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