What is the main difference between CNC milling and CNC turning?

Did you know that sheet metal services include many different processes? For this manufacturing technique, you can use the forming process, but you can also use cutting or joining methods. For CNC machining services, it is actually the same. In fact, CNC machining is a general term for several different processes. This includes CNC milling and CNC turning. Both technologies are completed with the help of a 3-axis CNC system and are regarded as basic machines. Both allow the cutting tool to move along three linear axes relative to the workpiece. Essentially, this means front and back, left and right, and up and down. However, there is also a big difference between CNC milling and CNC turning, as shown below.

CNC  milling and  turning
CNC milling is a three-axis machine tool, as described below. This places some restrictions on the geometry of the part, but it is still sufficient for most jobs that require milling. This can be done with the help of many different milling tools, as well as different methods. However, you can also use multi-axis milling. This allows 4 or more axes. It includes the rotation of tools and worktables, which brings additional flexibility. Usually a 5-axis milling machine for this application. Basically, all these machines can be milled and manufactured.
CNC turning or CNC lathes are done by holding the workpiece on the spindle while rotating at high speed. The cutting tool will track the inner or outer circumference of the workpiece to form a geometric shape. The tool does not rotate, but moves in the polar coordinate direction. This is done in the radial and longitudinal directions. CNC lathes are widely used because they can produce parts at high speeds, while the cost per unit is still low. Of course, for larger quantities, this is perfect. Five-axis milling and turning CNC machines can also be used for this application.
In fact, the difference between CNC milling and CNC turning can be easily explained. The answer to this question is short: CNC milling uses rotating tools, while CNC turning uses rotating parts for cutting. Therefore, both processes use different techniques to create parts.
