一、概述机械零件的表面质量主要包括表面粗糙度,表面加工硬化和残余应力。这些因素直接影响零件的疲劳强度、耐磨性、耐腐蚀性以及电磁特性等。表面质量与加工方法有密切关系,各种加工方法和加工条件下所获得的工件表面质量有明显差别。一般对淬火钢加工的传统方法是磨削。但磨削淬火钢时,由于磨削温 First, an overview Mechanical parts of the surface quality, including surface roughness, surface hardening and residual stress. These factors directly affect the fatigue strength of parts, wear resistance, corrosion resistance and electromagnetic properties. Surface quality and processing methods are closely related to a variety of processing methods and processing conditions obtained under the surface of the workpiece quality are significantly different. The traditional method of machining hardened steel is grinding. But grinding hardened steel, due to grinding temperature
