What Is Sand Blasting Machine?

Feb. 28, 2019

Sand Blasting Machine working principle:

The blasting machine uses compressed air as the power to form a high-speed jet beam to spray the spray (blasting glass beads, steel shot, steel grit, quartz sand, corundum, iron sand, sea sand) to the surface of the workpiece to be processed at high speed. The cutting machine laser cutting equipment cast iron platform changes the mechanical properties of the outer surface of the workpiece surface. Due to the impact of the abrasive on the surface of the workpiece and the cutting action, the surface of the workpiece is given a certain degree of cleanliness and different roughness, so that the surface of the workpiece The mechanical properties are improved, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, prolonging the durability of the coating film, and also facilitating the leveling and decoration of the coating, and the impurities and variegated surfaces of the coating. And the oxide layer is removed, and the surface of the medium is roughened, the residual stress on the surface of the substrate is increased, and the surface hardness of the substrate is increased. The follow-up will introduce the Flour Sand Blasting Machine.

The use of sand blasting machine: 1 cleaning of the surface of the workpiece; 2 pre-treatment before coating the surface of the workpiece; 3 changing the physical and mechanical properties of the workpiece to improve or reduce the surface roughness; the surface tension of the fingerprint lock fingerprint access control jet blasting machine Compressive stress; improve the lubrication state of the surface; reduce the motion noise of the coupler; increase the friction coefficient of the surface; 4 the finishing process of the workpiece surface.
