Due to the characteristics and advantages of diamond abrasives (diamond, diamond powder), diamond grinding wheels have become the ideal tool of choice for grinding hard and brittle materials such as glass, ceramics, gems, stones, and cemented carbide. With the progress of the times, the development of science, the needs of society, the development of new materials, grinding processing continues to develop in the direction of high quality, high precision, high efficiency, and automation. The role of diamond grinding wheels is becoming more and more obvious, and metal bonding agents The diamond grinding wheel has high strength to hold the abrasive grains, long life and less wear, so that the diamond grinding wheel can give full play to its characteristics of strong wear resistance and strong cutting ability in high-speed and ultra-high-speed, high-efficiency and high-precision grinding, especially in hard, brittle and difficult-to-machine materials. It shows its obvious advantages and is widely used. Diamond grinding wheels are used in almost all industrial sectors and fields, such as aerospace, mold manufacturing, semiconductor manufacturing, optical processing manufacturing, etc. Ceramic materials, optical materials, aircraft engine turbine blades, silicon wafer products, etc. are all commonly ground with diamond grinding wheels.

The classification of grinding wheels is roughly as follows: ceramic diamond grinding wheels, sintered diamond grinding wheels, electroplated diamond grinding wheels, single-layer brazed diamond grinding wheels, etc.

Problems that are likely to occur during product application and how to solve them are issues that everyone is more concerned about. The following is a classification and analysis of the problems that occur during the electroplating grinding wheel process:

1. Product chipping

① The plating time is too long: At this time, the parameters can be adjusted to reduce the plating time.

②Diamond is not wear-resistant and sharp enough: control the grade of diamond, such as TI TTI.

③The diamond particle size is too large: incoming material control is particularly important to control the stability of the diamond particle size.

2. Product burnt edges

① The cooling is not in place: adjust the cooling water for control.

② The grinding wheel is less exposed and not wear-resistant: reduce the time for plating thickness.

3. Grinding wheel line

①The diamond particles are coarse: adjust the diamond particle size.

② There are coarse diamond particles mixed on the grinding wheel: Check the plating solution promptly, replace it, and standardize the process operation.

③ There is floating sand on the surface of the diamond: Do a good job in pre-processing the diamond and strengthen the appearance inspection of the grinding wheel.

4. Grinding wheel broken tip

① Excessive diamond exposure: adjust the process and control the plating thickness time.

②The diamond is not sharp: replace the sharp diamond.

③The process is not reasonable enough, the amount of cutting is large, and the speed is not enough: optimize the process.

5. The grinding wheel loses sand

① Insufficient diamond pre-treatment: do secondary pre-treatment and follow strict operating procedures.

② Oxidation of the grinding wheel base: Make sure to prevent oxidation and isolation.

③A lot of diamond is exposed: adjust the process and control the plating thickness time.

④Diamond holding power: The coating's diamond holding power requires a reduction in current and matching of the diamond shaping process.

It can be seen from the above analysis that every problem that arises is closely related to the existing process and the quality of the abrasive. Grinding is a complex system engineering. The grinding wheel and grinding process should be correctly selected according to the material characteristics of the workpiece. When different grinding defects occur in the working conditions, correct methods should be adopted, so as to obtain workpieces with good processing quality and high dimensional accuracy, thereby improving production efficiency and reducing production costs.
