A Complete Guide to CNC Machining and Custom Parts Production
Computer Numerical Control machining is a modern manufacturing process that uses automated tools to create high-precision components from metal, plastic, and other materials. Whether you're developing prototypes or mass-producing end-use parts, CNC machining services are critical in industries like automotive, aerospace, and medical devices.
This article will break down everything about custom CNC machining, from its benefits and applications to choosing the right supplier or factory—with a focus on capabilities available in China-based CNC machining providers.
What is CNC Machining?
CNC (Computer Numerical Control) machining is a subtractive manufacturing method in which material is removed from a solid block using various cutting tools. The entire process is automated by computer programming (G-code), which allows for precise, intricate, and scalable production.
Common CNC processes include:
Milling – Ideal for complex surfaces and holes
Turning – Efficient for rotational symmetry
Drilling – Accurate hole creation
Grinding – Smooth surface perfection
