What Is Acrylic CNC Machining?
Mecanizado CNC de acrílico is a computer-controlled manufacturing process that shapes Acrílico (scientifically called Metacrilato de polimetilo (PMMA))—un versátil Engineering Plastic y Transparent Plastic—into custom, piezas precisas. Unlike manual cutting, it uses automated tools to follow digital blueprints, ensuring consistency in Propiedades de los materiales como alta claridad and impact resistance.
Este Proceso de mecanizado is ideal for PMMA because it avoids common issues like cracking or clouding that can ruin the material’s transparency. By leveraging tools like CNC mills and lathes, it transforms raw acrylic stock (hojas, varillas, o bloques) into parts ranging from tiny electronic components to large display cases—all while preserving the material’s unique advantages, such as light transmission (arriba a 92%, nearly matching glass).

The Acrylic CNC Machining Process
Nuestro Mecanizado CNC de acrílico El proceso es estructurado., quality-focused workflow designed to protect acrylic’s transparency while ensuring precision. Each step is optimized to minimize waste and deliver reliable results:
- Diseño & File Preparation: We convert customer CAD files (PASO, IGES) into machine-readable G-code, accounting for acrylic’s brittleness to avoid cracking during cutting.
- Configuración de la máquina: Technicians select Selección de herramientas (high-speed steel or carbide endmills) and secure acrylic stock with non-marring clamps to prevent surface scratches.
- CNC Milling/Turning: Fresado CNC shapes flat or 3D parts (p.ej., display case frames), mientras Torneado CNC creates cylindrical components (p.ej., difusores de iluminación).
- Operaciones de perforación: Operaciones de perforación create precise holes (as small as 0.3mm) with slow feed rates to prevent chipping at hole edges.
- Técnicas de corte: We use low-speed, high-feed cutting for thick acrylic and high-speed cutting for thin sheets—both with compressed air cooling to avoid melting (which clouds transparency).
- Procesos de molienda: Optional Procesos de molienda smooth rough edges, preparing parts for surface treatment.
- Tratamiento superficial: Final steps like flame polishing or sandblasting refine the finish (ver sección 5).
- Inspección: Cada parte sufre Técnicas de medición (optical scanners for transparency checks, CMM for dimensions) para garantizar el cumplimiento.
Below is a table of key process parameters for different acrylic types:

Surface Treatment for Acrylic CNC Parts
Tratamiento superficial enhances acrylic parts’ appearance, durabilidad, and functionality—critical for maintaining transparency or adding texture. Our key offerings include:
- Pulido: Crea un acabado tipo espejo. (Ra 0.01–0.05μm) to maximize light transmission; ideal for optical components or display cases.
- Flame Polishing: Uses controlled heat to melt and smooth acrylic edges, eliminating scratches without reducing clarity—perfect for signage or lighting fixtures.
- Revestimiento: Aplica capas protectoras (p.ej., antiarañazos, anti-glare, or anti-fingerprint coatings) to extend part life; common in touchscreen panels.
- Cuadro: Uses acrylic-specific paints for colored accents (p.ej., branded logos on display cases); ensures paint adheres without peeling.
- Arenado: Crea un mate, frosted surface (Ra 1.0–3.0μm) for privacy (p.ej., medical device windows) or decorative effects.
- Tratamiento térmico: Reduces internal stress in thick acrylic parts to prevent warping over time—critical for large display cases.
Acabado de superficies: Final steps like deburring (removing small plastic burrs) ensure parts are ready for immediate use or assembly.
Tolerancias: Ensuring Precision in Acrylic Parts
En Mecanizado CNC de acrílico, Tolerancias are critical—even small dimensional variations can ruin a part’s fit (p.ej., an electronic enclosure window) or transparency (p.ej., a medical lens). We adhere to strict standards and use advanced Métodos de inspección to guarantee accuracy:
Key Tolerance Metrics for Acrylic Parts
| Tipo de tolerancia | Rango típico | Herramienta de medición | Ejemplo de requisitos de la industria |
