Mechanical blasting program introduction

The shot is to use high-speed rotation of the impeller to small steel shot or small iron balls thrown out high-speed hit parts of the surface, so it can be removed parts of the surface of the oxide layer. General blasting for irregular shape, several polishing head around with high efficiency and low pollution.

Repair, shipbuilding, blasting, blasting is widely used. But either shot or grit blasting, are used in the form of compressed air. Of course not shot on high speed rotation of the impeller can not be. In repair, shipbuilding industry in general, shot (shot) use in steel plate pre - treatment (before application of paint and rust); (repair, shipbuilding industry is iron ore) and more sand in forming the ship or segment, the role is the plate on the old paint and rust removing and re painting. In the repair, shipbuilding industry, the main role is to increase the blasting and blasting plate coating paint adhesion.

In fact, casting cleaning member is not only with the shot, to the large general first roller sand cleaning, is the casting of the riser after resection of put in the drum roll, composed of parts in the drum collide with each other, the sand surface most first clear off another shot or shot peening.

About 0.1 ~ 2.0 or most ~ 3.0 in shot blasting is used motor drives the impeller to rotate by the centrifugal force effect, the diameter of balls (cast pill \ cut pill \ stainless steel balls to be thrown to the workpiece surface and the workpiece surface to achieve certain manufacture in a rough degree, so that the workpiece become beautiful, or changing the workpiece welding stress compressive stress and improve workpiece service life. Almost used in mechanical field, shipbuilding and ship repairing automobile parts for aircraft components guns tank surface bridge steel structure of glass steel pipeline and so on. Blasting (pill) is to use compressed air as a driving force for the diameter in the 40-120 sand shot to the workpiece surface and the workpiece to achieve the same effect.

Different pellet size, to achieve the treatment effect is not the same. Key proposed: shot peening can also play a role in strengthening. Now domestic equipment into the a misunderstanding, think only shot in order to achieve the aim to strengthen the. \ USA Japan enterprise for enhanced is shotblasting and! Each have each advantage. Than as a tower of ivory gear such artifacts, blasting the pill angle can not be changed, can only change with frequency conversion speed. But it is processing a large amount of, speed, and shot peening is just on the contrary, blasting effect is not shot peening effect.

The difference between blasting and blasting-ZCMIM

The shot is to use high-speed rotation of the impeller to small steel shot or small iron balls thrown out high-speed hit parts of the surface, so it can be removed parts of the surface of the oxide layer. Also, steel or iron pill hypervelocity impact parts of the surface, causing parts of the surface of the crystal lattice distortion, the surface hardness increased, on the parts surface cleaning method, shot blasting is used to the casting surface cleaning or on parts of the surface hardening.

Sand is the use of the quartz sand blown out of a high speed on the parts surface cleaning method of compressed air. The factory is also called blowing sand, not only to rust, but also by removing oil, it is very useful for coating. Commonly used in parts of the surface rust; on parts of the surface modification (market to sell the small wet sand blasting machine is the use of sand is usually corundum, the medium is water); in steel structure and application of high-strength bolt connection is a more advanced method, due to the high strength connection is using a combination of friction surface between the transmission of force of, so the combination of surface quality requirements is very high, then you must use sandblasting on the binding surface for processing.

Shot blasting and blasting of workpiece to clear the whole decontamination, to preparing for the order, that is, to ensure the procedure requires the roughness of, also some for surface consistency, shot peening on the workpiece have strengthening effect, sand blasting is not obvious. General shot for small ball, sand is quartz sand. According to different requirements, mesh points.

Almost every day in the precision casting, sandblasting, shot blasting. Shenzhen precise powder metallurgy has 8 years of industry experience, for a variety of product surface processing, there is a professional degree and familiarity with, ZCMIM also to provide you with a variety of difficult solution, ZCMIM welcome you to understand!
