Generally, the polishing speed of the grinding wheel is 2500m/min on the stainless steel pipe grinding machine, and the matters needing attention in the polishing. Polishing with 150-240 abrasive belt can obtain continuous lines. Precision stainless steel pipe fittings are a kind of hollow strip steel, which is widely used to transport oil, natural gas, water, gas, steam and other fluids. In addition, when the bending and changing strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structure.

It has good flexibility, corrosion resistance, high temperature resistance, abrasion resistance, tensile resistance, water resistance, and has excellent electromagnetic shielding functions. Stainless steel pipe is a hollow long round steel, widely used in petroleum, chemical, pharmaceutical, food, light industry, mechanical surface and other industries. Industrial pipelines and mechanical structural parts such as workbenches. In order to achieve the purpose of mirror polishing, we need to gradually polish with a fine abrasive, and then polish with a finer polishing paste.

The precision stainless steel pipe fittings conflict on the surface of the steel pipe. The operation is generally divided into two steps. The initial step is cutting and polishing, and the second step is colorful polishing. The fine scratches left by the previous polishing (such as the smooth gold process) are polished by the polishing wheel. The abrasive does not adhere to the grinding wheel, but the rotating grinding wheel will interfere with the cutting smoothing agent and stick some smoothing agent (function: can reduce or prevent interference and wear). Cutting smoothing agent is made of artificial abrasives (such as oxygen, aluminum (Al), hard smooth grease as a binder). They are infiltrated in the wheels of cloth. Colorful polishing and shredding are the same, except that the smoothing agent is colored (for example, red iron powder). After the surface reaches the requirements, use white lime powder (calcium carbon (C) calcium (Ca) powder) or chalk powder to "scrub" with a soft flange plate or flannel cloth. Roll polishing is a combination of abrasive and interference, which is beneficial to the surface treatment of small parts.

Polishing of precision stainless steel pipe fittings with No. 4 polishing (description: the process of friction to make the object (such as gold) smooth) thin plate (property: gemological term) when manufacturing the workpiece sheet: when (gemological term) the workpiece produced, welding Area needs secondary treatment, using the following manual methods can be basically together with the original surface; welding seams and parallel lines, can be used to weld a grinding wheel for a polishing, and then polishing and 80 special portable grinding wheel with a grain size of 120 or 150 grinding wheel The direction of the welding movement should be the same as the original wire, so that the wire is mechanically polished on the surface; if it is not parallel, the final polishing of the precision stainless steel pipe should be the same as the direction of the mechanical grinding. If the lines at the two ends of the seam are not together (for example: welding parallel to this side, perpendicular to the other side of the weld), the best way is to follow the polished weld (without crossing the weld).
