For copper precision parts with high surface quality and shape accuracy requirements, the grinding process should be carried out in accordance with the precision machining process if the quality requirements are to be met. But can not copy the processing process of ordinary parts, not only can not solve the problem of grinding chips blocking the grinding wheel. And there will be precision parts surface hair pulling scratches, resulting in the reduction of precision machining quality, for the workpiece, hair pulling is the main reason affecting the quality of processing, to remove the surface of the workpiece hair pulling is the main process of copper precision mechanical parts processing to solve the problem. 

Copper material itself is soft, with such materials for precision mechanical parts processing, can be heat-treated to improve the hardness of the way. But its cutting performance is still poor, due to the copper class precision parts grinding chip clogging grinding wheel air holes, so generally do not use the grinding process for copper precision mechanical parts processing, can be used diamond car (boring) cutting method, relying on the tool tip trajectory to obtain precision parts shape accuracy and surface quality, by the cutting principle, for processing high precision precision parts, it is also difficult to achieve the technical requirements. 

What is hair-pulling? Performance is the workpiece surface direction consistent and uneven distribution of deeper scratches called hair pulling, workpiece surface hair pulling after the roughness increases, affecting the use of precision parts, how to solve the hair pulling problem, but also to solve the copper parts precision machining of the most important. 

In order to solve the problem of bristle, we should start with how to avoid hard particles entering the grinding area. To avoid hard particles entering the grinding area and to ensure the surface quality of the workpiece, the following aspects should be improved. 

1, the use of coarse grit grinding wheels, so that the micro-edge of the abrasive grain is more and sharper, easy to cut, in order to reduce the grinding force of the grinding wheel acting on the processing of precision mechanical parts. 

The hardness of the grinding wheel refers to the ease of shedding of abrasive grains under the action of external forces, and the use of medium hardness grinding wheels for copper parts can prevent the shedding of abrasive grains in grinding. 

3. Choose a grinding wheel with a looser organization, which has a loose organization and larger pores between the grinding grains! More coolant can be stored to prevent the grinding chips from clogging the wheel, while having good heat dissipation properties. 

4、Appropriately increase the flow of coolant so that it has a good cleaning effect on the grinding wheel to prevent the chips from blocking the grinding wheel stomata and flushing away debris. At the same time, it also enhances the cooling effect and takes away the cutting heat from the workpiece in time to ensure the dimensional stability of the workpiece. 

The above is a small part of the copper precision parts processing hair pulling solutions, I hope it can help you. If you have other aspects want to understand, you can come to consult us.
