Bench and Tool Grinders (Ellis Dunklebarger)

Grinders

Grinders are used to abrade away material with abrasive disks and brushes. The most common forms are the bench and angle grinders. For grinding surfaces to be very precise and smooth, there are also surface and cylindrical grinders that have grinding wheels held in precision stages and the part is moved via an automatic feed mechanism.

Use

Grinder use is very easy, just be sure your hands cannot slip into the wheel in any way. Take care to keep the part cool and not use excessive pressure.

Safety Precautions

Protective eyewear, hearing, respiratory protection, and clothing should be worn. The grinder produces high temperature, high speed, flying bits of metal that you do not want in your eyes, lungs, or skin. Never stand in front of the grinding wheel, but off to the side. Grinding wheels are very brittle and will at some point fail, especially if there is a small defect due to an impact. The exploding wheel will hurl high velocity chunks that can easily penetrate the body.
