The principle of polishing stainless steel sheet

Stainless steel sheet processing technology refers to the needs of the industrial production process of stainless steel products that are mechanically processed for the shearing, bending, bending, welding and other properties of stainless steel. In the process of processing stainless steel sheets, a large number of machine tools, instruments, stainless steel sheets Processing Equipment. The stainless steel plate has a smooth surface and has many characteristics such as high plasticity, strong toughness and strength, corrosion resistance and high temperature resistance. And the processed stainless steel plate has a uniform surface, fine texture and good aesthetics.

Due to the increasing development of society, the application of stainless steel sheet processing is becoming more and more extensive, but many people do not know what the principle of stainless steel sheet processing is, why do it, and what is the polishing principle of stainless steel sheet processing? How much do you know? Today Topson will introduce the relevant information to you:

The surface of the workpiece is modified with flexible polishing tools and abrasive particles or other polishing media. Polishing does not improve the dimensional or geometric accuracy of the workpiece, but is aimed at achieving a smooth surface or specular gloss, and is sometimes used to remove gloss (matting). A polishing wheel is usually used as a polishing tool. The buffing wheel is generally made of several layers of canvas, felt or leather, and is clamped on both sides by a metal circular plate. The edges of the wheels are coated with a polish, which is an even mix of micro-abrasives and grease. When polishing, the high-speed rotating polishing wheel (circumferential speed above 20 m/s) applies pressure to the workpiece, so that the abrasive surface of the workpiece is rolled and micro-cut, so as to obtain a bright machined surface, and the surface roughness can generally reach Ra0 .63 to 0.01 microns; glossy surfaces can be matted to improve appearance when using a grease-free matting polish.

Roller polishing is often used in mass production of bearing steel balls. During rough polishing, a large number of steel balls, lime and abrasives are placed in an inclined cylinder. When the drum rotates, the steel balls and abrasives randomly roll and collide in the drum to remove the convex front and reduce the surface roughness, and the edge of about 0.01 mm can be removed. During precision casting, steel balls and fur fragments are put into wooden barrels and rotated continuously for several hours to obtain a dazzling and bright surface. The polishing of the thin wire ruler is to soak the surface to be processed in a polishing solution, and add chromium oxide powder and emulsion with a particle size of W5 ~ W0.5 to the polishing solution. The polishing wheel is made of uniformly degreased wood or special fine felt, and its movement trajectory is a uniform and dense mesh. After polishing, the surface roughness is less than Ra0.01 micron, and no surface defects can be observed under a 40x magnifying glass. In addition, there are methods such as electrolytic polishing.

Topson reminded that understanding the principle of stainless steel plate processing is helpful for our improvement, or if there is a problem to modify it, so it is necessary to understand the working principle.
