En el mundo de la fabricación., CNC (Control numérico por computadora) Las máquinas herramienta se han vuelto indispensables, en gran parte gracias a su capacidad para trabajar con una amplia gama de materiales.. Ya sea que esté fabricando piezas aeroespaciales, dispositivos médicos, o productos cotidianos, knowing what materials CNC machine tools can machine helps you choose the right option for your project. Abajo, we’ll break down the most common materials, sus rasgos clave, usos del mundo real, and data to guide your decisions.
1. Materiales metálicos: The Backbone of Industrial CNC Machining
Metals are the most widely used materials in CNC machining, valued for their strength, durabilidad, y versatilidad. máquinas herramienta cnc excel at cutting, organización, and finishing various metals, from lightweight alloys to high-strength steels.
Common CNC-Machined Metals & Their Applications
| Metal Type | Key Traits | Typical Uses | CNC Machining Advantage |
| Aleación de aluminio | Ligero, resistente a la corrosión, fácil de cortar | Piezas aeroespaciales, componentes automotrices | Fast machining speed (30% faster than steel) |
| Acero inoxidable | Resistente a la corrosión, alta resistencia | Dispositivos médicos, equipo de procesamiento de alimentos | Consistent precision (Tolerancia de ±0,005 mm) |
| Acero aleado | Duro, resistente al desgaste | cuchillos, moldes, mechanical structures | Handles high-hardness materials (arriba a 60 CDH) |
| Aleaciones de cobre | Excellent electrical/thermal conductivity | Conectores electrónicos, disipadores de calor | Smooth surface finish (Ra 0,8μm) |
| Aleaciones de titanio | Alta relación resistencia-peso, a prueba de calor | Piezas aeroespaciales, equipo deportivo | Minimizes material waste (solo 5% chatarra) |
Caso del mundo real
Se necesita un fabricante aeroespacial líder 100 aluminum alloy brackets for a new aircraft. Usando máquinas herramienta cnc, they completed the order in 3 days—with zero defects. Manual machining would have taken 10 days and resulted in 8-10% defective parts due to aluminum’s softness.
2. Materiales plasticos: Rentable & Versatile for CNC Projects
Plastics are ideal for projects needing lightweight, bajo costo, or corrosion-resistant parts. máquinas herramienta cnc handle plastics easily, producing precise components for consumer goods, electrónica, y más.
Top CNC-Machined Plastics (with Examples)
- CLORURO DE POLIVINILO (Cloruro de polivinilo): Rigid yet flexible, used for pipes and cable insulation. A construction company used CNC-machined PVC parts to build custom pipe fittings—cutting installation time by 25%.
- ABS (Acrilonitrilo-butadieno-estireno): Tough and impact-resistant, perfect for toys (p.ej., Lego bricks) and automotive interiors. A toy manufacturer used CNC to make ABS prototypes, reducing design iteration time from 4 semanas para 1 semana.
- polipropileno (PÁGINAS): Chemically resistant, used for food containers and industrial parts. A beverage company used CNC-machined PP caps to test 5 designs, ahorro $3,000 en costos de herramientas.
- policarbonato (ordenador personal): Transparent and shatterproof, used for bulletproof glass and spectacle lenses. An optics firm used CNC to machine PC lenses with 99.9% clarity—something manual cutting couldn’t achieve.
3. Madera & Wood-Based Materials: For Furniture & Decor
Wood is a classic material for CNC machining, especially for custom furniture, decor, and crafts. máquinas herramienta cnc create intricate designs (like engravings or 3D carvings) that are hard to replicate by hand.
CNC-Machined Wood Types
- Solid Wood: Used for high-end furniture and crafts. A furniture maker used CNC to carve a 3D floral pattern on oak tables—producing 20 tables in 1 week vs. 2 tables with manual carving.
- Plywood: Layered for strength, ideal for cabinetry. A kitchen brand used CNC-machined plywood cabinets to ensure uniform dimensions across 500 unidades.
- MDF (Medium-Density Fiberboard): Smooth surface for painting, used in interior decor. A hotel chain used CNC-cut MDF wall panels to create a custom geometric design—saving 40% on labor costs.
4. Materiales compuestos: High-Performance Options for Specialized Needs
compuestos (materials made of two or more components) offer unique properties like high strength or light weight. máquinas herramienta cnc are essential for machining these materials, as they require precise cutting to avoid delamination.
Key CNC-Machined Composites
- Carbon Fiber Reinforced Plastic (CFRP): Lightweight and strong, used in aerospace and sports equipment. A bicycle manufacturer used CNC to machine CFRP frames—reducing frame weight by 30% manteniendo la fuerza.
- Plástico reforzado con fibra de vidrio (PRFV): Resistente a la corrosión, used in automotive and marine parts. A boat builder used CNC-machined GFRP hull components to improve fuel efficiency by 15%.
5. Other Specialized Materials: Cerámica & Metales blandos
máquinas herramienta cnc also handle less common but critical materials, expanding their use in medical and luxury industries.
- Cerámica: Hard and heat-resistant, used for medical implants and precision components. A medical device company used CNC to machine ceramic hip implants—achieving a tolerance of ±0.002mm, essential for patient safety.
- Metales blandos (Oro, Plata, Platinum): Used for jewelry and decorations. A luxury jewelry brand used CNC to create intricate gold prototypes—cutting production time from 5 días para 1 day and reducing waste from 20% a 3%.

Preguntas frecuentes
- q: Can CNC machine tools handle both hard and soft materials in the same project?
A: Sí! CNC machines can switch tools and adjust cutting speeds to machine mixed materials (p.ej., a metal bracket with a plastic insert). Just ensure the machine is calibrated for each material’s traits.
- q: Which material is the cheapest to machine with CNC tools?
A: polipropileno (PÁGINAS) and aluminum alloy are among the cheapest—they’re easy to cut (reducing machining time) and have low material costs. Por ejemplo, machining a PP part costs 50% less than a titanium part of the same size.
- q: Do CNC machine tools produce more waste with hard materials like titanium?
A: No. Modern CNC tools use optimized cutting paths that minimize waste—even for hard materials. Titanium typically has only 5-8% scrap with CNC, en comparación con 15-20% with manual machining.
