There are different types of CNC turning processes, let us look at them here:

Hard Turning: This type of turning is used for heat treated materials which have Rockwell C hardness of more than 45. Injection pump components, gears, and hydraulic components are some examples where this type of hard turning process is commonly used.

Tapered Turning: Here hydraulic copy attachment, form tool, or a CNC lathe is used to perform such tapered turning. It is considered a suitable method in case work is to be performed on shallow tapers.

Spherical Generation: In case of spherical generation any specific form is generated using a fixed axis of revolution.

Facing: In this process cutting tool faces rotating work piece at right angle. Normally, during production of any work piece, it is the first or the last operation that is undertaken.

Parting: This method is used for separating smaller parts out of a larger block.

Grooving: It involves cutting grooves of specific depth on external as well as internal surface of the material.

Knurling: This process can be utilized for creating hand grip on surface of the material.

Reaming: Reaming is used for removing very small amount of material out of a hole that has already been drilled. The aim here is to create internal holes with accurate diameters.
