平顶网纹珩磨是一项新颖的、先进的工艺技术。国外在70年代就开始研究和应用这项技术。其特点是粗珩时先磨出深沟纹,精珩时再磨出平顶,由此获得平顶网纹缸孔。表面网纹的沟槽内可均匀地贮存一定的润滑油膜,润滑性好,摩擦系数小,运动噪音小,精度稳定;表面网纹的平顶可作为工作支承面,以提高支承的能力。尤其对高温、高压、润滑极不充分条件下工作 Flat-top textured honing is a novel, advanced technology. Abroad in the 70’s began to study and apply this technology. It is characterized by coarse grooving mill deep groove, fine grinding and then flat top, which obtained flat-top reticulated cylinder hole. Surface texture groove can be evenly stored in a certain film of lubricating oil, good lubricity, small friction coefficient, low noise, precision and stability; surface texture of the flat top can be used as a working support surface to enhance the ability of support. Especially for high temperature, high pressure, lubrication under extremely inadequate conditions
