PMMA polishing burn marks
Sorun Belirtisi
Burn marks and hazy spots appear on the surface during PMMA polishing
Neden Analizi
Polishing rotation speed too high or pressure too great, frictional heat softens and burns the surface; 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
Çözüm
Keep polishing rotation speed and pressure moderate; select the correct polishing compound; re-fine-polish the burned areas; after adjustment, continuously sample 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
Temel Çıkarım
Polishing thermal damage is controlled by parameters and consumables; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
