Sand blasting machine is a machine that uses compressed air as the power to form a high-speed spray beam to spray the spray material to the surface of the workpiece to be processed at high speed, so that the mechanical properties of the outer surface of the workpiece surface are changed.
Sand blasting is a method of cleaning the surface of parts by blowing out the blasting abrasive at high speed with compressed air. The factory is also called sand blowing, which not only removes rust, but also removes a small amount of oil, which is very useful for painting. It is often used for rust removal on the surface of parts; it is used for surface modification of small parts (small wet blasting machine is used for this purpose, sand grain is usually corundum and the medium is water); in steel structures, the use of high-strength bolts for connection is a relatively advanced method Because the high-strength connection uses the friction between the bonding surfaces to transmit force, the quality of the bonding surface is very high. At this time, the bonding surface must be treated by sandblasting.
Shot blasting machine, a casting equipment that cleans or strengthens the surface of the casting by using high-speed shots thrown by a shot blaster. The shot blasting machine can perform sand dropping, core removal and cleaning on the casting at the same time.
The shot blasting machine uses the motor to drive the impeller body to rotate. By the action of centrifugal force, the balls with a diameter of 0.2 to 3.0 (including cast shot, cut shot, stainless steel shot, etc.) are thrown on the surface of the workpiece, so that the surface of the workpiece reaches a certain level. The degree of roughening makes the workpiece beautiful, or changes the welding tensile stress of the workpiece to compressive stress, which improves the service life of the workpiece. Used in almost all areas of machinery, shipbuilding, auto parts, aircraft parts, gun and tank surfaces, bridges, steel structures, glass, steel plates, pipes, etc. Sand blasting (pellet) is to use compressed air as power to spray sand with a diameter of 40 to 120 mesh or about 0.1 to 2.0 on the surface of the workpiece, so that the workpiece achieves the same effect. The treatment effect is different when the size of the pellets is different. The key point is that shot peening can also enhance the effect. Now domestic equipment has entered a misunderstanding, thinking that only shot blasting can achieve the purpose of strengthening. US and Japanese companies use shot peening for strengthening! Each has its own advantages. For workpieces such as gears, the shot blasting angle cannot be changed, and the initial speed can only be changed by frequency conversion. However, it has a large amount of processing and fast speed, and shot peening is just the opposite. The effect of shot blasting is not as good as shot peening.
