I'm not sure I understand your question, but I assume that you are looking for companies which provide grinding and polishing services (?). If that is correct then please specify what kind of requirements you have. Do you just need something ground to a specific thickness or straightness, or do you require lapping for a very fine finish or micropolishing for an even finer finish? Do you want to contact a company in China, the US or elsewhere? The more information you provide in your question the better answer you are likely to receive.
Hi Mark: At first,thank you for your reply, i would like to know in polishing industry, the company did well? my english is not very good, pls forgive me. thanks!
I wish I could answer your question, but I'm afraid I still don't understand your need. I would recommend that you post in Chinese (or whatever is your primary language) to see whether any others here can read it and translate. Naturally nobody expects anyone else to be proficient in a language foreign to them, so there is no need for tolerance ... just a need for clarity.
I think the original poster is looking for a good/well-known polishing/grinding company. If that's the case, I would have three questions: (1) What materials are you working with? (2) What surface finish do you require? Is this optical-grade components, or just knocking the high points off a casting? (3) Do you have any location preference?
good to know there's someone interesting in grinding wheel industry where company involves. but we're making grinding stones and wheels in China, we don't provide any grinding or polishing service since in China every firm is specializing in doing their job. Plus as Mark asked, if don't know roughness requirement or objective material, etc. we don't know what and how to give you service even if we're a grinding work shop.
