液压件阀芯是液压产品零件中的关键零件,它的尺寸精度和几何精度直接影响液压件的性能和寿命。目前,国内外液压件阀芯的精加工都在向提高加工精度和光洁度,以及提高生产效率的方向发展。从去年以来,我们进行了阀芯超精加工工艺研究,使阶梯轴类阀芯精加工圆度和同心度能稳定达到0.001毫米,光洁度达△10。大家都知道,影响阶梯阀芯加工几何精度的重要因素是中心孔的几何精度和光洁度。所以,提高中心孔的几何精度和光洁度,便为提高阀芯加工精
Hydraulic parts spool is a hydraulic parts of the key components, its dimensional accuracy and geometry of a direct impact on hydraulic performance and life expectancy. At present, the hydraulic components at home and abroad are finishing to improve the machining accuracy and finish, and improve the production efficiency direction. Since last year, we have carried out the valve core superfinishing process research, so that the ladder shaft spool machining roundness and concentricity can be stable to reach 0.001 mm, the finish of △ 10. As we all know, an important factor that affects the geometric accuracy of the ladder spool machining is the geometric accuracy and finish of the center hole. Therefore, to improve the center hole geometric accuracy and finish, then to improve the valve core processing precision
