What are some common materials that can be effectively milled using CNC machines?

CNC milling machines are used in various applications; metal, plastic, or wood can be milled efficiently and accurately. Here are some common materials that can be effectively milled using CNC machines:

CNC milling


CNC milling is widely used in metalworking industries due to its ability to handle various metals. Some commonly milled metals include:


Aluminum is a lightweight material with excellent machinability. It is commonly used in aerospace, automotive, and electronic industries. CNC milling can achieve precise cuts and intricate designs on aluminium parts.


Steel is widely used in manufacturing, construction, and engineering applications. CNC milling machines can effectively mill different types of steel, including carbon steel, stainless steel, and tool steel.

Brass and Copper

Brass and copper are malleable materials commonly used in electrical components, plumbing fittings, and decorative applications. CNC milling can accurately shape and carve intricate patterns on brass and copper parts.


CNC milling is well-suited for machining various types of plastics. Some examples include:


Acrylic, or PMMA (polymethyl methacrylate), is a transparent plastic widely used in signage, displays, and lighting fixtures. CNC milling can achieve smooth finishes and precise cuts on acrylic sheets.

ABS (Acrylonitrile Butadiene Styrene)

ABS is a popular thermoplastic known for its durability and impact resistance. It is commonly used in automotive parts, consumer electronics, and household products. CNC milling can accurately shape and machine ABS components.

Polyethene (PE) and Polypropylene (PP)

PE and PP are widely used thermoplastics with excellent chemical resistance and low friction properties. They are commonly used in packaging, medical devices, and automotive components. CNC milling can efficiently create intricate features on PE and PP parts.

Wood and Composites

CNC milling is extensively used in woodworking and composite material industries. Some examples include:


CNC milling can effectively shape and carve hardwoods such as oak, maple, and walnut. It is commonly used in furniture manufacturing, cabinetry, and artistic woodworking.

Medium-Density Fiberboard (MDF) and Particle Board

MDF and particle board are engineered wood products commonly used in furniture, shelving, and interior applications. CNC milling machines can precisely cut and shape these materials, allowing for intricate designs and patterns.

Fibreglass and Carbon Fiber Composites

CNC milling machines composite materials like fibreglass and carbon fibre. These materials are widely used in aerospace, automotive, and sporting goods industries. CNC milling enables precise shaping and drilling of composite parts.


CNC milling machines offer exceptional versatility in material machining, enabling precise and efficient milling operations.

This article explores some of the most common materials that can be effectively milled using CNC machines.

Metals such as aluminum, steel, brass, and copper are frequently milled due to their widespread use in industries like aerospace, automotive, and electronics.

Plastics like acrylic, ABS, and polyethylene are also well-suited for CNC milling, with applications ranging from signage to automotive components. Wood and composite materials, including hardwoods, MDF, particle board, and fiberglass composites, find excellent use in furniture, cabinetry, and aerospace industries.

By utilizing CNC milling techniques, manufacturers can achieve intricate designs, precise cuts, and exceptional finishes across a broad range of materials, unlocking new possibilities in precision machining.
