How far should the tool rest be from the grinding stone?

The tool rest must be minimally within  of an inch of the grinding wheel. If a magnetic chuck is being used on the surface grinder, make sure it is holding the work securely before starting to grind. Prior to starting the grinder, ensure the tang at the top of the wheel opening is located within -inch of the wheel.

What is the maximum safe air gap between the tool rest and stone on a bench grinder?

What should the gap between the tool rest and the grindstone on a bench grinder never be more than? 3 mm (1/8″).

What is the safe distance between the grinding wheel and wheel rest?

The gap should be no more than 3mm as a bigger clearance could cause the tool to become jammed in between. no less than 3mm so that debris also doesn’t cause the grindstone to jam.

How far should the tool rest be set from the grinding wheel when grinding?

1/16th of an inch
Always keep the tool rest the correct distance from the wheel, usually 1/16th of an inch (1.5 mm). As the wheel is ground down the tool rest needs to be reset. Be especially careful when grinding edges, corners, ragged joins and so on.

How much of a gap should there be between the work rest and the face of the grinding wheel?

one-eighth of an inch
Next, make certain the lower work rest, also known as a tool rest, is installed when using an abrasive wheel, and that it is adjusted so the gap between the face of the grinding wheel and tool rest is not more than one-eighth of an inch (refer trainees to the handout accompanying this toolbox talk).

What is the recommended gap between tool post and grinding wheel?

A nozzle is used to inject the electrolyte into the gap between wheel and electrode. The gap is usually maintained to be approximately 0.1mm to 0.3 mm.

What is the correct distance of the tool rest from the grinder wheel or disc sander?

What is the maximum distance that a work rest should be from the wheel face?

one-eighth inch
Work rests shall be kept adjusted closely to the wheel with a maximum opening of one-eighth inch to prevent the work from being jammed between the wheel and the rest, which may cause wheel breakage.

What is grit size in grinding wheel?

Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit). Superfine grits run from 150 and higher. Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher.
