2. Complex geometric shapes: In particular, five-axis CNC machining produces parts with complex undercuts, deep cavity, composite curves and features on multiple planes – challenging or defeating injection molding geometry.
3. Excellent accuracy and tight tolerances: Modern CNC machines, especially 5-axis systems, can achieve microscopic tolerances (±0.005mm or more) and are essential for parts that require good fit, functional or optical clarity.
4. Upper surface surface: CNC machining can produce unusually smooth surface finishes (to RA0.4μm or higher), which is crucial for aesthetic components where low friction parts or seal integrity is required.
5. Material flexibility: CNC machining allows engineers to The best The application is engineered plastics (PEEK, PTFE, ULTEM, PSU, PVDF, nylon, polycarbonate, acetic acid) without limitations on the variability considerations of cocoa part volume. You can machine plastic injection moldings.
6. Material stability: Processing from solid stock ensures material consistency and stability throughout the section, avoiding potential problems such as warpage or internal pressure, sometimes occurring in molded parts.
