Nature Of Material:

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Considerations when selecting materials for CNC machining

When selecting CNC machining materials, the following key factors need to be considered comprehensively to ensure machining results and productivity:

Material selection:

Selection of suitable materials is based on mechanical properties, wear resistance, corrosion resistance, heat resistance, vibration resistance and cost.

Stress loads:

Evaluate the stress loads to which the part will be subjected to ensure that the selected material will be able to withstand the high stresses without deformation or rupture.

Dimensional tolerances: 

Accurate dimensional tolerances are critical, not only for part fit, but also for cutting methods and equipment selection. Adjust to the tolerance requirements of the part to ensure optimum performance.

Operating Temperature:

Select materials whose heat resistance meets process requirements to ensure material stability and durability at extreme temperatures.

Application scenarios:

Select the right material for the specific application and consider how the material will perform in the given environment.

Material compatibility:

Ensure that the selected material is compatible with the machining equipment and tools to improve productivity and machining quality.
