What Materials Are Used for CNC Turning?

1. Metals
Metals rank among the most widely used materials for CNC turning. Manufacturers frequently choose several types of metals, including:
Aluminum: This lightweight and corrosion-resistant metal is easy to machine.
Steel: Known for its strength and durability, steel comes in different grades, such as stainless and carbon steel.
Brass: This metal boasts excellent machinability.

2. Plastics
Plastics also gain popularity in CNC turning.
Acrylic: This transparent plastic works well for optical applications.
Polycarbonate: Known for its impact resistance, polycarbonate suits safety equipment and electronic housings.
Nylon: This strong plastic exhibits excellent wear resistance.

3. Composites
Composite materials combine two or more different substances, offering enhanced properties.
Carbon Fiber: This lightweight material provides incredible strength.
Glass Fiber Reinforced Plastics (GFRP): GFRP combines glass fibers with resin, resulting in a lightweight and strong material.

4. Hard Materials
CNC turning also accommodates hard materials, which require special tooling and techniques. Examples include:
Titanium: This metal is renowned for its strength-to-weight ratio.
Hardened Steel: This type of steel undergoes heat treatment, making it tough and durable.

5. Specialty Alloys
Specialty alloys are engineered to provide specific properties, making them suitable for demanding environments. For example:
Inconel: This nickel-chromium alloy resists heat and corrosion effectively.
Monel: This copper-nickel alloy offers excellent resistance to seawater and acids.

6. Wood
Although less common, wood can also undergo CNC turning. Both softwoods and hardwoods suit the creation of decorative and functional items. CNC technology enables intricate designs in furniture and crafts.

In summary, a wide range of materials serves well in CNC turning.
