Surface grinding - Wikipedia
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.

pedestal grinding ended
A bench grinder is a benchtop type of grinding machine used to drive abrasive wheels. A pedestal grinder is a similar or larger version of grinder that is mounted on a pedestal, which may be bolted to the floor or may sit on rubber feet. These types of grinders are commonly used to hand grind various cutting tools and perform other rough grinding.

THE REEL ANSWER TO SPIN-GRINDING
Spin grind creates a more accurate diameter control of the reel. A properly spun-ground reel should not need backlapping. Relief cylinder grind: For a cylinder grind with relief angle, grinding machines have evolved to a point where you can spin-grind the diameter. As a second step, relief-grind while the reel remains set up in the position used

The Working Principle of Milling Machines
The average uncut thickness can be taken as half of the maximum value. Thus, From the above equation show that when the depth of cut increases, the chip thickness increases so that increases the cutting resistance and the amplitude of vibrations. As a result, cutting temperature also rises.
