What is CNC Technology?

CNC machining is a metal manufacturing method in which written code controls machines in the production process, and the code has the properties of determining and applying everything from the movement of the cutting head and the part to spindle speed, RPMs, etc. to the machine. CNC machining uses a subtractive manufacturing method in its services. This means that the material is removed during the production process. This advanced technology speeds up production and reduces the margin of error. On the other hand, to better understand this technology, a comparison with 3D printing, which is similar, is provided below.

The Difference Between 3D Printing and CNC Machining

To explain the fundamental difference between the two, we can say that 3D printing performs a type of additive manufacturing. On the other hand, what CNC does is subtractive. This means that CNC machining starts with a block of material (called a blank) and cuts away material to create the finished part. To do this, cutters and spinning tools are used to shape the part. Some of the advantages of CNC machining include high dimensional accuracy, as well as its use in cutting a wide variety of materials.

What Materials Can CNC Be Used On?

Almost any material can be used in a CNC machine. This depends on how the application is carried out. Common materials include metals such as aluminum, brass, copper, steel, and titanium, as well as plastics such as wood, foam, fiberglass, and polypropylene.
