The Most common 11 Materials We Use For Precision CNC Machining
With the passage of time, more and more CNC machining has appeared around us. As we known,One of the great advantages to using CNC machining is its versatility. That’s because precision CNC milling and turning works successfully with a very wide variety of raw materials to produce finished parts. This gives design engineers many options when it comes to creating prototypes and commercial products.
In this section, we will learn the various common materials that are valuable for CNC machining. We’ve listed these materials below.
1.ABS (Acrylonitrile Butadiene Styrene):
ABS is a thermoplastic polymer known for its toughness and impact resistance. It is commonly used in applications such as prototyping, automotive parts, enclosures, and consumer goods. ABS offers good strength and durability, is easy to machine, is available in various colors, and is cost-effective.
2.ACM Panel (Aluminum Composite Material):
ACM panel is a lightweight composite material consisting of a thin aluminum sheet bonded to a polyethylene or fire-retardant core. It finds applications in signage, architectural cladding, exhibition displays, and interior design. ACM Panel provides excellent flatness, a high strength-to-weight ratio, weather resistance, and ease of shaping and cutting, making it suitable for outdoor use.
3.Aluminum:
Aluminum is a lightweight metal known for its strength, corrosion resistance, and conductivity. It is commonly used in machine parts, common household hardware, automotive components, and enclosures. Aluminum provides a high strength-to-weight ratio, good thermal and electrical conductivity, and corrosion resistance.
4.Brass:
Brass is an alloy composed of copper and zinc, known for its attractive appearance and easy machinability. It is used in applications such as decorative items, jewelry, hardware, and musical instruments. Brass also offers good corrosion resistance and antimicrobial properties.
5.Composites:
CNC routing is used to process composite materials, including fiberglass-reinforced plastic (FRP), carbon-fiber-reinforced plastic (CFRP), and other composite laminates. CFRP exhibits high strength and stiffness, is light for its strength, has excellent fatigue resistance, and low thermal expansion. This material is widely used in the aerospace, automotive, marine, and sports industrie
6.Baltic Birch Plywood:
Baltic birch plywood is a type of plywood made from multiple layers of birch veneer. It is known for its strength and durability. It is commonly used in furniture, cabinetry, jigs, and decorative items. Baltic birch plywood offers stability, void-free construction, high strength, good screw-holding ability, and suitability for intricate cuts and engraving.
7.HDPE (High-Density Polyethylene):
HDPE is a versatile thermoplastic known for its high strength-to-weight ratio and resistance to chemicals. It finds applications in kitchen cutting boards, marine applications, wear strips, and storage containers. HDPE is lightweight, exhibits excellent chemical resistance, has low moisture absorption, is easy to machine, and is cost-effective.
8.MDF (Medium-Density Fiberboard):
MDF is a type of engineered wood product that is manufactured by breaking down residuals of hardwood or softwood into wood fibers. These fibers are then combined with resin and compressed to form a dense and uniform board. MDF finds widespread use in applications such as cabinetry, furniture, signage, and decorative panels. One of its key advantages is the smooth and consistent surface it offers. MDF is also highly machinable, making it easy to shape and carve. Additionally, it is known for its affordability, stability, and suitability for painting and veneering processes.
9.Polycarbonate:
Polycarbonate is a transparent thermoplastic known for its high impact resistance and clarity. It is used in applications such as protective screens, machine guards, lenses, and electronic components. Polycarbonate exhibits excellent impact resistance, high optical clarity, ease of shaping and forming, and good electrical insulation properties.
10.UHMW (Ultra-High Molecular Weight Polyethylene):
UHMW is a tough and abrasion-resistant thermoplastic with a high molecular weight. It finds applications in bearings, wear strips, conveyor components, and chute liners. UHMW offers excellent abrasion resistance, self-lubrication, low friction, and high impact strength.
11.Foam:
CNC routing is commonly employed in cutting and shaping foam materials such as expanded polystyrene (EPS) and polyurethane foam. Foam is frequently used in packaging, insulation, theatrical props, and architectural modeling.
Although these are the most common Materials we use for most CNC milling and turning jobs, there are many more available to suit almost any application.
