Resinoid grinding" refers to a type of grinding process that utilizes a grinding wheel bonded with a resin material, known as a "resinoid bond," which holds the abrasive grains together, allowing for efficient cutting and smooth surface finishes, particularly suitable for high-speed applications and materials that generate heat during machining. Resinoid grinding wheels are often used for applications where high-speed cutting, smooth finishes, and minimal heat generation are required, such as on metals, plastics, and composites.

A type of innovation with the grinding wheels, the crankshaft grinding wheels finds its usage in the different automotive, truck, diesel, aircraft, and small engine manufacturing industry and also in the various engine rebuilding firms that are used to regrind the pins and the bearings. Grinding Machines that involve the usage of crankshaft grinding wheels are generally run at a very high speed of 2700m/min; however, some production machines can run at higher speeds as well. The thickness of the crankshaft wheels depends on it’s the type of machine in which it has to be used.
The good quality crank grinding wheels can be used to hold the corner radii tight and so provides amazing surface finishes of pins, bearing sets and then the side walls of the crankshaft with the plunge grinding
