Polishing thinning amount
Thread Content
Dear sea friends, I need help: The container is made of S30408 material. If mechanical polishing is used with a precision of 0.4, how much thickness reduction will there be as a result of polishing? If mechanical polishing is used with a precision of 0.1, what is the amount of thinning?
When the mechanical polishing precision is 0.4, the thinning amount is approximately 0.03 to 0.05 millimeters. If the precision is 0.1, the thinning amount may be between 0.01 and 0.02 millimeters. The specific values depend on the actual polishing process and equipment. .
Thank you. But there is a question: why is the thickness reduction for Ra0.1 smaller than that for Ra0.4? Shouldn’t it become thinner the more it’s thrown?
Ra01 indicates a higher surface finish, meaning the surface is smoother. Achieving a higher level of smoothness usually requires more delicate polishing operations, with finer polishing materials and methods being used, resulting in a relatively small amount of material being removed. In contrast, the surface finish requirement for Ra04 is not as high, so rougher polishing methods may be used to remove a greater amount of material. Therefore, although the surface of Ra01 appears smoother, it actually thins less than Ra04. .
To reduce it to 0.1, the number of polishing passes will increase, and thus the amount of thinning caused by polishing will also increase, right?
