POM machining performance
Problem Phenomenon
POM parts deform after CNC machining, and the surface melts and releases odor during high-speed machining
Cause Analysis
POM is easy to cut, but friction heat from high-speed machining softens and melts the surface; at high rotational speeds the local temperature can break through the degradation point and release formaldehyde; clamping deformation also affects accuracy
Solution
①Use sharp tools and optimize feed to reduce friction heat; ②use coolant to control temperature rise; ③configure exhaust ventilation in the machining area to prevent gas accumulation; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Heat management in POM machining is the same as in '2079851475616104452; the three-piece set of sharp tools, cooling, and exhaust prevents melting and odor; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
