High machining accuracy: especially for small and medium-sized through holes, the cylindricity can be up to 0.001mm. Some parts with uneven wall thickness, such as connecting rods, have a roundness of

The cold drawn tube is made on the basis of cold drawing. Because the temperature of the cold drawn tube is relatively high, the effect in long-term use and continuous development is relatively large,

Repair process of hydraulic chrome plated bar:

After the hydraulic chrome plated bar is pulled, if it is not treated in time, it will affect the normal use, but the hydraulic cylinder will not work. Our repair method is to repair the lighter stret

Rolling processing is a kind of chipless processing, which utilizes plastic deformation of metal at normal temperature to flatten the microscopic unevenness of the surface of the workpiece to achieve

In the process of application, cold drawn tubes play an important role in saving steel, improving processing efficiency and saving energy. Products are widely used in automotive, petrochemical, marine

The honing pipe is mainly used in engineering, metallurgy, plastics, mining, road construction, textile and other industries. There are three main types of honing pipes, cold rolling, cold drawing and

High-quality rolling tubes can be effectively divided into hot-rolled tubes, cold-rolled tubes, cold-drawn tubes, extruded tubes, etc., depending on the production method. Hot rolled seamless pipes ar

The honing pipe is mainly used in engineering, metallurgy, plastics, mining, road construction, textile and other industries in the process of use. There are three main types of honing pipes, cold rol

The rolled tube will have a sand bar when it is working, and a lot of abrasive grains will be placed on the sanding bar. If the abrasive grains are given enough pressure, the rolled tube will be at a

The honing pipe is a kind of high-precision pipe in the process of operation, and it is widely used in various industries. In order to ensure the normal performance of the performance, the accuracy sh

There is also the fact that the abrasive grains form a certain trajectory on the surface when the sand bars are running and moving up and down. The cutting speed of the honing pipe is relatively low,
