    Zhongtong tells you: How to scientifically grasp the thickness of stainless steel mirror polished wo

    In ordinary flat polishing activities, the thickness of the workpiece is usually concentrated between 0.3-20mm, and the thicker it is, the easier it is to be ground. The reason is that during the grinding process of stainless steel mirror polishing machines, if the product thickness is too thin, it is often difficult to withstand the pressure caused by grinding. The most common damage is breakage or edge collapse, and even deformation may occur if the temperature rises. However, if the thickness is sufficient, the possibility of the above-mentioned threats will be greatly reduced.
