Stainless steel polishing issues
Thread Content
There is a device that needs to be polished to a finish of 0.1–0.2 μm; it is made of 304 material, and comes in rod and sheet forms with welds in its structure. I looked up some information and checked forums as well; it seems that manual mechanical polishing can achieve this level, with rough polishing, fine polishing, and precision polishing, using green polishing paste. But after all, I’ve never done this before; I hope those who are experts in this field can explain in detail the techniques and methods involved. If the polishing task is outsourced, how is the processing fee calculated? What is the general unit price?
The price per unit for polishing is quite high; you need to be prepared for that
Choose the right abrasive particle size, increasing it step by step. Observe carefully to ensure no residue of scratches remains, and finally apply a passivator. If you have any questions, please call 13898980209
The precision of manual mechanical polishing can reach double zero; if you need to polish the tank thoroughly, feel free to contact me. I specialize in polishing; my phone number is 13674299779. Polishing process: Remove the oxide scale using pickling or artificial resin wheels; perform rough polishing with 80# and 240# grits, followed by defect detection and patch welding. If it is pure 304, this step is not necessary; by increasing the polishing grade from 400# to 800#, a precision of 0.2 can be easily achieved. The processing fee depends on your situation; it’s roughly a few hundred RMB per square meter
Thank you to all the friends above for their advice.
I have a simple question: is the polishing price calculated per ton or based on the approximate area? :lol

One manufacturer I dealt with charged by weight, which puzzled me. If measured by ton, aluminum pipes of the same specification are much more expensive than iron pipes

The cost of manual polishing should be fairly reasonable; here we generally use either manual or mechanical polishing when dealing with stainless steel manufacturers and metal components such as agricultural tools.

Could you explain the 8th floor in more detail? What exactly is the price? Is it by area or weight?
This depends on what workpiece you are polishing
