Lead blasting causes and processing steps
Mar 13, 2018

In fact, sandblasting is more common in today's life, and this approach is not directed at the pillars. There are also a lot of die-casting products, aluminum parts, etc., all need to be grit blasted. Through the sandblasting process, all dirt such as scale on the surface of the guide pillar can be removed, thereby improving its surface finish, making it look more beautiful and more precise.

 

It can be seen that the sandblasting process is also a very important processing link in the production of pillar products. Normally, dry sandblasting machines are used in this process. Dry sandblasting machines are divided into two types, one is a suction type dry sandblasting machine, and the other is a press-in type dry sandblasting machine. In comparison, the former type of equipment is mainly powered by compressed air. The abrasive is sucked into the spray gun through a sand delivery pipe and ejected through a nozzle to be sprayed on the surface to be processed.

 

In fact, the working principle of the two is basically the same, and the latter method is more conducive to controlling the dust pollution in the sandblasting process and improving the working environment of the guide pillar sandblasting operation. So, in the processing process, the production of guide shaft products can be completed in a few steps?

 

Of course, there may be some differences in the required processes in different productions. Simple analysis, can be attributed mainly to: under the material - roughing - conditioning - heat treatment - fine grinding. The first step is to select the inner and outer circular surfaces for positioning and ensure the concentricity. At this point, it is necessary to prepare the ready-made smooth pillar blanks for finishing in the centerless grinding.

 

Next, the threaded holes of the guide posts are processed in turn, followed by heat treatment and nitriding, and finishing, that is, centerless grinding and finishing. Then, the processed outer guide bushes, springs, glands, and ball-aluminum bushings are fitted. Finally, it is also required to test whether the outer guide sleeve and the steel ball sleeve slide to determine whether the tolerance is suitable. http://www.xhychromerod.com
