A Complete Guide to CNC Machining and Custom Parts Production
Computer Numerical Control machining is a precise manufacturing process that uses computer-controlled equipment to create high-precision components from metal, plastic, and other materials. From prototyping to production, CNC machining services are essential in industries like medical, aerospace, and automotive sectors.
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 guided by computer programming (G-code), which allows for consistent, repeatable, and complex production.
Common CNC processes include:
Milling – Versatile and widely used
Turning – Perfect for cylindrical components
Drilling – Accurate hole creation
Grinding – Smooth surface perfection
