The effect of 8k mirror surface is processed by machine grinding; this kind of equipment is called 8k machine or mirror steel machine or mirror polishing machine; to achieve the effect of 8k, it is ground by multiple sets of grinding discs;
Usually 8k machine is a group of 8 grinding discs; a set of 8k machine production line needs 10-15 groups for grinding and polishing; the plate or tape enters the 8k main machine in the way of pinching, and the grinding disc in the main machine rotates and grinds between groups at the same time The area of the polished plate is evenly covered by staggering left and right; after the grinding and polishing is completed, the plate is put into the washing and drying machine for cleaning and drying. Those who need to be pasted with a film can also go through a film sticking machine process.
The 8k machine needs to be polished by adding a potion prepared by nitric acid and iron oxide (or aluminum oxide), which will cause certain pollution to the environment and water flow.
Is there any grade for 8k mirror?
8k is just a general term, because each customer has different requirements for mirror surfaces; it is also divided into several grades 6K, 10K, 12K, etc. The difference between mirror grades is the level of precision and smoothness.
6K is the board surface after grinding and polishing, which is worse than a mirror, it will be a bit hazy, but it can be seen clearly;
8K, to reach the level of 8k, it needs rough grinding + fine grinding to polish the surface of the board, which is compared like a mirror;
10k and 12K refer to ultra-fine ground and polished boards, which are comparable to mirrors and have higher optical effects.
What is 8k board:
Stainless steel 8k plate (mirror panel) is the effect of mechanical grinding and polishing of BA, 2B or matte stainless steel surface through 8k mirror grinding and polishing; usually we call it 8k mirror NO8.
