Nel mondo della produzione, CNC (Controllo numerico computerizzato) le macchine utensili sono diventate indispensabili, soprattutto grazie alla loro capacità di lavorare con una vasta gamma di materiali. Che tu stia realizzando parti aerospaziali, dispositivi medici, o prodotti di uso quotidiano, knowing what materials CNC machine tools can machine helps you choose the right option for your project. Sotto, we’ll break down the most common materials, i loro tratti chiave, usi nel mondo reale, and data to guide your decisions.
1. Materiali metallici: The Backbone of Industrial CNC Machining
Metals are the most widely used materials in CNC machining, valued for their strength, durabilità, e versatilità. Macchine utensili CNC excel at cutting, modellare, 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 |
| Lega di alluminio | Leggero, resistente alla corrosione, facile da tagliare | Parti aerospaziali, componenti automobilistici | Fast machining speed (30% faster than steel) |
| Acciaio inossidabile | Resistente alla corrosione, alta resistenza | Dispositivi medici, attrezzature per la lavorazione degli alimenti | Consistent precision (Tolleranza di ±0,005 mm) |
| Acciaio legato | Difficile, resistente all'usura | Knives, stampi, mechanical structures | Handles high-hardness materials (fino a 60 HRC) |
| Leghe di rame | Excellent electrical/thermal conductivity | Connettori elettronici, dissipatori di calore | Smooth surface finish (Ra 0,8μm) |
| Leghe di titanio | Elevato rapporto resistenza/peso, resistente al calore | Parti aerospaziali, attrezzature sportive | Minimizes material waste (soltanto 5% scrap) |
Real-World Case
Era necessario un produttore leader nel settore aerospaziale 100 aluminum alloy brackets for a new aircraft. Utilizzando Macchine utensili 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. Materie plastiche: Conveniente & Versatile for CNC Projects
Plastics are ideal for projects needing lightweight, basso costo, or corrosion-resistant parts. Macchine utensili CNC handle plastics easily, producing precise components for consumer goods, elettronica, e altro ancora.
Top CNC-Machined Plastics (with Examples)
- PVC (Cloruro di polivinile): 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 (Acrilonitrile-Butadiene-Stirene): Tough and impact-resistant, perfect for toys (per esempio., Lego bricks) and automotive interiors. A toy manufacturer used CNC to make ABS prototypes, reducing design iteration time from 4 settimane a 1 settimana.
- Polipropilene (PP): Chemically resistant, used for food containers and industrial parts. A beverage company used CNC-machined PP caps to test 5 designs, risparmio $3,000 nei costi degli utensili.
- Policarbonato (computer): 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. Legna & Wood-Based Materials: For Furniture & Decor
Wood is a classic material for CNC machining, especially for custom furniture, decor, and crafts. Macchine utensili 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 unità.
- 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. Materiali compositi: High-Performance Options for Specialized Needs
Compositi (materials made of two or more components) offer unique properties like high strength or light weight. Macchine utensili 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% pur mantenendo la forza.
- Plastica rinforzata con fibra di vetro (GFRP): Resistente alla corrosione, 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: Ceramica & Metalli teneri
Macchine utensili CNC also handle less common but critical materials, expanding their use in medical and luxury industries.
- Ceramica: 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.
- Metalli teneri (Oro, Argento, Platino): Used for jewelry and decorations. A luxury jewelry brand used CNC to create intricate gold prototypes—cutting production time from 5 giorni a 1 day and reducing waste from 20% A 3%.

Domande frequenti
- Q: Can CNC machine tools handle both hard and soft materials in the same project?
UN: SÌ! CNC machines can switch tools and adjust cutting speeds to machine mixed materials (per esempio., 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?
UN: Polipropilene (PP) and aluminum alloy are among the cheapest—they’re easy to cut (reducing machining time) and have low material costs. Per esempio, 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?
UN: NO. Modern CNC tools use optimized cutting paths that minimize waste—even for hard materials. Titanium typically has only 5-8% scrap with CNC, rispetto a 15-20% with manual machining.
