Polishing grade
Thread Content
There is a set of equipment in use, and the material being processed is quite viscous; the material used is stainless steel. To prevent the material from sticking to the walls of the cylinder, polishing is necessary. I would like to know: 1. The methods for polishing; 2. The level of polishing required as well as the desired roughness after polishing; 3. Whether there are any relevant standards. Thank you! Urgent! ! ! ! ! !
Take a look at the book \"New Technologies, New Processes for Surface Treatment and Welding of Stainless Steel and Stainless Steel Products, along with a Quick Reference Guide to Steel Grades in Chinese and Foreign Languages\"; it contains some information on this topic. The polishing roughness should be specified by the client; if not specified, I think 0.8μm would be appropriate, as required for mechanical polishing. If higher requirements are needed, then chemical polishing, electrochemical polishing, and so on are required.
Hello, the poster. At http://bbs.cmiw.cn/forums/172123/ShowPost.aspx, there is a document titled “Comparison of surface finish grades and Ra values taken from the Mechanical Engineer’s electronic manual”. If the requirements are not high, it is possible to use “surface roughness comparison samples” for verification.
Polishing methods include mechanical polishing and electrochemical polishing, etc. The polishing grade is determined according to the design requirements.
Could you send this to me? Thank you. Email: 2361507914@qq.com
