How does the sand blasting machine work?

A sandblasting machine is a machine that processes the surface properties of objects. The machine mainly uses compressed air as the main power to form a high-speed jet beam to process the surface of the object, thereby changing the mechanical properties of the surface of the object. The sandblasting machine is suitable for cleaning the rough surface of forging, stamping and machined parts, for spraying, pretreatment before electroplating, and strengthening the surface of polished parts.

How does a sandblasting machine work?

Sandblasting machines come in two categories, wet sandblasting machine and dry sandblasting machine. The dry sand blasting machine uses compressed air to form a negative ejection effect in the high-speed process in the spray gun, and sucks the abrasive in the cyclone separator into the spray gun through the hose. Then, along with the compressed air flow, the nozzle is sprayed to the surface of the workpiece at a high speed to achieve the purpose of sandblasting.

The liquid sandblasting machine uses the grinding liquid slurry to provide power for the grinding liquid, and sends the evenly stirred grinding liquid to the spray gun through the grinding liquid slurry pump. The compressed air is used as the acceleration power of the grinding fluid, and is ejected through the nozzle and sprayed onto the surface of the object to achieve the desired processing purpose.

Advantages of sandblasting machines

Because the sandblasting machine uses compressed air to impact and cut the surface of the object. At the moment of high-speed spraying onto the surface of the object, the surface of the workpiece obtains a certain degree of cleanliness and different roughness. During the blasting process, the blasted metal parts are basically not damaged, and the dimensional accuracy will not change. And the abrasive does not chemically react with the part. Sandblasting with sandblasting equipment is beneficial to increase the adhesion between it and the coating and prolong the durability of the coating film. Sandblasting equipment can easily handle hard-to-reach parts such as grooves, and a variety of abrasives can be selected. Therefore, the sandblasting machine is especially suitable for the production of small and medium-sized parts and small batches.
