CNC machining materials

CNC Machining in PA

Plastics are another common material used in CNC turning because they are available in many different options, are relatively inexpensive, and have faster machining times. Commonly used plastics include ABS, acrylic, polycarbonate and nylon.

PA (Polyamide) Description

PA, also known as Nylon, is a versatile thermoplastic known for its exceptional strength, toughness and chemical resistance. It is often used in applications requiring strong mechanical properties and long-lasting durability.




Items commonly found in these categories include automotive parts, such as engines, steering wheels, and brakes; electrical connectors for wiring and cables; industrial machinery parts like gears, belts, and bearings; and consumer goods, including appliances, electronics, and household items.


This material is known for its remarkable ability to withstand high levels of mechanical stress. It is also highly resistant to a wide range of chemicals and can withstand harsh conditions and shocks. Furthermore, it retains its shape and size well, exhibiting good dimensional stability.


This material has limited resistance to UV radiation and is prone to moisture absorption, which affects its dimensional stability.

Popular science information about PA

PA (2)

PA (Polyamide), also known as nylon, is a versatile thermoplastic polymer that is widely used in various industries. It is derived from the condensation polymerization of monomers such as adipic acid and hexamethylenediamine. PA is known for its excellent mechanical properties, high strength, and good resistance to wear and abrasion.

PA is commonly used in applications that require high strength and durability, such as automotive parts, electrical connectors, and industrial machinery components. It has good resistance to chemicals, oils, and solvents, making it suitable for use in harsh environments. PA also has good electrical insulation properties and can withstand high temperatures.


PA is available in various grades, with each grade having specific properties. For example, PA6 (Nylon 6) offers good toughness and impact resistance, while PA66 (Nylon 66) offers higher strength and heat resistance. PA12 (Nylon 12) is known for its excellent flexibility and resistance to moisture.
