In addition to Speed Testing and Balance Testing your grinding wheels, Mach-B performs Ring Testing on every wheel that passes through our shop.. Ring testing is a manual test that is used to detect defects in bonded grinding wheels. A wheel that emits a ringing sound when lightly tapped with a tool is likely undamaged and ready to be used.
How to "ring test" a grinding wheel. Grinding wheels must be inspected and "ring-tested" before they are mounted to ensure that they are free from cracks or other defects. Wheels should be tapped gently with a light, nonmetallic instrument. A stable and undamaged wheel will give a clear metallic tone or "ring."
The daily grind: Test your knowledge on grinder safety. MANCOMM. A worker steps up to an abrasive wheel grinder and places a piece of metal against the wheel's spinning surface. But because the machine was not adjusted correctly, the metal catches in the grinder. A split-second later, the grinding wheel explodes, sending stony chunks, as ...
Grinding wheel diameter. Increasing the diameter causes the grinding wheel to act harder, because the expanded contact area distributes the stock removal over a larger number of grains, thus reducing the specific force expended on each individual grain. Peripheral speed of the grinding wheel.
Before mounting a vitrified wheel, ring test it as explained in the American National Standards Institute's B7.1 Safety Code for the Use, Care and Protection of Grinding Wheels. The ring test is designed to detect any cracks in a wheel. Never use a cracked wheel.
