1. What is CNC Machining?
CNC machining is a subtractive manufacturing process where pre-programmed computer software controls the movement of machinery and tools. It is used to produce high-precision parts from materials like metals, plastics, and composites.
Key CNC Machining Processes
Milling – Rotating cutting tools remove material from a workpiece.
Turning – The workpiece rotates while a cutting tool shapes it.
Drilling – Creates precise holes in materials.
Grinding – Achieves ultra-fine surface finishes.
EDM (Electrical Discharge Machining) – Uses electrical sparks to shape hard metals.
China’s CNC machining industry excels in all these processes, offering unmatched precision and efficiency.
