Select Right CNC Machining
CNC is short stands for “Computer numerical control”. So all the processes numerically controlled could be called CNC machining including even 3D printing.
CNC machines in a broad sense
- Plasma cutters
- Water jet cutters
- Laser cutting
- 3D printing
- Embroidery machines
- Canned cycle
- Sheet metal punch
- Tube, wire bending machines
But as 3D printing and some other processes have their exact name, CNC often represent the subtractive processes of CNC machining, such as CNC milling, drilling, routing, turning, grinding, etc
2-3x cost gap
The Right Way to Save Money
The real way to save money is by selecting the right CNC process based on the tolerance that can reach your requirement. The CNC machining process is relatively expensive even with a big gap between different CNC processes, E.G. CNC milling vs CNC router
CNC milling vs CNC router
We have designed an RFID desktop used for reading RFID tags. The part is made of clear acrylic with a pattern printed on the back. For a rectangular part, it can be manufactured both by CNC milling and CNC router plus post-polishing, with the price being 2.5: 1. Because the CNC milling can achieve a tight tolerance to ±0.0025mm. The CNC machinery and operator require more payment. The CNC router is less power suitable for plastic materials with normal tolerance of about ±0.13mm. So For complex shapes or surfaces that are impossible to polish by an NC machine or manually, CNC milling is the right choice
CNC machining is widely used in custom manufacturing, for parts, prototypes, and molds. As the cost makes a big difference we mentioned above, it is important to determine the material, tolerance, and process. You can send us a sample, or tell us what it’s used for, CADmize engineer would help you make a better decision.
