Brief Description of Stainless Steel Mirror Polishing
The definition of stainless steel mirror polishing is to polish a stainless steel workpiece into a mirror surface. Due to the different appearance of the product, there are many types of stainless steel mirror polishing. There are many methods for polishing the surface of stainless steel, including mechanical polishing, chemical polishing, and electrolytic polishing. But the mirror effect obtained by these methods is not high. Now Hyde shares with everyone a method called CMP mechanical chemical polishing. This method is only applicable to stainless steel workpieces that require pure flat, small size, and high-precision mirror polishing, also known as stainless steel mirror polishing.
Stainless steel mirror polishing material
Materials required for stainless steel mirror polishing materials: stainless steel polishing machines, synthetic iron discs, polishing pads, grinding fluids, fixtures or fixtures; Related consumables include adhesive wax, adhesive paper, ultrasonic cleaning agent, etc. If it is mass production, more materials are needed and the processes are also finely divided.
Introduction to stainless steel mirror polishing process and polishing principle:
The stainless steel mirror polishing process utilizes free abrasive particles to move relative to the machined surface of the workpiece and the base surface of the grinding disc, resulting in a very high flatness and smoothness of the workpiece surface. The workpiece does not require strong clamping, vacuum, or magnets to be fixed, but is naturally placed on the grinding disc, which is basically suitable for processing any metal and non-metallic material workpiece. There is no mandatory clamping or rigid grinding of general grinding machines, The reduction of secondary deformation caused by impact and heat generation is more conducive to high-precision and high finish machining. Even an inexperienced operator can easily achieve the optimal polishing effect with a parallelism of up to 0.2um and a roughness of up to Ra0.02um.
Stainless steel mirror polishing method
Common mirror stainless steel is divided into three types: 6K, 8K, and 10K. Generally, it is ordinary polishing, ordinary 6K, fine grinding 8K, and ultra strong fine grinding 10K. There is generally no significant difference in thickness, and the 10K mirror surface is brighter: the thicker the thickness, the worse the effect, and the higher the processing cost. To be more professional, concepts such as roughness and parallelism can be introduced. The specific polishing method is as follows:
The first is not: rough grinding of stainless steel, also known as "rough grinding". The purpose is to reduce the size and achieve a certain geometric accuracy. The method is to first design the fixture based on the stainless steel workpiece to play a fixed role: then install it. Then put it into a flat grinder for grinding. As there are many types of stainless steel, the grinding disc and grinding fluid can be selected according to the specific material.
A very beautiful stainless steel mirror polished workpiece. The process involves traditional rough grinding, rough polishing, precision polishing, and mirror treatment to achieve perfect results. Our company has a mature metal material polishing process, which is smooth as a mirror after polishing, without any corners, pits, or scratches. We also provide various metal mirror polishing fluids with favorable prices and excellent quality.
The stainless steel mirror polishing process is usually divided into three steps: rough grinding, rough polishing, and fine polishing. If the flatness of the workpiece itself is good, the rough grinding step can be skipped. The selection of grinding fluid is crucial, as detailed in Hyde's introduction to grinding fluids.
Stainless steel mirror polishing method - rough grinding
Stainless steel rough grinding or called The purpose is to reduce the size and achieve a certain geometric accuracy. The method is to first design the fixture based on the stainless steel workpiece, in order to play a fixed role; then install it. Then put it into a flat grinder for grinding. Since there are many types of stainless steel, the grinding plate and grinding fluid can be selected according to the specific material. Generally, the rough grinding work is carried out through a synthetic iron plate. If the flatness of the product is poor, it is necessary to grind off a certain size before grinding Only then can it reach a plane, which invisibly increases its difficulty. Therefore, when selecting synthetic iron discs, several points should be considered, which are the reasons for the high hardness and good cutting force of synthetic iron.

This process mainly involves the process of rough polishing and angle guidance through white paper. During this process, there are three points to pay attention to. The first is the weight. If the weight is too light, the marks on the iron plate cannot be thrown away. The specific weight depends on the hardness of the workpiece. The second issue is that if this product needs to guide the angle, a piece of soft leather needs to be placed under the white cloth to help guide the angle, but the soft leather should not be too soft. If it is too soft, there will be no cutting force. The third issue is the selection of liquids. Many manufacturers provide liquids with average quality, which makes it impossible to achieve the effect of throwing them in a short time. This process is also of utmost importance. If this process is polished well, the steps leading to the success of the product will also be accelerated.
Stainless Steel Mirror Polishing Method - Fine Polishing
Although the requirements for precision polishing are not too difficult, it is not easy to ignore. Firstly, this process is prone to small scratches on the product, so the quality of the polishing skin and polishing fluid must be guaranteed. Secondly, hygiene conditions must be improved to prevent contamination of the grinding fluid; So employees are required to pay attention to operational details.
Hyde independently develops a stainless steel mirror polishing machine, specifically designed for polishing stainless steel materials. With a specially designed stainless steel polishing fluid, it greatly improves production efficiency and reduces production costs.
