An angle grinder features a heavy duty abrasive cutting or grinding disc that is powerful enough to cut or grind through steel, concrete and other hard materials. Powered by electricity, compressed air or a battery powered motor, these hard-wearing tools demand that every safety precaution is followed to help prevent injury.

The prospective buyer of a new grinding machine should be aware of the ins and outs of the abrasive process, how abrasive bonds work and the various forms of wheel dressing. This blog post was adapted from an article by Barry Rogers published in the Machine/Shop supplement to November 2018's Modern Machine Shop magazine.

The function of an abrasive wheel is to get rid of the matter from the surface of the work piece. It is covered with abrasives in order to achieve high precision. 10. Coolant The function of the coolant is to reduce the temperature of the work region so that heat cannot be dissolute into the work piece and grinding wheel.

In brief, we can say the working of the Grinding Machine is the Workpiece is fed against the rotating abrasive wheel. The action of rubbing or friction generates between wok price and tool therefore the material removes. Lets see step by step, First, clean the machine with a clean brush. The workpiece is fixed in the worktable.

Abrasive wheel grinder Abrasive wheels and grinding machines come in many styles, sizes, and designs. Both bench-style and pedestal (stand) grinders are commonly found in many industries. These grinders often have either two abrasive wheels or one abrasive wheel and one special-purpose wheel such as a wire brush, buffing wheel, or sandstone wheel.
