POM Machined Parts
ظاهرة المشكلة
POM machined parts delaminate and crack during drilling
تحليل الأسباب
Residual stress or voids inside the rod stock release during drilling and cause cracking; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
الحل
Select dense, void-free rod stock; perform aging treatment before drilling; use sharp drill bits with low-speed feed; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
الخلاصة الأساسية
Machined parts require dense rod stock plus aging; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
