In recent years, the pass rate of grinding products has been low, and there are various problems that cannot be ignored. Some problems have seriously threatened the safety of personal property.

The grinding wheel is a complex system composed of a variety of main and auxiliary raw materials. The main materials are abrasives and binders. The auxiliary materials include fillers and reinforcing materials. The future industry will continue to develop harder, higher strength and more. Lighter and more tough workpiece materials to minimize part weight and increase part life. In order to use superabrasives, the grinding machine and machining center have been significantly improved. CNC control systems, automatic loading and unloading, complex on-line measurements, high-speed spindles, and enclosed high-pressure/high-capacity coolant supply units are all designed to maximize the benefits of using superabrasives. Regular dressing allows the grinding wheel to maintain good grinding performance and correct geometry, avoiding passivation, blockage and distortion of the grinding wheel. The commonly used dressing tool is a diamond pen. Therefore, the roller technology is not only applied in the aerospace and aviation advanced fields, but also has wide application value in ordinary civil production.

In the grinding wheel, the abrasive particles are bonded together by the bonding agent, and the performance of the bonding agent directly affects the performance and quality of the grinding wheel. One of the characteristics of the grinding wheel manufacturing is that the process is very strong, and any omissions and deviations in the manufacturing process may have a negative impact on the quality of the grinding wheel product. With new materials, some components such as camshafts, crankshafts, wheels, brakes and supports can now be pressed or forged and then finished with high-speed grinding or high-speed machining. This can significantly reduce the time from blank material to finished parts.

At the same time, the graphite workpiece is cut into the graphite blade at the same time, the cutting edge is the longest, the cutting resistance is the largest, and the cutting force of the tool is the largest, so the tool wear, milling force and cutting vibration are the largest. When the helix angle is large, the direction of the milling force is larger than the surface of the workpiece, and the cutting impact caused by the collapse of the graphite material is intensified, so that the tool wear, the milling force and the cutting vibration are also increased. Since the wear of the diamond tool is closely related to its load state, the processing conditions have a significant effect on wear.

After the tool has been cut for a long time, the abrasive grains are naturally blunt, and the height of the blade is lowered. As the bonding agent around the abrasive grains is further worn, the holding force of the diamond is weakened, resulting in the diamond falling off.

Grinding wheel dressing is one of the key technologies in grinding. Today's grinding technology is developing towards high precision, high speed and high efficiency. This requires the grinding wheel to be trimmed with high precision and high efficiency. Diamond dressing roller is specially developed to adapt to this development. It is a new generation of grinding wheel forming and trimming tool. It has the characteristics of high dressing precision, complicated trimming surface and high dressing efficiency. It is the most effective high-efficiency and high-precision forming tool. .

The cause of the imbalance of the grinding wheel is that the center of gravity of the grinding wheel does not coincide with the axis of rotation. The reason for this is the grinding wheel manufacturing and installation defects, for example, the density of the grinding wheel is not uniform, the end faces are not parallel, the geometric shape or the concentricity error of the inner and outer holes, the grinding wheel is installed eccentrically. When the unbalanced grinding wheel rotates at a high speed, it generates a centrifugal force that forces the grinding wheel to deviate from the axis, thereby causing the grinding wheel to vibrate.
