Technical Information Failure and Solution Guide problem cause possible solution thread with torn finish • Use modified flank infeed. • Burs.• Torn finish.• Steps.• Improper shim.• Improper infeed.• Use full profile insert.• Increase coolant concentration.• Increases m/min.• Check machine “Z” travel axis.• Check insert form.• Check for correct shim in LT system. • Calculate flank clearance. chatter • Use modified flank infeed. • Poor rigidity. • Minimise tool overhang. • Insert movement. • Check for workpiece deflection. • Improper infeed. • Check insert and clamp. • Off centreline. • Verify that tool cutting position is at workpiece centreline. • Adjust number of passes. Fewer passes reduce chatter. built-up edge • Speed too low.• Insufficient coolant.• Chip load.• Increase m/min.• Increase coolant concentration and/or flow.• Adjust infeed angle.• Increase depth of cut per pass. deformation • Wrong grade. • Use modified flank infeed. • Speed too high. • Use a more wear-resistant grade (e.g., TN6010™). • Improper infeed angle. • Reduce m/min. • Insufficient coolant. • Increase coolant flow. chipping • Use modified flank infeed. • Increase or decrease number of passes. • Eliminate spring passes. • Improper infeed.• Chip load.• Wrong grade.• Incorrect speed.• Poor rigidity.•Use tougher grade (e.g., TN6025™).• Increase m/min if chipping on trailing edge.• Decrease m/min if chipping on leading edge.• Minimise tool overhang.• Check for insert movement/check clamp. Torque screwor clamp to correct value. • Check for possible part deflection. • Calculate flank clearance. • Ensure correct shim. broken nose • Heavy chip load. • Use modified flank infeed. • Small nose radius. • Decrease chip load. • Wrong grade. • Use large nose radius if possible. • Improper infeed. • Use tougher grade (e.g., TN6025). flank wear • Ensure correct shim. • Improper shim. • Use a more wear-resistant grade (e.g., TN6025). • Wrong grade. • Increase coolant flow. • Insufficient coolant. • Check the centreline height of the tool.
