The so-called rolling process of Seamless Carbon Hydraulic Honed Tube is a kind of chipless processing. At room temperature, the plastic deformation of metal is used to smooth the surface roughness,

The principle of the honing pipe pressing process is to use the cold plastic properties of metal at room temperature and apply a certain pressure on the workpiece with a rolling tool to make the metal

1. Improve processing efficiency: the processing speed is nearly 20 times that of honing 2. Improve surface hardness: The surface hardness increases by more than 50%. 3. Processing accuracy: The pr

When the honing tube is concavely broken, the life of key components will be affected, and most of the cylinder components will also affect the normal operation of the entire system. The reasons for t

The processing of the honing pipe is rolling, and the surface of the steel pipe is under pressure. It has a good sealing effect on small surface cracks and can prevent the surface from being corroded.
