What Is CNC Machining?
CNC Milling

It is an operation where the cutting tool rotates. When the milling tool comes into contact with the workpiece, it removes chips from it.
Milling operations include:
- End milling
- Chamfer milling
- Face milling
- Drilling, boring, tapping, etc.
It is a very universal fabrication method with great accuracy and tolerances. Milling is suitable for a variety of materials and is also very quick. The ability to manufacture a wide range of complex parts is a great advantage.
The disadvantages include a large amount of waste, need for a variety of tooling and high cost of equipment.
CNC Turning

While the two are often called just CNC machining, turning and milling have distinct differences. Turning, or lathing is pretty much the opposite of milling. This means that instead of the cutting tool, the workpiece is rotating.
A CNC lathe is commonly used for producing shafts, for example. The tool is brought against the rotating workpiece to cut off bits of metal, known as chips or swarf.
Turning is usable on the outside of a cylinder or on the inside. The latter operation is called boring.
CNC Grinding

.
CNC Routing

A CNC router is similar to a CNC mill. It comes with the ability to use computer numerical control to route tool paths that enable the machine to function. CNC routers reduce waste and increase productivity, producing various items in a much shorter amount of time than using other machines.
CNC Drilling

In order to be cost-effective, the appropriate type of CNC drilling machine needs to be applied to a particular part geometry. For low-volume jobs, manual or semi-automated drilling may suffice. For hole patterns with large differences in sizes and high volume, a geared head is most appropriate. If holes are close to each other and high throughput is desired, a gearless head can locate spindles close together so that the hole pattern can be completed in one pass.
