Common Materials for CNC Machining

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.

Factory Environment

What is CNC Machining?

CNC machining is a widely used manufacturing process that uses high-speed cutting tools to automatically create designs from metal or plastic stock. Standard CNC machines include 3-, 4- and 5-axis mills, lathes and routers, and parts are cut in different ways. The workpiece can stand still while the tool moves, the tool can stand still while the workpiece rotates and moves, or the tool and workpiece can move in tandem.

Skilled machinists program CNC machines from CAD models to cut precise and repeatable toolpaths for custom parts.CNC machining is available for virtually any metal or rigid plastic, so it can serve a wide range of industries, from aerospace and automotive automation to electro-mechanical devices and more.

Allied’s CNC machining offers custom CNC services for more than 50 materials, from plain aluminum to high-grade titanium and engineering plastics like PEEK and Ultem 2300.
