Datong Hydraulic

  Quenched and tempered process usually appears in   hydraulic cylinder rod   or pneumatic  systems. It is formed by rolling. A cold hardening layer is formed on the surface of the rolling surface, which helps to reduce the elastic and plastic deformation of the contact surface of the grinding pair, improve the wear resistance of the surface of the   Datong cylinder rod , and avoid the burns caused by grinding. Next, chamfer the installation base and the rail side reference installation surface to prevent the chamfer too large or protruding; at the same time, on the base surface processing locking thread hole for installation and fixation of the device. The latter step is to check the linear guide, such as whether there is a certificate, whether there is a bruise or rust.  The reason why the  quenched and tempered piston rod  bends is analyzed and two results are obtained. On the one hand, it is possible that the accumulation of sediment at the lo...
