The sandblasting machine process is to use compressed air as the power to form a high-speed jet beam to spray abrasives (steel sand, brown corundum, glass beads, emery, etc.) on the surface of the workpiece to be processed at high speed. The sandblasting machine changes the appearance of the outer surface of the workpiece. Due to the impact and cutting action of the sand on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, thereby improving the workpiece Its fatigue resistance increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating. The portable sand blaster machine uses compressed air as the power to form a high-speed jet beam, which sprays abrasives on the surface of the workpiece to be processed at a high speed, so that the outer surface of the workpiece is physically changed to meet the quality requirements.
The main application range of Sandblasting equipment
1. Workpiece coating and pretreatment of work piece bonding. The portable sand blaster machine can remove all dirt such as rust on the surface of the work piece, and establish a very important basic pattern on the surface of the work piece (that is, through the so-called rough surface). By changing the abrasives of different particle sizes, such as flying-spread abrasives, the abrasives can reach different degrees of roughness, which greatly improves the bonding force between the workpiece and the coating and plating. Or make the bonding part stronger and better quality.
2. Cleaning and polishing of rough surface of castings and workpieces after heat treatment. Sandblasting can clean all dirt (such as oxide scale, oil stains, etc.) on the surface of castings and forgings and workpieces after heat treatment. Sandblasting machine polishes the surface of the workpiece to improve the workpiece The smoothness can make the workpiece show the same metal color, and make the appearance of the workpiece more beautiful and beautiful.
3. Burr cleaning of machined parts and surface beautification sandblasting can clean up the tiny burrs on the surface of the workpiece, and make the surface of the workpiece more smooth, eliminate the hazards of burrs, and improve the quality of the workpiece. And the sandblasting machine can make small round corners at the junction of the surface of the workpiece, which makes the workpiece more beautiful and more precise.
4. The sandblasting machine can improve the mechanical properties of the parts. After sandblasting, the mechanical parts can produce uniform and fine uneven surfaces on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubrication conditions, reducing noise and increasing the service life of the machine.
5. Sandblasting equipment has the function of light decoration. For some special purpose workpieces, the sandblaster can realize different reflective or matt at will. Such as the polishing of stainless steel workpieces and plastics, the polishing of jade, the matting of the surface of wooden furniture, the pattern on the surface of frosted glass, and the texturing of the surface of cloth.
