Rolling processing principle: It is a pressure finishing process, which uses the cold plastic characteristics of the metal at room temperature, and uses a rolling tool to apply a certain pressure on t

The cylinder tube is processed by rolling . Because the surface layer leaves the surface residual compressive stress , it helps to close the micro cracks on the surface and hinder the expansion of cor

The cylinder tube is a high-precision steel tube material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure withou

The oil cylinder tube is processed by rolling. Because the surface layer has residual surface stress, it helps to close the micro cracks on the surface and hinder the expansion of corrosion. Thereby i

There is a layer of oil on the surface of the quilted cylinder tube and the cold drawn tube. Most of the cold drawn tubes are seamless tubes and secondary tubes for mechanical cold drawing. During the

It refers to the processing of steel plates or strips into various types of steel through cold drawing, cold bending, and cold drawing at room temperature. Advantages: fast forming speed, high output,

The main implementation of rolling quilted pipe is: rolling knife (also called rolling head, rolling tool, rolling knife, squeezing knife, extrusion head, etc.), rolling machine, etc. The principle is

Rolling and rolling is a method of cold pressing and proprietary technology, which belongs to chipless processing. Rolling and rolling is the use of metal to produce plastic deformation to achieve the

Improve the surface roughness, improve the quality of the fit, reduce wear and extend the service life of the parts, but the processing costs of the parts are reduced. Hot-rolled precision steel pipes

No matter what processing method is used for processing, there will always be fine uneven tool marks on the surface of the part, and the phenomenon of staggered and undulating peaks and valleys. Rolli

The quilted steel pipe is processed by rolling . Because the surface layer leaves the surface residual compressive stress , it helps to close the surface micro-cracks and hinder the expansion of corro

The quilted steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure w
