PEEK Machining Tools and Cooling
Fenómeno del problema
【Problem Phenomenon】Tools wear quickly in machining reinforced PEEK, and large-diameter parts deform during machining
Análisis de la causa
Pure PEEK can use high-speed steel tools, but fiber-reinforced grades are highly abrasive and must use carbide or coated tools; large-diameter parts accumulate cutting heat causing deformation and require reduced speed and strong cooling
Solución
Use carbide tools for reinforced grades and shorten the tool change cycle; reduce cutting speed for large-diameter parts and add forced cooling; anneal before finishing to eliminate stress and ensure dimensions; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
PEEK machining tools are selected according to filling grade; large parts use reduced speed and strong cooling to prevent deformation; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
