6. Precision Grinder. 3. Wrapping It Up. Machines in which grinding wheels are fitted and grinding is done, such machines are called grinding machines. On the basis of their function, they can be divided into two parts. Ordinary grinding machines are widely used. These are called rough or snagging grinders.
