Precision honing tube spot price sales hotline: 13676382696 Features 1. honing tube outer diameter smaller. 2. Do small batches of high precision cold drawn finished raw high accuracy, good surface quality. 4 Steel Cross area more complex. 5. Pipe better performance, relatively dense metal tube used honing material 10 # 0.07 ~ 0.13 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 20 # 0.17 ~ 0.23 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 35 # 0.32 ~ 0.39 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 45 # 0.42 ~ 0.50 0.17 ~ 0.37 0.50 ~ 0.80 ≤0.035 ≤0.035 40cr 0.37 ~ 0.44 0.17 ~ 0.37 0.50 ~ 0.80 ≤0.035 ≤0.035 0.08 ~ 1.10 25Mn 0.22 ~ 0.2 0.17 ~ 0.37 0.70 ~ 1.00 ≤0.035 ≤0.035 ≤0.25 honing tube quality problems have? 1. Quality selection consideration under normal circumstances, we are honing steel surface will be a little bit of holes which is mainly due to the material in the hot rolling process caused by parts of the surface of a high temperature, it is Parts will produce pores, leaving a lot of pitting on the part surface. In response to this phenomenon, we need to choose a small degree of corrosion of the pipe, and pipe wall to try to thick, so hot tube processing them in order to effectively reduce the pores, and to improve the quality of production of steel. 2. To change the shape of the pipe is generally cold drawn tubes we use are relatively small, which leads to pores in the surface of the pipe, it is difficult to see. We can increase the thickness and diameter of the pipe, thereby reducing the porosity of the attachment point, will not appear on the surface. 3. Pipe own shortcomings processing pipe surface pitting, porosity, and defects in the pipe itself has a certain relationship, we should try to avoid the problems caused by the pipe itself, as far as possible the pipe further processing, reduce pores, pitting and other defects production, improve production efficiency and quality of the pipe. Many factories in steel processing honing and found honing steel surface problems are ignored, it will directly affect the use of honing steel and late life. Honing tube surface quality cross textured surface is conducive film lubricant storage and maintain. Have a higher surface of the support rate (hole and shaft between the actual contact area with the mating area ratio), which can withstand greater loads, wear resistance, thereby increasing the life of the product. Honing speed is low (a few tenths of grinding speed), and the bore is in surface contact with the whetstone, so a small average grinding pressure of each of the abrasive grains, so that when the honing, heat the workpiece is small, the surface is almost no thermal damage and deterioration layer, small deformation. Honing face almost no embedded sand and squeeze hard layer. Honing the cutting tube remaining amount to achieve the desired drawing accuracy, using the smallest margin honing processing is a processing method to remove all processing methods. In the honing process, the honing tool is a guide to cut the workpiece as the workpiece extra margin to achieve the desired accuracy of the workpiece. When honing, honing tools honing artifacts need to be where the greatest margin, then gradually honing to place a minimum margin to be removed. www.sdxzgg.com www.lcxzggc.com www.hmg6.com www.lcygg.com www.fsw-zy.cn www.hnlcgg.com www.hmggs.com www.hmgongju.com www.dwymg.com www.xzymg .com
