Cylinder pipe is actually (honing tube, pipe mill quilting, Air mill tubes, tube honing, grinding tube, cylinder tube, cylinder tube) is actually not the same as the name of each region is called cylinder honing machine commonly used steel, machine tool spindle and the honing head general is a floating connection; However, in order to improve the ability to correct geometry of the workpiece can also be a rigid coupling. HM tube is mainly used for processing diameter of 5 to 500 mm or greater variety of cylindrical bore, such as cylinder, the valve hole, connecting rod hole and the casing hole and so on, the hole depth to diameter ratio of up to 10. Cylinder tube with rolling process, since the surface layer of the surface residual compressive stress left, helps the closed surface microcracks, hinder the expansion of erosion. Thereby improving the corrosion resistance of the surface, and can delay fatigue cracks or expanded, thus increasing the quilting grinding tube fatigue strength. Cylinder pipe surface defect repair method before processing steel tanks have a lot of surface pitting, which is affecting the quality of quilting grinding tube important factor, in order to go through to get a good quality quilting after grinding hydraulic cylinder tube, you need these hemp point for repair. So, hydraulic cylinder tube surface defect repair method, what does? 1 to increase the amount of deformation increases drawing drawing deformation passes, increase the total deformation, can be to reduce pitting depth, the purpose of reducing the honing grinding allowance. 2, preferably cold drawn pipe blanks hot-rolled tubes pitting defects are caused by the hot-rolled tube, so that, by selecting the extent of corrosion is small, uniform thickness of hot-rolled pipes, pitting can reduce defects and improve the finished cylinder rate. 3 hot-rolled tube bore defects cleanup. Quality is the premise that only good quality, and customer service is fundamental, therefore, on the surface of the hydraulic cylinder tube defects perfect restoration, is the greatest commitment to our customers. Precise chemical composition of steel cylinders of carbon C, Si Si, manganese Mn, S, P P, chromium Cr popularization and application of precision seamless steel on savings, improve processing efficiency, reduce the manufacturing processes or equipment investment is important, you can save costs and processing time, improve production capacity and material utilization, and help to improve product quality, reduce costs, improve economic efficiency is important. What is the cylinder tube | honing pipe, honing tube technology is what? Honing role is to improve the surface finish of the workpiece and the abrasion resistance, the most important point is that wear because honed surface with a certain angle of intersection textured, which can be retained in a textured oil for lubrication role in reducing frictions, so they need honing workpieces usually in a variety of automotive engine block or cylinder of various hydraulic valve hydraulic cylinder rod motorcycle cylinder cars so similar linear movement or rotation of the need to reduce the grind Sassafras extend the life of the subject. cylinder tube | honing tube characteristics: honing process (Honing Process) is a special form of grinding, finishing and is an efficient machining method. This process not only to remove a large allowance, and is a part to improve the dimensional accuracy, geometry and surface roughness precision processing method effective in the manufacture of automotive components is widely used.
