CNC (Computer Numerical Control) machining is a versatile manufacturing method that can work with a broad range of materials, depending on the specific CNC machine and the cutting tools equipped. Here's a rundown of materials commonly processed using CNC machining:


  1. Aluminum: Widely used due to its lightweight, good strength-to-weight ratio, and ease of machining.
  2. Stainless Steel: Known for its corrosion resistance and strength.
  3. Brass: Easy to machine and offers excellent electrical properties.
  4. Copper: Preferred for electrical components due to its conductivity.
  5. Titanium: Strong and lightweight but can be challenging to machine. Often used in aerospace applications.
  6. Bronze: Offers good corrosion resistance and is commonly used for bearings, bushings, and statues.
  7. Magnesium: Lightweight and often used in aerospace and automotive sectors.
  8. Tungsten: Extremely hard and dense, used in specialized applications like darts, weights, and radiation shielding.
  9. Zinc: Often machined for components in the electronics and automotive industries.


  1. ABS (Acrylonitrile Butadiene Styrene): Common and versatile plastic.
  2. Polycarbonate (PC): Known for its transparency and impact resistance.
  3. Polyethylene (PE): Common in consumer goods due to its flexibility.
  4. Polypropylene (PP): Resistant to chemicals and commonly used for containers.
  5. PTFE (Polytetrafluoroethylene): Also known as Teflon, this material offers high temperature resistance and a low coefficient of friction.
  6. Nylon (Polyamide): Durable and wear-resistant.
  7. POM (Polyoxymethylene): Also known as Acetal or Delrin, it's known for its rigidity and resistance to wear.
  8. PMMA (Polymethyl Methacrylate): Often called acrylic or Plexiglass, it's a transparent and shatter-resistant alternative to glass.
  9. PEEK (Polyether Ether Ketone): A high-performance plastic known for its mechanical and chemical resistance.


  1. Wood & Wood Composites: Various species from softwoods like pine to hardwoods like oak can be CNC machined. Additionally, MDF (Medium Density Fiberboard) and plywood are common wood composites that can be machined.
  2. Foam: Used for prototypes, packaging, and molds. Examples include polyurethane and expanded polystyrene.
  3. Ceramics: Some ceramics, especially those used in electronics, can be CNC machined.
  4. Composites: Materials like carbon fiber and fiberglass can be machined, though special tooling might be required due to their abrasive nature.

In choosing a material for CNC machining, it's essential to consider the desired properties of the final product, machining costs, and any post-processing requirements.
