What to do if the texturing effect of the roll texturing shot blasting machine is not ideal?

Generally, the roughness may not meet expectations when using new equipment and new shot materials.

Some users may first suspect that the equipment has issues. First of all, I want to tell you

that roll texturing equipment is a mature product and would not have such major design flaws.

Secondly, shot blasting is the most mature texturing process.

The failure to achieve the desired roughness mainly lies in the hardness of the selected steel grit. According to the hardness of the roll,

choosing the appropriate steel grit hardness is the most critical factor, and it has little to do with the size of the steel shot.

Did the user purchase qualified steel grit according to our recommendations?
