For the need to replace the bench grinder grinding wheels.
Aluminum Oxide Grinding Wheel
- Do always handle and store grinding wheels in a careful manner. Most bench grinding wheels are vitrified/glass bonded products and are very strong, but brittle.
- Do visually check all wheels for cracks or damage before use. In addition to the visual inspection, “Ring Test” all wheels before mounting on the bench grinder.
- Do check machine speed against established safe operating speed marked on the wheel.
- Do use mounting blotters as supplied by the wheel manufacturer.
- Do inspect mounting flanges for equal size, relief around the wheel’s hole, and the correct diameter. Flange diameter must be equal to or greater than one-third the wheel’s diameter (e.g. 6 inch wheel, 2 inch flange).
- Do use flanges that are clean, flat, and smooth.
- Do make sure the bench grinder has the proper wheel guard. Bench grinder guards should have side guards that cover the spindle, end nut, and flanges. It must cover 75% of the wheel’s diameter.
- 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 the rotating grinding wheels during this test because, if damaged, the wheel most likely will break during this test.
- Do keep your work area clean and free of anything that could accidently strike or make contact with the grinding wheel.
- Do turn off coolant (when used) before stopping the grinding wheel to avoid creating an out of balance condition on the wheel.
- Do wear proper personal protection such as eye and face protection, apron, gloves, safety shoes, etc.
- Do maintain your tools as if your life depends on it.
- Do grind on the wheel’s face (outer diameter) only. Side grinding is NOT allowed.
- Do keep your grinding wheel face open and free of metal build-up. Dress wheel to remove foreign metals and to open the wheel face with new sharp abrasive grains.
- Do make sure your bench and pedestal grinder is permanently mounted. It should not move or fall over during use.
- Do review all applicable MSDS (Material Safety Data Sheets) before using this product.
- When required, control dust.
- Do comply with ANSI B7.1, OSHA and all safety materials provided with the wheels and the grinders.
- Do visit the abrasive manufacturer’s website for additional safety information.
- Do contact your abrasive manufacturer if you have any safety questions.
- Don’t use wheels that have been dropped or otherwise damaged. If the wheel does not pass a “Ring Test”, do not use it.
- Don’t force a wheel onto the machine or alter the size of the wheel’s mounting hole. If the wheel won’t fit the machine, get one that will fit properly.
- Don’t exceed the speed marked on the grinding wheel.
- Don’t use mounting flanges on which the bearing surfaces are not clean, flat, and smooth.
- Don’t tighten the mounting nut excessively. Tighten the nut just enough to prevent wheel slippage.
- Don’t start the machine until the safety guard is properly and securely in place.
- Don’t adjust the work rest or tongue guard/spark arrestor while the grinding wheel is rotating.
- Don’t stand in front of or in line with a grinding wheel whenever a bench grinding machine is started.
- Don’t grind on the side of the wheel.
- Don’t jam the work into the wheel.
- Don’t grind material for which the wheel is not designed. Do not grind/sand wood, plastic, or any other non-metallic materials.
- Don’t use this wheel if you have not reviewed all of the safety materials and have not been properly trained in the use of the tool and wheel.
