As we all know, grinding is the smoothing and precision machining of the surface of the part. The abrasive particles coated or pressed on the grinding tool are used to complete the processing through the relative movement of the grinding tool and the workpiece under a certain pressure. Some people think that grinding and polishing are the same, but grinding and polishing are two different processi...

The previous article introduced that grinding is the smoothing and precision machining of the surface of the parts. The abrasive particles coated or pressed on the grinding tool are used to complete the processing through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding and polishing are two different processing methods. Compared with polishing, the s...

One of the ways to restore a failed precision mechanical part is to use thermal spraying. First of all, the surface of the workpiece needs to be pretreated, and the degree of bonding between the coating and the base material (workpiece material) is the key. If the bonding cannot be performed or the bonding strength is not enough, the spray coating will be peeled off from the substrate, failing to ...
