Proceso: The Step-by-Step of PAS CNC Machining
Nuestro PASA mecanizado CNC process is optimized to handle PAS’s unique properties—including its high melting point and rigidity—ensuring efficiency, calidad, and consistency at every stage.
- Diseño & Programación: Our engineers convert your 3D models into CNC code, selecting optimal técnicas de corte y selección de herramientas (p.ej., carbide tools for PAS’s abrasiveness) to minimize tool wear and maximize precision.
- Configuración de la máquina: We calibrate CNC mills, tornos, and drills to match your part’s specs—adjusting spindle speeds (1,500–10.000 rpm) y tasas de alimentación (50–500 mm/min) to avoid overheating PAS.
- Carga de materiales: Usamos alta calidad PAS resin (or reinforced grades like glass-filled PAS) cut into precise blocks to reduce waste and ensure uniform part density.
- Operaciones de mecanizado: We perform fresado CNC (para formas complejas), torneado CNC (para piezas cilíndricas), y operaciones de perforación (for holes as small as 0.5mm) with real-time torque monitoring to prevent tool breakage.
- Procesos de molienda: For parts needing ultra-smooth surfaces, we use precision grinding to achieve Ra values as low as 0.15μm—critical for medical or optical applications.
Inspección: Every part undergoes dimensional checks using digital calipers and optical comparators to verify estándares de tolerancia—we discard any parts that fall outside your required range.
Materiales: Choosing the Right PAS Grade
Not all PAS materials are identical—each grade offers unique properties to match your application’s demands. En Yigu Tecnología, we stock a full range of PAS variants to ensure optimal performance.
| PAS Grade | Propiedades clave | Aplicaciones ideales |
