Technical section TROUBLESHOOTING Application problems with new thread milling cutters Problem Possible causes Solution 1. Thread produced is too large or too small 2. Thread not cylindrical 3. Thread surface not according to requirements, chatter marks 4. Tool breakage 5. Tool life insufficient Incorrect radius in CNC program and Correct milling radius until thread is therefore milling of incorrect circle dimensionally correct Feed rate too high Synchronous milling path with long threads Cutting speed too high Insufficient tool or workpiece clamping CNC program error Cutting rates too high Cutting rates too high Tool applied uncoated Insufficient lubrication and chip evacuation 6. Tool breakage with drill/milling cutter Chip problems when drilling Reduce feed rate Modify milling direction to opposite direction Adjust cutting speed Check tool and workpiece clamping Check CNC program Adjust cutting rates Adjust cutting rates Apply coated tool Improve lubrication, coolant delivery via the spindle Apply tool with IC Feed rates too high when drilling Incorporate pecking cycles 818 GUHRING
