Machine category
CNC used to use two kind of Machine to produce and each of the advantage as below.
Of course both of their accuracy can be in ±0.02mm even in ±0.01mm.
| CNC machine type | Horizontal Machine | Vertical Machine |
| Principle | Auto feeding | Muti-direction to process |
| Suitable product | Circle, Cylinder Small component |
Complex , Irregular shape Big component |
| Benefit | Save time and money (Cheaper) | Process can do most Complex |
1. Horizontal Machine
2. Vertical Machine
CNC’s value for you
1.Freedom of Design
2.Precisely size especially in wearable device
3.Smooth and beautiful
4.Because CNC doesn’t need mold , it’s economical when your demand under 5000 pcs. You can save money.
Note
In summary.
If you want to start a project, you have to find out which process, supplier, machine that meet your need.
When you choose the correct process, way and machine, you can not only save your money but improve your quality.
