Impact effect of manual sand blasting machine on sand blasting abrasive processing

Dalian sanding and derusting can improve the mechanical properties of parts. After sandblasting, mechanical parts can produce uniform and fine concave convex surfaces on the surface of parts, so that the lubricating oil can be stored, so as to improve the lubrication conditions, reduce noise and improve the service life of machinery. For some special-purpose workpieces, sandblasting can realize different reflection or matte at will. Such as the polishing of stainless steel workpieces and plastics, the polishing of jade, the matte surface of wooden furniture, the pattern pattern on the surface of frosted glass, and the texturing of cloth surface.

Burr cleaning and surface beautification of machined parts sand blasting can clean the micro burr on the workpiece surface, make the workpiece surface more flat, eliminate the harm of burr and improve the grade of workpiece. And sandblasting can make a small fillet at the junction of the workpiece surface, making the workpiece more beautiful and precise.

It can not only completely remove the oxide scale, rust, old paint film, oil stain and other impurities on the metal surface and make the metal surface show a uniform metal color, but also make the metal surface obtain a certain roughness to obtain a surface with uniform roughness And change the machining stress into compressive stress Improve the adhesion between the anti-corrosion coating and the base metal and the corrosion resistance of the metal itself. Commonly used in coating, thermal spraying and plastic roughening treatment In addition to sand blasting, surface roughening treatment methods include threading method, knurling method, electric spark roughening method, etc.

Whether it is high-carbon and high-strength steel, or elastic parts, brass parts, stainless steel parts and aluminum parts enter the next process after sandblasting, the adhesion of coating or oxide layer can be improved Hard chromium plated and coated workpieces are usually cleaned by sand blasting. Machine tool accessories and tools are usually polished by sand blasting before being milky white. The impact effect of sand blasting abrasive processing by manual sand blasting machine is diverse. The effect varies from the nature and degree of abrasive used, the angle, speed, density, distance and time of sand blasting and projection, and it is easy to adjust the processing degree. The diversity of processing degree is the remarkable feature of sand blasting processing.

In the steel structure, the application of high-strength bolts for connection is a relatively advanced method. Because the high-strength connection uses the friction between the joint surfaces to transfer the force, the quality requirements of the joint surface are very high. At this time, the joint surface must be treated by sand blasting. Sand blasting is used for complex shape, easy to remove rust by hand, low efficiency, poor site environment and uneven rust removal. General sandblasting machines have sandblasting guns of various specifications. As long as it is not a particularly small box, you can put the gun in and clean it.
