What is CNC Machining?
CNC (Computer Numerical Control) machining is an advanced manufacturing process that precisely controls the movement of machine tools through a computer numerical control system to remove material from a workpiece, creating the desired shape and size.
Compared to traditional manual machining, CNC machining offers higher precision, faster speed, and better repeatability. Through pre-programmed instructions, CNC machines can produce high-quality parts 24 hours a day, ensuring that every product meets strict technical specifications. This automated production method not only improves efficiency but also significantly reduces the possibility of human error.
How CNC Machining Works
CAD Design
Create a 3D model of the part using computer-aided design software, defining all geometric features and dimensional requirements.
CAM Programming
Convert the CAD file into CNC program code, generating tool paths and machining parameters.
Machine Setup
Prepare the CNC machine and corresponding cutting tools, set up workpiece fixtures and coordinate systems.
Machining Execution
Run the CNC program, and the machine automatically performs cutting operations according to the preset path.
