Materials in CNC Machining

Common Materials in CNC Machining

1. Ferrous Metals

Carbon Steel

Carbon steel is one of the most commonly used materials in CNC machining due to its strength and availability. It is classified into several categories (low, medium and high carbon) that determine its mechanical properties. This material is ideal for structures, tools and mechanical components.

Stainless Steel

Stainless steel is known for its corrosion resistance and durability. It is commonly used in applications that require hygiene, such as in the food and medical industry, as well as in aesthetic components. Machining stainless steel can be more challenging due to its hardness, so high-quality tools are required.

Cast iron

Cast iron is a heavy, dense material that is used in applications such as engine blocks and machinery parts. Its ability to be precisely machined makes it a popular choice, although its fragility can be a limitation in certain situations.

2. Non-ferrous metals

Aluminium

Aluminum is a lightweight material that is easy to machine, making it an ideal choice for applications in the automotive and aerospace industries. It offers good thermal and electrical conductivity as well as corrosion resistance. There are many aluminum alloys that can be chosen according to the specific needs of the project.

Copper

Copper is known for its high electrical and thermal conductivity. It is used in electrical applications, such as connectors and cables, as well as in refrigeration systems. Although it is a soft material, its machining can be tricky due to its tendency to stick to cutting tools.

Titanium

Titanium is an extremely strong and corrosion-resistant material, used in aerospace and medical applications. However, it is more difficult to machine due to its hardness and elasticity. Specialized tools and proper machining techniques are required to ensure effective production.

3. Plastics

Polycarbonate

Polycarbonate is a thermoplastic plastic known for its impact resistance and optical clarity. It is used in the manufacture of housings and components where a light and strong material is required. It is easy to machine, although it poses risks of cracking if it gets too hot.

Acrylic

Acrylic is another popular thermoplastic that is used for decorative and functional applications. It is easily machined and can be molded and cut into various shapes. Its transparency and finishing capabilities allow you to create high-quality, aesthetic products.

Nylon

Nylon is a plastic that offers good abrasion resistance and favorable mechanical properties. It is used in machinery parts, gears, and components that require durability. Its ability to be machined makes it a popular material in the manufacturing industry.

4. Composites

Carbon Composites

Carbon composites are used in applications where high strength and low weight are required, such as in aerospace and automotive. Although its machining can be more delicate, modern techniques have allowed it to be properly manipulated to create precise components.

Fiberglass

Fiberglass is a composite material that combines glass and resins. It is used in the construction industry and in consumer products. Although it is less common than metals, it can be machined with specific techniques and is valued for its lightness and strength.
