图1是我厂在钻井泵缸套生产中,最初设计的缸套珩磨夹具,采用端面压紧,既可预防形变,又可抵消珩磨轴向力。珩磨液通过导向套上的斜孔向珩磨孔壁四周喷射,不仅防止了珩磨液的飞溅流失,而且保证了均匀的冷却润滑。但经过一段时间使用后发现该 Figure 1 is the factory in the production of drilling pump liner, the first design of the cylinder liner honing fixture, the use of face compression, both to prevent deformation, but also to offset honing axial force. The honing fluid is sprayed to the periphery of the honing hole wall through the inclined hole in the guide sleeve, which not only prevents the splash loss of the honing fluid but also ensures the uniform cooling and lubrication. But after a period of use found that
