The main purpose of blotters is to distribute the clamping force of the flanges evenly on the wheel, but they also prevent slipping at lower clamping forces and reduce wear on flanges. Blotters should be an easy fit on the spindle or on the wheel locating spigot, if there is one, and should be slightly larger than the flanges.

The main reason crankshaft grinding is done is because the crank wears over time. Over thousands miles the end play between the crankshaft and the bearings increases. When the "fit" between the bearings and the crank isn't perfect it lowers oil pressure and decreases lubricity. The less oil to the crank the faster it can wear out.

Specification of grinding wheel: Grinding wheel is the main component of the grinding machine. It is responsible for the whole machining process. The proper selection of grinding wheel is very important and the selection of the grinding wheel depends on various factors such as a material of the work piece, finishing requirements etc.

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

The main purpose of grinding is of course to remove material to specified dimensions. However, a large amount of the energy can rise the temperature up to 1500°C in the surface layer. This heat energy must be transported away by cooling effectively.
