Latest trends in CNC machined materials

CNC machining is a manufacturing process known for its versatility. Manufacturers use this process to create high-quality, custom-designed parts and products from virtually any type of material for a variety of industries. Typical machining materials include metal, plastic, wood, foam and fiberglass.

Types of processing materials

Given the wide range of applicable materials, CNC machining provides customers with greater flexibility in designing and engineering their parts and products. Although aluminum is the most commonly used material in CNC machining operations, almost any material with sufficient hardness can be CNC machined, including:

Alloys and tool steels (eg 4140, 4340, D2, A2, O1): Wide range and varying performance

Aluminum 6061: aviation grade, affordable and easy to process

Brass C360: Excellent processability and surface finish

Double sides (eg 303, 17-4): high yield strength

Low carbon steel (eg 1018, 1045, A36): similar performance to SS 304, but more economical

Stainless steel (e.g. 304, 316, 2205): corrosion and chemical resistant

Nitrile butadiene styrene (ABS): toughness and impact resistance

High density polyethylene (HDPE): high strength density ratio

Nylon 6: Abrasion and chemical resistance

PEEK: high mechanical and chemical resistance

Polycarbonate (PC): Robust and easy to process

Delrin: Designed for large mechanical loads

Teflon: hydrophobic and low coefficient of friction

To process these materials, the CNC machining process uses pre-programmed software to guide the movement of tools and machinery (including grinders, lathes, milling machines, and router planers) to create complex designs and shapes. In contrast, manual processes require the direct involvement of the operator to initiate and direct operations. In addition, CNC machines can handle many different operations such as wiring, milling, drilling, coil winding, terminal positioning and soldering.

CNC parts for various applications

CNC machining is the main content of the entire manufacturing process. From small machining shops to large manufacturing plants, this process can be used to make precise parts without the risk of human error. Industries that rely on CNC machining to produce the necessary parts include:

Aerospace: Doors and body components Agriculture: farm equipment Automotive: Precision holes for frame assembly Construction: Heavy Equipment Parts Dentistry: dental equipment and tools Electrical and electronic trumpet: small, precision electronic components Lettering and sculpting: sculpting tools and sculpting

Firearms: Precision gun components Hospitality: signs and decorations Manufacturing: precision parts such as rollers Metal products: high contact tools Military: Precision parts and tools for transportation and assembly Production: Conveyor rollers and gears Transportation: precise control components
