Jilin large diameter cylinder tube produced varieties specifications: Diameter diameter 30mm-300mm, wall thickness 2mm-40mm. Technical conditions: H5-H10 precision bore bore roughness Ra≤0.63um, straightness ≤0.3mm / m. Steel is 20 # -45 #, 16Mn, 27SiMn and some low-alloy steel standard GB8713-88. Honing production of major equipment: 350 tons of prestressed high-precision hydraulic drawing machine and 150 tons each in Taiwan, pulling machine maximum travel 12 meters, the maximum drawing force of 350 tons. And there are two sets of vertical honing machines, horizontal honing machine 2. Main purpose: hydraulic, pneumatic cylinder; hydraulic lines; spinning, textile and printing machinery pipe; automobile shock absorber tube; sleeve tube; rod and precision steel pipe. According to customer requirements are also available: Length of pipe, tube and special honing heat pipe. Jilin large diameter cylinder tube company to provide the following services: * Zero run, one from the sale. * Customers can pick and choose the desired length or other requirements. * Booking, purchasing all kinds of steel products or special specifications spot. * Swap temporary lack of specification of the library, eliminating the need for you to run around the procurement of hard work. * Arrange transportation, large straight hair you can specify the location. Now I have a lot honing tube, hydraulic cylinder tube, HM tube, cylinder tube, rod tube, bearing steel, high-precision drawing stock, will be preferential prices, wholesale and retail ways, to provide you with fast quality service, welcome new and old customers to negotiate, Power Conference high processing characteristics of large diameter pipes of large diameter cylinder cylinder tube machining accuracy especially small and medium honing tube through hole, the column of up to within 0.001mm. Some non-uniform wall thickness part, such as rods, roundness can reach 0.002mm. For macroporous (pore diameter above 200mm), roundness up to 0.005mm, if no annular groove or the like radial holes, straightness to within 0.01mm / 1m is possible. Honing than grinding high precision, because the support bearing grinding wheel is honing hole located outside, will produce bias, especially small hole machining, grinding accuracy is worse. Honing steel is generally only improve the shape precision machined parts, in order to improve the positional accuracy of parts, need to take the necessary measures. Such as improving the vertical parts of the face and the axis of the panel (panel mounting bracket on the stroke, adjust it to the large diameter cylinder tube surface quality is good for cross-textured surface is conducive film lubricant storage and kept there relatively high surface support rate (actual contact area between the hole and the shaft and with area ratio), which can withstand greater loads, wear resistance, thereby increasing the life of the product. Low honing speed (is grinding several tenth speed), and is in surface contact with the hole Whetstone, so a small average grinding pressure of each of the abrasive grains, when such honing, heat the workpiece is small, almost no surface thermal damage and deterioration layer, deformation. honing surface and almost no embedded sand squeeze hard layer. cutting large diameter cylinder tube remaining amount to achieve the required drawing accuracy, using the smallest margin honing processing is a processing method for removing all processing methods In the honing process, the honing tool is a piece of the workpiece as a guide to cut the extra margin to achieve the required accuracy of the workpiece. When honing, honing tools honing artifacts need to be where the greatest margin, then gradually honing to need removing the smallest margin place.
