Grinding method of shot blasting machine:

1. Centrifugal grinding method of shot blasting machine: when the ordinary rotary grinder rotates at a high speed, its material (mixture) will surround the grinding groove, and the workpiece and the grinding stone have no relative movement, so there is no relative movement difference, and the grinding effect will be greatly improved. weaken. In the centrifugal grinding method, several grinding grooves are installed equidistantly on the rotating shaft of the rotary head disc, and the planetary rotation movement is carried out, and centrifugal force is given, and the material will be surrounded by the centrifugal effect on the outer circle of the groove wall. The rotating outer disk rotates and grinds once, the grinding groove is reversed once, and the material moves in the direction of rotation where the space in the grinding groove is in contact with the upper part. Due to the pressure of centrifugal force and the forced flow speed of the material, the free grinding stone in the material and the workpiece flow, and the relative motion difference is generated due to the flow. Due to the existence of the relative motion difference, the grinding effect occurs. When the rotation speed is 140~180r/min, the relative motion difference proportional to the number of rotations and the centrifugal force will increase. Its grinding effect exceeds 60 times that of rotary grinders and 5 to 8 times that of vibrating grinders. The grinding capacity of centrifugal mills is very good, showing great grinding force. It is widely used in the finishing of precision machinery such as clocks, electronics and electrical parts, and is especially suitable for the grinding of small workpieces.


2. Water vortex grinding method of shot blasting machine: The water vortex grinding method is to put grinding stones, water and abrasives in a cylindrical grinding tank installed on a vertical or horizontal plane. With the rotation of the grinding tank, the grinding stones will A fine and rigid polishing layer is formed by centrifugal force. Loading the workpiece into the grinding layer will produce a high-efficiency grinding effect due to the relative movement difference with the grinding stone.
3. Rotary grinding method of shot blasting machine: Rotary grinding method is a processing method in which workpieces, grinding stones, abrasives, and water are installed in the grinding tank to give a predetermined rotary motion to generate a fluid layer on the surface of the material for polishing. This grinding method is more suitable for the grinding of small and medium parts and multi-variety and small batch workpieces.
4. Vibration grinding method of shot blasting machine: The vibration grinding method is to install the workpiece, grinding stone, abrasive, and water in the grinding tank to vibrate, and use the relative movement difference between the grinding stone and the workpiece caused by the vibration to grind. processing methods. The clean space generated by the rotary grinder is excluded, and 100% of the solvent in the grinding tank is utilized. This grinding method is 3 to 5 times more efficient than the rotary grinder, and the workpiece to be processed has no scratches, deformation and other phenomena. A widely used grinding method.
