Just like sandpaper is used to sand wood or stone, a grinder is a specialized sanding tool in the manufacturing industry. Its main task is to ensure that parts are manufactured to a superior level of surface quality and accuracy, which is comparable to performing microsurgery on a product to refine its appearance. This makes grinding machines an indispensable part of the manufacturing industry, providing critical support for the quality of the final product.

Grinding wheel grinding is one of the common processing methods in the manufacturing industry, and the roughness of the workpiece produced in the process directly affects the quality and performance of the product. The factors that affect the roughness of grinding wheel grinding workpiece include both the wheel itself, including other factors.

Among all the grinding machines, cylindrical grinding machine is a widely used type of machine tool, which is mainly used for precision grinding of end face, external circle and conical surface of batches of shaft parts, and it is the main equipment for automobile engine and other industries. Can be divided into ordinary cylindrical grinder, universal cylindrical grinder, end face cylindrical grinder and other types.

Factors affecting surface roughness of grinding machine processing and its improvement measures:
The finer the grain size of the grinding wheel, the more abrasive grains per unit area of the wheel, the finer the grinding surface scars, the smaller the surface roughness value. However, if the grain size is too fine, the grinding wheel is easy to be clogged, so that the surface roughness value increases, and at the same time, it is also easy to produce ripples and cause burns.
The hardness of the grinding wheel refers to the ease with which the abrasive grains can be dislodged from the wheel after being subjected to the grinding force. Grinding wheel is too hard, abrasive wear can not be dislodged, so that the surface of the workpiece is subjected to strong friction and extrusion, increased plastic deformation, surface roughness value increases, but also easy to cause burns; grinding wheel is too soft, abrasive grains are easy to dislodge, the grinding effect is weakened, but also increase the surface roughness value, so choose the appropriate grinding wheel hardness.

Grinding is a processing method that removes the excess layer on the surface of the workpiece with the help of the cutting action of the abrasive tool, so that the surface quality of the workpiece meets the predetermined requirements. Grinding is a very widely used processing method in machinery manufacturing, which uses abrasives as tools to carry out cutting processing on the grinding machine. The machining accuracy can be up to IT6 ~ IT4 level, surface roughness Ra value of 1.25 ~ 0.01 μm. can also complete other machine tools difficult to process materials, such as hardened steel, carbide, glass, ceramics and other processing.

It is not difficult to process steps with a surface grinder. It should be noted that the steps can be ground from two directions, the choice of which face to cu
