CNC Precision Machining Methods
CNC Milling and Turning
CNC precision machining primarily employs two methods to manufacture parts: CNC milling and CNC turning. Both can achieve high-precision machining of parts. CNC milling uses a rotary cutting tool for cutting and shaping, making it ideal for machining complex three-dimensional shapes, molds, and special fixtures. CNC turning, on the other hand, rotates the material while the cutting tool is cutting, making it best suited for machining round parts such as shafts and bolts. CNC milling and CNC turning play important roles in fields such as aerospace, automotive, and medical devices.
| CNC Milling | CNC Turning |
|---|---|
| Used for making hard 3D shapes, molds, dies, and special holders. | Mostly used for making round parts like shafts and bolts. |
| Common in aerospace for big parts and in cars for test pieces. | Often used in oil and gas for valve parts and in medical devices for implants. |
| Can make flat and odd shapes easily. | Cheaper for round parts and removes material faster. |
KEMING uses new cnc precision machining for both cnc milling and cnc turning. Their team uses special machines to make sure every part is just right.
EDM and Other Techniques
Electrical discharge machining, called EDM, is another key way in cnc precision machining. EDM uses sparks to shape hard materials. The tool does not touch the part. EDM is great for making sharp inside corners and tricky molds. It is slower than cnc milling and cnc turning. But EDM can make shapes that other ways cannot.
| Feature | EDM | CNC Machining |
|---|---|---|
| Process Type | Does not touch the part | Tool touches the part |
| Material Capability | Best for hard materials | Works on many materials |
| Speed | Slower | Faster |
| Complexity of Shapes | Makes hard inside shapes | Tool shape limits what it can make |
| Best Use Case | Sharp corners, tricky molds | Normal materials, test pieces |
EDM is best for parts made from hard tool steel. It is needed for sharp corners in dies and for making deep holes in molds. Cnc machining is faster for most jobs. But EDM is needed for very detailed shapes.
