Problems solved by technology

[0003] The purpose of the present invention is to provide a stainless steel surface grinding and polishing process, which has the advantages of high efficiency, and solves the problem that the existing traditional processing technology is used, and the surface of the product is easily scratched and scratched during use, thereby affecting the aesthetics of the product. Some polishing and sanding processes require manual operation alone, which has high cost and low efficiency, and it is difficult to improve productivity, and it is difficult to realize automation, which cannot solve the problem of labor shortage in the current environment

Embodiment 1

[0026] First, use 100# steel grit to uniformly sandblast the semi-finished product on the surface of the product, so that each position of the product will completely appear sand grains, and then use a neutral abrasive for the semi-finished product that has been sandblasted, at a rate of 0.5 per cylinder The proportion of kilograms, the combination of brown corundum using a high-frequency shock machine to open the rough skin for 7 hours, then remove it, clean it, and dry it naturally. Wash with clean water for 3-8 minutes, rinse with pure water for 2-5 minutes, and then dry through a dryer to complete the passivation of the stainless steel surface.

Embodiment 2

[0028] In embodiment one, add following operation:

[0029] In step 1, the sandblasting is carried out by an automatic sandblasting machine, the sandblasting temperature is maintained at 30-40°C, and the sandblasting is stirred at a speed of 300-500 rpm.

[0030] First, use 100# steel grit to uniformly sandblast the semi-finished product on the surface of the product, so that each position of the product will completely appear sand grains, and then use a neutral abrasive for the semi-finished product that has been sandblasted, at a rate of 0.5 per cylinder The proportion of kilograms, the combination of brown corundum using a high-frequency shock machine to open the rough skin for 7 hours, then remove it, clean it, and dry it naturally. Wash with clean water for 3-8 minutes, rinse with pure water for 2-5 minutes, and then dry through a dryer to complete the passivation of the stainless steel surface.

Embodiment 3

[0032] In embodiment two, add following operation:

[0033] In step 2, wash with absolute ethanol first, and then with deionized water.

[0034] First, use 100# steel grit to uniformly sandblast the semi-finished product on the surface of the product, so that each position of the product will completely appear sand grains, and then use a neutral abrasive for the semi-finished product that has been sandblasted, at a rate of 0.5 per cylinder The proportion of kilograms, the combination of brown corundum using a high-frequency shock machine to open the rough skin for 7 hours, then remove it, clean it, and dry it naturally. Wash with clean water for 3-8 minutes, rinse with pure water for 2-5 minutes, and then dry through a dryer to complete the passivation of the stainless steel surface.

Abstract

The invention discloses a stainless steel surface grinding and polishing process which comprises the following steps: firstly, performing uniform sand blasting treatment on the surface of a semi-finished product by using 100 # steel grit, so that sand lines completely appear at each position of the product. The passivation process is a complete chemical reaction, a complete, compact and difficult-to-damage passivation film can be generated on the surface of the stainless steel, the size of a workpiece is not changed, the corrosion resistance of the passivated stainless steel workpiece can be improved to more than 10 times, the passivated stainless steel workpiece can pass a standard salt spray test for 500 hours at most, the surface of the treated product is wear-resistant, scratches cannot be left on the surface due to slight collision, the attractiveness of the product is improved, the product is smooth and round in edge, smooth in hand feeling and free of handedness, the use safety performance of the product is improved, the problems which cannot be solved by conventional polishing and sanding products are solved, unique retro patterns on the surface of the product are few lines in the market, the surface patterns have strong concave-convex hand feeling and can also play an anti-skid role.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing technology, in particular to a stainless steel surface grinding and polishing technology. Background technique [0002] The surface quality of stainless steel equipment directly determines the product quality. How to improve its surface quality has always been a difficult problem in this field. The surface treatment processes of existing products include polishing and sanding. However, with traditional treatment processes, the product surface is easy to Bumps and bruises will affect the aesthetics of the product, and the existing polishing and sanding processes require manual operation alone, which has high cost and low efficiency, and it is difficult to improve productivity, and it is difficult to realize automation, which cannot solve the problem of labor in the current large environment. shortage problem.
