The workpiece processed by the customer requires a relatively smooth (low roughness) and cannot be replaced, because the grinding shot is passivated and ground, and there are still many edges and corners, which cannot be compared with the roundness of the steel shot. In addition, the hardness of the grinding shot is about 8hrc higher than that of the steel shot. The higher the hardness, the greater the roughness produced.
The workpiece is a thin-walled part, which is easy to deform, such as a thin plate (steel plate below 10mm), such as a small-diameter long steel pipe (within 2 inches) with a length of more than 6 meters. Because the hardness of the grinding pellet is high, the force generated after the impact is greater, the force is mutual, the reaction force of the workpiece is greater, and it is easy to deform. In addition, the grinding pellets are not hollow, the density is about 7.8 g/cm3, and they are not easily broken. The basic silo is full of large particles, and the density of the steel shot is about 7.4 g/cm3. When using, many of the silo are small particles, so the unit volume The weight of the grinding pellets inside is larger, and the impact force is stronger.
