液压技术在被广泛采用的同时,人们对系统中有关零件的去毛刺问题越来越为之重视,尤其是阀类零件,由诸多的过液孔和主阀孔相互贯通而形成的尖棱和所产生的毛刺,由于位于零件深层体内,许多情况下是看不见、摸不着,所以很难去除。带有尖棱和毛刺的零件,工作过程中受到高压和超高压液体的冲刷而脱落,以致使阀孔、阀杆表面被擦伤,密封件被损 Hydraulic technology is widely used at the same time, people on the system deburring parts related more and more attention, especially the valve parts, by a number of liquid holes and the main valve hole through the formation of sharp edges and The resulting burr, as part of the deep body, in many cases invisible, touching, it is difficult to remove. With sharp edges and burrs parts, the work process by high pressure and ultra-high pressure liquid erosion and fall off, so that the valve hole, the stem surface was scratched, the seal is damaged
