grinding wheels are manufactured to operate safely up to a maximum rotational speed (rpm). standard bench and pedestal grinders are available with rpms between 900 and 3,600 rpm and grinding wheels are available maximum rpm ratings between 1,200 and 5,000 rpm. the centrifugal force of a rotating disc is related to its speed squared.
grinding wheels dull and/or load up with material between the grains regularly, and dressing is a required step when they do. bench/pedestal grinders are often used by laymen who are not familiar with the process of dressing a wheel.
do make sure your bench grinder has an adjustable work rest that is kept adjusted to 1/8 inch or less from the wheel’s grinding face. do make sure your bench grinder has an adjustable tongue guard/spark arrestor and set it to ¼ inch or less from the wheel’s grinding face. do allow newly mounted wheels to run at operating speed for one minute before grinding. do not stand in front of or in line with
