What is The Grinding and Polishing of Stainless Steel Products in Metal Forming

Stainless steel products refers to the use of stainless steel as the main raw material by sheet metal processing of household goods, industrial supplies, medical supplies, etc. collectively.

1, rough grinding, this process is mainly to achieve the removal of the workpiece above the weld left behind by the weld as well as in the last step of the process of bruises, to achieve the weld rounded initial molding, horizontal and vertical surfaces basically no large scratches, no bruises, usually with 600 # of abrasive belts in the three-sided back and forth grinding of the workpiece, the roughness of the surface of the workpiece should be able to achieve after this step of the process of R0.8 mm. in the process of polishing, we must pay attention to Tilt angle of the belt sander, but also to control the pressure of the belt sander on the stainless steel workpiece, generally speaking, with the surface to be thrown into a straight line is more appropriate!

2, semi-fine grinding, mainly for the process of unsealing to repair, as well as the last step in the sanding traces produced by further fine grinding, repeated grinding marks left in the rough grinding, is the surface of the workpiece to achieve no scratches, the surface brightens and other purposes. Usually use 800# abrasive belts to grind the three sides of the workpiece according to the previous method of grinding the workpiece back and forth. The surface roughness of this process should be able to reach R0.4mm, in this process, do not produce new scratches and bruises, if this happens, the subsequent process is difficult to repair intact.

3, fine grinding, the main purpose of this process is to grind part of the workpiece and not grinding part of the welding joints, in addition to all the scratches on the surface of the workpiece and traces of bruises, so that the surface of the workpiece is further bright, usually using 1000 # of abrasive belts is mainly the previous step of the process of the emergence of small lines of the correction of the grinding, grinding method with the same as the above. After grinding through this process, the workpiece should be basically close to the mirror effect, and the surface roughness of the workpiece should be able to reach R0.1mm.

 

1, mirror surface using high-speed motor-driven wool wheel (commercially available), with a large green wax imitation of the previous polishing method for mirror polishing, the main purpose of this process is to be completed after the previous several processes after the completion of polishing the workpiece for mirror polishing, rather than further grinding. Note that in this step of the process operation, do not rub the polishing wax to the surface of the workpiece above the cover film, pay attention not to damage the cover film.

2, polish this process is the last process of mirror polishing, with a clean cotton wheel after the mirror surface of the workpiece surface friction, all the previous processes completed after the completion of the workpiece clean, polish. The goal of this process is the surface of the workpiece can not be distinguished from welding traces, as well as waxed and polished workpiece polish, brightness to mirror reflection high 8k, and the workpiece thrown part and not thrown part of the almost indistinguishable. Achieve complete mirror effect.

Also known as mirror plate, after the abrasive solution through the polishing equipment in the stainless steel plate surface polishing, so that the brightness of the stainless steel surface as clear as a mirror.

Main use: mainly used in building decoration, elevator decoration, industrial decoration, facility decoration and other stainless steel products.

Hairline has many kinds of patterns, such as hairline (HL), snowflake sand pattern (NO4), and pattern (messy pattern), cross pattern, cross pattern, etc. All the patterns need to be processed by oil throwing hairline machine according to the requirements.

Main use: mainly used in building decoration, elevator decoration, industrial decoration, facility decoration and other stainless steel products. Stainless steel champagne gold and grain plate decorative effect.

Grinding straight hair/HL: mainly used in building decoration, elevator, building doors, panels, etc.

Oil-ground messy hair: used in elevators, building interior and exterior decorative materials, electrical products, kitchen equipment and food equipment, etc.

Dry hair: used in home appliances, elevators, kitchen equipment, decorative materials, etc.
