Ready To Honed Tube
Attention should be paid to the use of honing pipe
Honing pipe dents will affect the life of key components, and most cylinder components will affect the normal use of the entire system. What is the reason for indentation? There are several possibilities:.
1. During cold drawing, the diameter of the steel pipe decreases too much, or the hammer of the steel pipe transitions too quickly.
2. The wall thickness is uneven and the local thickness is too thin.
3. The honing equipment is too old to meet the pipeline processing requirements.
When honing pipe dents, the life of key components is affected, and most cylinder components will affect the normal operation of the entire system. The causes of the dips are as follows:.
1. During cold drawing, the diameter of the steel pipe is too large and the hammer of the steel pipe passes too quickly.
2. The wall thickness is uneven and the local thickness is too thin.
3. The honing equipment is too old to meet the pipeline processing requirements.
Honed Tube processing principle
It is a kind of pressure finishing processing, is to use the cold plastic characteristics of metal at room temperature, the use of rolling tools to apply certain pressure on the workpiece surface, so that the workpiece surface metal plastic flow, fill into the original residual low concave trough, and achieve the workpiece surface roughness value reduction. Due to the plastic deformation of the rolled surface metal, the surface tissue cold hardening and grain thinning, the formation of dense fiber, and the formation of residual stress layer, hardness and strength, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.
