Grinding tube is a through cold drawing or after hot rolling processing of a high precision
Our factory specializes in stainless steel tube reservation non-standard alloy honing honing cylinder tube tube, first we value quality customer service second we improve third fast delivery!!
Cylinder
Rolling processing principle: it is a kind of pressure finishing, is characterized by the use of cold plastic metal at room temperature, using the rolling tool to put some pressure on the surface of the workpiece, the workpiece surface of metal plastic deformation, fill in the original residual indentation trough, and reach the surface roughness value reduction. Because of the plastic deformation of the rolled surface metal, the cold hardening and grain refinement of the surface layer, the formation of dense fiber, and the formation of residual stress layer, the hardness and strength increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a non cutting plastic processing method.
No cutting technology is safe, convenient, and can accurately control the accuracy, several advantages:
1, improve the surface roughness, roughness can reach Ra or 0.08µ m.
The 2 amendment, roundness, ovality can be less than 0.01mm.
3, improve the surface hardness, the deformation is eliminated, the hardness increased more than 4 DEG HV
4, residual stress layer after processing, improve fatigue strength increased by 30%.
5, improve the quality of cooperation, reduce wear and tear, prolong the service life of parts, but the processing cost of parts is reduced.
Several advantages of cylinder tube:
1, improve the surface roughness, roughness can reach Ra or 0.08µ m.
 
2, fixed roundness grinding tube, ovality can be less than 0.01mm.
 
3, improve the surface hardness of grinding tube price, make the stress deformation is eliminated, the hardness increased HV more than 4 degrees
 
4, after machining residual stress layer grinding pipe manufacturers, improve the fatigue strength increased by 30%.
 
5, improve the quality of cooperation, reduce wear and tear, prolong the service life of parts, but the processing cost of parts is reduced.

Thick wall pipe cutting margin less grinding
In order to achieve the precision required by the drawing, honing is the least processing method to eliminate the allowance in all the machining methods. In honing process, the honing tool uses the workpiece as the guide to remove the excess allowance of the workpiece to achieve the required precision of the workpiece. Honing, honing tools honing the workpiece to the largest margin, and then gradually honing to remove the minimum margin of place.
