CNC grinding (Computer Numerical Controlled grinding) designates a process where an abrasive wheel refines a workpiece by removing small amounts of material. Grinding is made after machining to remove micro inches.

CNC grinding offers more advantages over traditional grinding methods:

• Higher accuracy: CNC grinding offers tight tolerances that can reach ±1µin (±0.025µm).
• More consistent: It is a more consistent process since it is controlled via a computer.
• Higher surface finish: CNC grinding offers smoother surfaces that can reach Ra 2µin 0.05µm 

There are several types of CNC grinding, such as:

1.  Revolving parts : In this process, the workpiece is held in a mandrel and it rotates at high speed. A grinding wheel is then used to remove a thin layer of material while the part is in high rotation. A coolant supply is constantly poured onto the grinding wheel to cool it down. CNC grinding can be used for cylindrical parts, whether centric such as shafts, cylinders, and disks, or eccentric parts, such as crankshafts and camshafts.

Cylindrical grinding can be made for a cylinder's internal and external surfaces.

2. Surface grinding : Surface grinding is used for flat surfaces. The spindle can be mounted horizontally for plane grinding or vertically for grind deburring

3. Thread grinding : It is a grinding process for threads. In this process, a thin grinding wheel is used to polish

4. Gear grinding: Gear grinding is a polishing process for gears. This process is made by using a rotating thin grinding wheel to grind between gear teeth. After grinding each tooth, the gears rotate to grind the next one.
