Bench Grinders

Bench grinders must be equipped with a tool rest set above the centre line and within 3 mm of the wheel.  The wheel surface will be routinely cleaned to ensure it is kept flat.  Do not use the side of a grinding stone.  It is not designed for this stress.

Check the tool rest for the correct distance from the abrasive wheel, maximum 3mm from the face of the wheel.

Replace the grindstone when adjustment of the rest cannot provide 3mm clearance.

If the wheel has been abused and ground to an angle or grooved, reface the wheel with the appropriate surfacing tool.

Protect your eyes with goggles or a face shield at all times when grinding

Each time a grinding wheel is mounted, the maximum approved speed stamped on the wheel bladder should be checked against the shaft rotation speed of the machine to ensure the safe peripheral speed is not exceeded. A grinding wheel must not be operated at peripheral speed exceeding the manufacturer’s recommendations.

The flanges supporting the grinding wheel should be a maximum of 1/3 the diameter of the wheel, and must fit the shaft rotating speed according to the manufacturer’s recommendation.

Bench grinders are designed for peripheral grinding.  Do not grind on the side of the wheel.

Do not stand directly in front of grinding wheel when it is first started.

Occupational Health and Safety must be notified if a grindstone or grinding wheel bursts.  (See “dangerous Occurrences” under OH&S Regulations)
