Details7.4 Operation Safety – Allow the grinder to "run up" to operating speed before applying it to the job. – Never bump the grinder on to the job, or let the disc hit any other object while grinding. – Keep the grinding disc at a 15 to 30 degree angle to the work. – Make sure the work piece is held firmly in a bench vice, where necessary.
Details6. 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.
