recommended is coolant on oil base. 8. PARTING ON ECCENTRIC TUBES Inserts with 4 degree lead angle are usually recommended for tubes. However the combination of an eccentric bore and machine resiliency may increase feed snap on breakthrough and damage the cutting edge. Changing to a 8 degree lead angle insert will moderate the breakthrough. 1352
