How to choose according to the workpiece roughness of steel shot
- Nov 13, 2017 -
Steel shot blasting cleaning machine mainly USES steel pill on the high speed rotating disk using the effect of centrifugal force, the high-speed steel shot hit parts surface, to achieve the purpose of cleaning parts surface, shotblast cleaning function make parts surface compressive stress, and there is no containing silicon powder, small pollution to the environment.
Steel shot function is to clean up the workpiece, the choice of steel shot and working efficiency is proportional to the correct selection of steel shot is the key to improve the work efficiency.
Correct selection of steel shot should pay attention to the following questions;Determine the steel balls mainly depends on the kinds of artifacts, you want pills for aluminum or stainless steel is generally used in non-ferrous metal.
Ordinary steel, welding, casting, such as the steel will choose steel shot;Steel shot diameter, the greater the cleaned up the surface roughness is higher, but the efficiency is very high.
Irregular shape of the steel grit and steel cut wire shot cleaning efficiency than the spherical pellet, but the surface roughness is high also.Clean up the high efficiency of the projectile to equipment wear and fast;Just use time to calculate, but production efficiency compared to the wear and tear is not fast.
The hardness of steel shot and cleanup is proportional to the speed, but and is inversely proportional to life.So the higher the hardness of steel shot, clean up the faster speed for a long time, but short life consumption is big, so hard to be moderate (about HRC40-50 advisable) to use the best effect.
Choose steel shot with moderate hardness, excellent elasticity of steel shot, every place to clean up the room, also can reduce the processing time.
