1970年左右日本进行缸套内表面波纹加工研究。1973年又研究缸套振动加工工艺。继日本之后,西德与法国先后在七十年代发表了缸套表面振动切削专利和有关试验报告,共同认为振动加工的缸套贮油性能和抗拉性能都较好。 1 振动切削工艺理论依据早期的柴油机缸套技术要求是内壁呈镜面,但实际运行发现镜面上的油膜并不稳定,而往往中断,在缸套内壁的微观部分经常发生金属因直接接触而拉缸。此后,出现的是对缸套内壁珩磨网纹的研究,其目的旨在形成油膜层,但珩磨产生的变形层(即冷作硬化层)反而
Japan around the cylinder liner ripple processing studies in 1970 or so. In 1973, we studied the vibration processing of cylinder liner. After Japan, West Germany and France successively published patent and related test reports on cylinder surface vibration cutting in the seventies, and jointly agreed that the vibration performance of cylinder liner is good both in oil storage and tensile properties. A vibration cutting technology theory based on the early diesel cylinder liner technology is the inner wall of the mirror, but the actual operation found on the mirror film is not stable, but often interrupted, often in the micro-part of the liner wall due to direct contact with the metal cylinder . Since then, there has been a study of honing the inner wall of the cylinder liner, the purpose of which is to form an oil film layer, but the deforming layer (ie, cold work hardening layer) produced by honing instead
