Honing alloy tube is a kind of high-precision cold drawn or hot-rolled steel material after processing through. Because precision steel inner and outer wall oxide layer, under high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring, flattening without cracks a bit, so the main pneumatic or hydraulic components used in the production of products, such as cylinders or cylinder, which can be seamless. Chemical composition of the alloy tube honing carbon C, silicon Si, manganese Mn, S, phosphorus P, chromium Cr. Alloy cylinder honing process tube with tube using a rolling process, the surface layer of the surface residual compressive stress left, helps a closed surface microcracks, impede erosion expansion. Thereby enhancing the corrosion resistance of the surface, and can delay fatigue cracks or expanded, thus increasing the fatigue strength of honing tube. By roll forming, cold rolling the surface layer of the hardened layer, the elastic and plastic deformation to reduce the grinding surface of the auxiliary contact, thereby improving the wear resistance of honing the inner wall of the tube, while avoiding burns caused by grinding. After rolling, the reduction of the surface roughness can be improved with the nature. Alloy honing tube rolling process is a non-cutting machining, at room temperature using a metal plastic deformation, so that microscopic surface irregularities so as to flatten the surface structure changes, the purpose of mechanical properties, shape and size. Therefore, this method can simultaneously achieve finishing and strengthen both purposes, is not able to do the grinding. Rolling is a non-cutting machining, at room temperature using a metal plastic deformation, so that microscopic surface irregularities or rolling so as to achieve the purpose of changing the surface structure, mechanical properties, shape and size. Therefore, this method can simultaneously achieve finishing and strengthen both purposes, is not able to do the grinding. Alloy cylinder honing tube processing methods straightness m diameter mm Length mm / m diameter size difference in thickness precision bore roughness μ m cold drawn 40-320 ≤ 12M 0.2-0.5 H8-H10 ± 5% 0.8-1.6 cold rolled 30 -100 ≥ 12M 0.2-0.5 H8-H10 ± 5% 0.8-1.2 drawing - honing 40-500 8M 0.2-0.3 H7-H9 ± 5% 0.2-0.8 drawing - Rolling 40-400 7M 0.2-0.3 H8 -H9 ± 5% 0.2-0.4 alloy tube Regardless honing processing method for processing, in parts of the surface always leave fine uneven marks, staggered undulating valley phenomenon, rolling processing principle: it is a kinds of pressure finishing, is characterized by the use of metal in the cold plastic normal condition, the use of rolling tool to exert pressure on the surface of the workpiece surface metal plastic flow, fill the remaining low-lying valleys to the original, and to achieve surface roughness values ??decrease. Because the surface is rolled metal plastic deformation, so cold hardening and grain tapering surface tissue, forming a dense fibrous, and the formation of residual stress layer, hardness and strength increased, thereby improving the wear resistance of the workpiece surface, corrosion and with nature. Rolling is a non-cutting plastic working method. No machining technology safe, convenient and precise control precision, several major advantages: 1, to improve the surface roughness, roughness can basically reach Ra≤0.08μm. 2, the amendment roundness, ovality can ≤0.01mm. 3, to improve the surface hardness, so that by eliminating deformation, hardness HV≥4 ° 4, after processing residual stress layer, improve the fatigue strength by 30%. 5, to improve with the quality and reduce wear and extend the life of parts, but the parts but lower processing costs.
