Proceso: How PMMA CNC Machining Works
El PMMA CNC Machining process flow is a structured sequence of steps, each optimized to address PMMA’s unique characteristics (p.ej., sensitivity to heat, tendency to chip). Below is a step-by-step explanation of our production process:
- Diseño & Programación: Our engineers review your 3D CAD files to create a detailed Proceso de mecanizado CNC program. We select the right tools and procedures (p.ej., low-speed cutting to avoid overheating) to prevent PMMA damage.
- Preparación de materiales: Obtenemos alta calidad PMMA materials (matched to your project’s needs, p.ej., clear PMMA for optics) and cut them into blanks that fit our CNC machines. Each blank is inspected for defects (p.ej., rayones, burbujas) before machining.
- Configuración de la máquina: Técnicos calibran máquinas CNC, instalar herramientas especializadas (p.ej., high-speed steel cutters for clean PMMA edges), and secure the blank with non-marring fixtures to avoid surface damage.
- Rough Machining: We remove excess material using high-speed milling or turning. Coolants are used to reduce heat buildup—critical for preventing PMMA warping or melting.
- Finishing Operations: The part undergoes precision trimming, engraving (si es necesario), y tratamiento superficial (p.ej., pulido) to achieve the desired calidad de la superficie and tolerances. For parts needing extra protection, aplicamos coatings (p.ej., anti-scratch layers).
Inspección & Control de calidad: Every PMMA part is tested using tools like CMM (Máquina de medición de coordenadas) and optical comparators to verify precisión dimensional y niveles de tolerancia. Only parts that meet our strict standards (ISO 9001 certificado) are shipped.
