The grinding wheel is a cutting tool. It's an abrasive cutting tool. In a grinding wheel, the abrasive performs the same function as the teeth in a saw. But unlike a saw, which has teeth only on its edge, the grinding wheel has abrasive grains distributed throughout the wheel. Thousands of these
The 3M™ Silver Depressed Center Grinding Wheel is a type 27 wheel designed to deliver an unbeatable combination of performance and value. This long-lasting wheel uses 3M Precision-Shaped Grains to deliver a fast and consistent cut during grinding and heavy stock removal on stainless steel, mild steel, aerospace alloys and more.
Background: This grinding wheel was part of a product liability and personnel injury case. It was claimed that the subject wheel had unexpectedly failed (i.e. flown apart) and an escaping piece had hit the plaintiff in the face causing serious injuries.
Performance characteristics. Assuming a grinding process has been developed that results predominantly in micro-fracture of CBN grains, common and predictable wheel performance trends are often observed with single-layer wheels.

1979-01-30· A grinding wheel is provided around the inside of its hole with a plurality of turns of an electrical conductor weaker in tension than the material of the wheel, the ends of which are brought out to terminals on the surface of the wheel.
Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. The grinding process itself ...
Grinding Wheel Condition Prediction and Improvement Ping Zhang, Michele H. Miller Michigan Technological University, Houghton, MI Introduction Grinding is regarded as a good way to do ceramics machining due to its multiple abrasive cutting particles. While a single point tool may dull and require re-sharpening, a grinding wheel distributes wear over many cutters and is capable of replenishing ...
The nature and extent of grinding wheel wear in precision grinding were investigated directly from the wear particles removed from the wheel. A statistical analysis of the wear particle size distributions was developed to determine the relative amounts of bond fracture, grain fracture, and attritious wear.
Grinding wheels are safe tools when they are used in accordance with some basic rules. However if they are used incorrectly or not installed carefully onto the machine, there is the possibility that the grinding wheel may fracture.
An investigation of attritious and fracture wear of grinding wheels in precision grinding is described in a two paper sequence. Attritious wear, the subject of this first paper, refers to the dulling of the abrasive grain due to rubbing against the workpiece surface.
Evidence is presented which supports the argument that the fracture type of wear process is the most important with regard to the loss of abrasive material from a wheel during a grinding operation and that fracture occurs as a consequence of the high stresses induced in the grains by the grinding forces to which they are subjected.
