CNC machining is a manufacturing process in which computer numerical control (CNC) machines are used to cut and shape materials into a specific design or shape. CNC machining can be used to produce parts and components from a wide range of materials, including plastics.

There are many different types of plastics that can be used in CNC machining, each with its own unique properties and characteristics. Some common plastics used in CNC machining include:

Acetal (POM): Acetal is a strong and rigid plastic that is resistant to wear and has good fatigue resistance. It is often used in the production of gears, bearings, and other mechanical parts.
Acrylonitrile-butadiene-styrene (ABS): ABS is a strong and durable plastic that is resistant to impact and has good dimensional stability. It is often used in the production of automotive parts, toys, and other products.
Polycarbonate (PC): Polycarbonate is a strong and transparent plastic that is resistant to impact and has good electrical insulation properties. It is often used in the production of electronic components, such as circuit boards, and in the construction of greenhouse covers.
Polyethylene (PE): Polyethylene is a soft and flexible plastic that is resistant to impact and has good chemical resistance. It is often used in the production of packaging materials and in the construction of inflatable products.
Polypropylene (PP): Polypropylene is a strong and lightweight plastic that is resistant to impact and has good chemical resistance. It is often used in the production of food packaging materials and in the construction of automotive parts.

When selecting a plastic for CNC machining, it is important to consider the specific properties and characteristics of the plastic, as well as the requirements of the application. This will help ensure that the right material is used to produce parts and components that meet the desired performance and functionality requirements.
