Hairline processing is actually printing extremely fine stripes on
stainless steel plates. The surface condition of raw materials has a great influence on the quality of hairline processing, so when polishing coils, base treatment and polishing should be done before hairline processing
No.4 processing is to rotate the polishing belt of the stainless steel plate abrasive under the action of pressure, the stainless steel plate passes under it, and the surface of the plate is called the polished surface. Unlike the hairline finish, this finish is characterized by short polishing streaks.
There are two main types of mirror surface processing for stainless steel plates. One is to use the toe material as the raw material for mirror surface processing only through the grinding process; the other is to use the grinding wheel to first remove the small defects and unevenness on the surface of the raw material, and then use the grinding process Perform mirror finishing. These mirror finishes are different from BA polishing.
Vibration processing is a processing technology that attracts more attention. It is a polishing method in which the polishing head of non-woven fabric containing sand grains is given a random motion of alternating rotation and movement. By changing the number of the non-woven fabric, the pressing force of the polishing head and the movement form of the polishing head, different polishing methods can be obtained. processing.
In the polishing wheel grinding process, the raw materials used are basically 2D stainless steel plates. This is a method in which a cylindrical buff is formed by overlapping hemp and cotton cloth, rotated at high speed, and polished while supplying abrasives to the surface of the buff. While this plus is not as high quality as a mirror finish, it is glossy.
In terms of base materials, the annealed BA stainless steel sheet is different from 2B or 2D stainless steel sheets because cold rolling has a good surface, but the surface of No.1 stainless steel sheet is rough like orange peel, and it takes a long time to directly grind it. not conducive to production. The existence of such defects is caused by cracks, pits and iron scales formed during hot rolling. Therefore, when grinding No. 1 stainless steel plates and thick plates, in order to remove surface defects of the material, base grinding is generally performed. This technology has a great impact on the quality and cost of the final grinding stainless steel plate product
