The Influence Factors of Shot Blasting Amount of Shot Blasting Machine on Workpiece

What effect does the shot blasting amount of the shot blasting machine have on the workpiece?

There are many factors that affect the shot blasting quality of the shot blast machine, such as the size of the steel shot, the speed of the shot blasting, the amount of shot blasting, etc. What effect does the shot blasting amount of the shot blast machine have on the surface treatment of the workpiece? The shot blasting amount is a very important factor for the cleaning effect of the workpiece. The shot blasting amount can be suitable for your workpiece. You cannot blindly pursue a high shot blasting amount.

If the amount for the shot blast machine is too large, it will not only affect the efficiency of shot blasting cleaning but also affect the performance of castings, resulting in excessive surface hardness and reduced processing performance. From a professional point of view, in order to achieve better results when dealing with workpieces, the shot blasting amount should not be too large, because a large flow will increase the wear process of workpieces, and will also cause damage to fans and recovery systems. A certain pressure, it is difficult to screen thoroughly, and finally, the blasting effect of the abrasive shot blasting machine is not good, and the dust and residual abrasive after shot blasting are serious, because the pressure borne by the recovery and filtration systems will exceed their maximum load.

If the shot blasting amount is too small, the surface quality of the casting will not meet the design requirements. This also involves the shot blasting amount per unit time. Generally speaking, if the shot blasting amount per unit time is larger, then the cleaning of the casting will take a lot of time. The time will be less, but it does not mean that the larger the amount of shot blasting per unit time, the better. Because when the amount of shot blasting per unit time is too large, the projectiles entering the inner cavity of the casting may not be poured out in time. However, the steel grit will hit the steel grit, which will reduce the shot blasting efficiency.
