Suspend the wheel on a pin or hangar. Large wheels can be stood on edge on a clean, hard surface. Using a light, nonmetallic implement (a screwdriver handle does a fine job), gently tap the wheel 1 to 2 inches from the periphery and 45 degrees to either side of the wheel's vertical centerline. Rotate the wheel 45 degrees and test again.
Ring or disc grinding wheels are mounted (bolted or cemented) to a backing plate, which drives the wheel. Superabrasive type 2A2 wheels fall into this category. Conventional bonded abrasive type 35, 36 and 37 fit into this category. Straight Cup. Cups have a cup, bowl or double cup shape.

Operators can't be too careful in selecting abrasives for these tools. A typical straight-shaft grinding tool has a maximum speed of 1,600 RPM; Fein's MSh 635 die grinder achieves 48,000 RPM. This is a speed differential of 30-to-1. Any tool intended for a maximum of 1,600 RPM would likely disintegrate at 48,000 RPM, and injuries could result.

Polishing processes involve loose abrasives which roll over the surface. This is gentler and leads to a better surface finish but also yields lower removal rates. Metallographic polishing eliminates any remaining roughness from the grinding process, ensuring a good surface finish for further examination.
Meister Abrasives diamond grinding tools are used for the grinding of wafers and for dicing the wafers. With excellent TTV values, surface qualities in the one digit Angstrom range are achieved.

wheel immediately before mounting it. Make sure that the wheel is clean and dry before you begin the test. The Ring Test The ring test assesses the sound coming from a grinding wheel when it is lightly tapped. An undamaged wheel sends out a clear ringing tone. Use this test on vitrified bonded wheels. Do not use it on:
Rubber-Cushioned Abrasive GrindingBits without Shank for Metals. Bits thread onto mounted shanks so you can quickly switch head shapes without removing the shank. The abrasive grains are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits.
