How to deal with scratches (including scratches, scratches, etc.) on mirror stainless steel plate?
If the mirror stainless steel plate is scratched carelessly, appropriate methods can be used to remedy it.
As a manufacturer of stainless steel polishing plates, customers often ask similar questions.
Generally, if it is not a deep scratch, during mirror polishing, the scratch area can be smoothed as much as possible by slowing down the feed roller speed and lowering the grinding head.
There are several kinds of scratches on mirror stainless steel: first, the plate is scratched before processing; second, the plate has been finished with mirror processing, and then it was scratched.
If it is the first type of scratch, you need to judge the severity of the scratch.
If the scratch area and depth have exceeded the customer’s acceptance limit for the final product effect, then the qualified plates should be re-selected (returned or replaced or re-purchased materials).
Before plate processing, judge whether the final finished products meet customer requirements.
This can save time and financial costs.
There are many kinds of scratches, such as spot scratch, linear scratch and large area scratch.
The spot scratches, no matter their depth, can be repaired by argon arc welding, and then polished by a polishing machine.
After polishing, they can be processed twice (or more) by mirror polishing equipment, which can basically solve this problem.
If it is a linear scratch, it is what we call a scratch.
It is relatively difficult to deal with scratches.
Shallow scratches can be solved by the above methods (slow down the feed roller speed and lower the grinding head).
Deep scratches are not easy to handle.
It is recommended that you try to avoid scratch areas when processing and cutting mirror panel materials.
Large area scratches (scratches) can also be divided into two types: scratch depth, and the treatment method is the same as above
If it is the second kind of scratch, it is more difficult.
Because this kind of secondary scratch should be avoided.
It is recommended that you reduce or avoid the possibility of scratches on the mirror panel by the following methods: pasting protective film on the surface of the panel, packaging the panel with a wooden frame, padding cardboard or plastic plates on the top and bottom of the panel, packaging the entire panel with waterproof paper, and indicating the words “Protect the panel, do not scratch” on the panel or packaging surface.
The finished mirror stainless steel plate, if there are scratches, can be basically fixed according to the above method.
If the equipment that has been made into semi-finished products (with mirror surface) has scratches, a variety of polishing equipment (such as a hand-held polishing machine that can replace a variety of polishing wheels) should be used together to achieve better repair effect.
