Sand blasting of precision parts

Dalian sand blasting and shot blasting processing shot blasting is to use the motor to drive the impeller body to rotate, and the diameter is between 0 and by the action of centrifugal force 0 balls (including cast shot, cut shot, stainless steel shot, etc.) are thrown to the surface of the workpiece to make the surface of the workpiece reach a certain roughness, make the workpiece elegant, or change the welding tensile stress of the workpiece to compressive stress, so as to improve the service life of the workpiece. It is used in most fields of machinery, such as ship repair, auto parts, aircraft parts, gun and tank surface, bridge, steel structure, glass, steel plate, pipeline, etc. Sand blasting (shot blasting) uses compressed air as energy to sand with a diameter of 0 ~ 0 mesh or 0 About 0 shot is sprayed on the surface of the workpiece to achieve the same effect. The treatment effect is different with the size of pellets It is emphasized that shot peening can also play a strengthening role. At first, the equipment at home went into a misunderstanding, thinking that only shot blasting can achieve the purpose of strengthening. Enterprises in the United States and Japan use shot peening for strengthening! Each has its own advantage. For example, for a workpiece like a gear, the shot angle of shot blasting cannot be changed, and the initial speed can only be changed by frequency conversion. However, it has large processing capacity and fast speed, while shot blasting is just the opposite. The effect of shot blasting is not as good as that of shot blasting.
