Grinder Safety – Ring-Testing. OSHA requires that grinding wheels be ring tested before mounting them. This simple step prevents the inadvertent mounting of a cracked grinding wheel. Ring-Testing involves suspending the grinding wheel by its center hole, then tapping the side of the wheel with a non-metallic object.

Safeguarding Standards for Bench and Pedestal Grinders Grinders are one of the most frequently cited machines during OSHA machine-safety inspections. This is frequently due to improperly adjusted work-rests and tongue-guards on bench/pedestal grinders, as well as a lack of ring-testing for the grinding wheels. OSHA 29 CFR SubPart O 1910.215 is a "machine specific" …
5. Move the grinding wheel down using the vertical table handwheel until it barely makes contact with the dresser. 6. Turn the machine off after making contact with the dresser. 7. Turn the machine on again. While the wheel is spinning, lower the grinding wheel down in the Z direction until it makes a small plume of dust. 8.
Check grinding wheels for cracks (Ring Test Figure 5-11) before mounting. Never operate grinding wheels at speeds in excess of the recommended speed. Never adjust the workpiece or work mounting devices when the machine is operating Do not exceed recommended depth of cut for the grinding wheel or machine. Remove workpiece from grinding wheel ...

Non-safety related markings found on grinding wheels are: The manufacturer's trademark/name. The test record number, indicating it meets the standards for safety. The expiry date if it's an organic bonded wheel (this will be 3 years from the date of manufacture). What is the trouble when grinding wheel fails to cut in a grinding machine?
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.

Here is our list of DO's and DON'Ts when it comes to grinding wheels. DOs for grinding wheel safety. DO check all wheels for cracks or other damage before mounting. DO make sure the machine speed does not exceed the maximum operating speed marked on the wheel. DO use an ANSI B7.1 wheel guard. Position it so it protects the operator.
Products like grinding wheels and centrifuge components are hazardous if they fly apart in use because of centrifugal forces. To guard against that happening, the designs for such products are routinely tested by spinning them at high speeds until they burst. A well-known manufacturer of spin-testing equipment came to us with a design problem. When
Turn the wheel 180 degrees so that the bottom of the wheel is now on top. Tap the wheel about 45 degrees on each side of the vertical line again. The wheel passes the test if it gives a clear metallic tone when tapped at all four points. If the wheel sounds dead at any of the four points, it is cracked. Do not use it.
Grinding Wheel is generally composed of two types of materials. One is the abrasive cutting compound used for grinding in Industrial applications. The other is the bond formed between the abrasives. A grinding wheel performs several operations in the grinding and the abrasive machining. Grinding wheels are used in grinding machines.

Ring test and visually inspect all grinding wheels before they are mounted. [FED/OSHA 1910.215, CAL/OSHA §3580] Verify that the maximum RPM rating of each abrasive wheel meets or exceeds the grinder RPM. [FED/OSHA 1910.215(d)(1), CAL/OSHA §3583] Use approved lockout/tagout means and procedures for all maintenance activities.
One method of grinding wheel inspection is called ring testing. OSHA, ANSI and the grinding wheel manufacturers require this method of grinding wheel inspection. It must be performed BEFORE the wheel is mounted on a grinding machine.
When you need to put a new wheel on your grinder, what should you do with the wheel first? A) Nothing. If it's a new wheel, straight out of its packaging, just put it right on the grinder. B) Give it a 'ring test' to make sure it is suitable for use. C) Prepare it for use by soaking it in water for no less than three minutes.

Rotate the wheel 45 degrees and test again. Each tap should produce a clear ringing sound like that of a bell. Cracked wheels will emanate a dull thud and should be disposed of immediately. These steps are outlined in OSHA standard 1910.215 and most grinding wheel manufacturers' websites.
A grinding wheel's durability comes from its bonded construction. 3M Grinding Wheels are built by bonding abrasive grain together with resin to create a hard, durable wheel. This construction makes an abrasive wheel that lasts longer than other metal grinding solutions like flap discs and fibre discs, reducing the amount of time spent ...
The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
Creep-feed-grinding aerospace nickel alloys: 10 to 20 mm 3 /mm/s; Flute grinding of taps with resin bonded wheels: 10 to 20 mm 3 /mm/s; Flute grinding solid carbide mills: 6 to 12 mm 3 /mm/s; These values depend on the stiffness of the machine tool, the fixturing of the workpiece, the hardness and the microstructure of the material to be ground.
One method of grinding wheel inspection is called ring testing. OSHA, ANSI and the grinding wheel manufacturers require this method of grinding wheel inspection. It must be performed BEFORE the wheel is mounted on a grinding machine.
