PTFE Machining Chipping
Problembeschreibung
Edge chipping, cracks, and dimension out-of-tolerance during PTFE machining, short tool life, unstable machining quality.
Ursachenanalyse
PTFE semi-crystalline structure brittleness; dull tools with large cutting force; internal stress in material released during machining causing deformation; improper cutting parameters.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Lösung
①Sharp tools with low cutting force; ②Select low-stress materials; ③Optimize cutting parameters; ④Dimensional aging verification after machining.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Wichtigste Erkenntnis
PTFE machining must control cutting force and stress; tool sharpness is the foundation; aging verification ensures precision.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
