What Is Custom CNC Machining? Process, Materials & Applications for Precision Parts
CNC machining workshop equipment
Custom CNC machining has become the most popular manufacturing method for producing high‑precision metal and plastic components used in global industries today. More and more engineers and procurement buyers choose custom CNC machined parts for their strict tolerance requirements, complex shapes and stable quality.
What is CNC Machining?
CNC (Computer Numerical Control) machining is a subtractive manufacturing process that uses computer‑controlled cutting tools to remove material from a solid workpiece. The two most common CNC processes are CNC turning and CNC milling.
- CNC Turning: Ideal for round, cylindrical parts such as shafts, bolts, sleeves and pins.
- CNC Milling: Suitable for complex flat, 3D‑shaped parts with holes, slots and irregular structures.
With modern CNC equipment, we can achieve precision tolerances as tight as ±0.005mm, meeting strict standards for medical, automotive, electronics and automation equipment.
Common Materials for Custom CNC Machined Parts
We mainly process widely‑used industrial materials for global customers:
- Aluminum (6061, 7075): Lightweight, good corrosion resistance, easy to machine, widely used in electronics and automation.
- Stainless Steel (304, 316): High strength, rust‑proof, perfect for medical and mechanical parts.
- Brass & Copper: Good conductivity, used for electrical and precision connector parts.
- Engineering Plastics: POM, PEEK, Nylon for lightweight non‑metal components.
