金刚石平整法是指依靠弹簧2的作用,使金刚石工具3以一定的压力压紧于被加工零件的表面上。当搪床主轴1旋转时,金刚石工具沿着零件的表面滑动,同时在金刚石工具尖端的接触区域产生应力。由此,零件表面发生微观的形变,而起到强化零件表层的作用(见图1)。在278型搪床上,采用OH037—103—67型金刚石工具(刃磨半径为2.5～3毫米)对“格斯”—51和“吉尔”—120汽车发动机比缸内工作表面进行平整加工。平整加工装置直接安装在搪床主轴1的刀头上。借助于调整螺钉6改变弹簧2的弹力来
Diamond smoothing method is to rely on the role of the spring 2, so that the diamond tool 3 to a certain pressure on the surface of the workpiece to be machined. As the bedrock spindle 1 rotates, the diamond tool slides along the surface of the part while creating stress in the contact area of the diamond tool tip. As a result, micro-deformation occurs on the surface of the part to reinforce the surface of the part (see Figure 1). On the 278 boring machine, the working surfaces of the “Ges” -51 and “Jill” -120 car engines are machined to be machined more than the working surfaces in the cylinder, using OH037-103-67 diamond tools (grinding radius of 2.5 to 3 mm). The leveling device is installed directly on the head of a boring machine spindle 1. By means of the adjusting screw 6, the spring force of the spring 2 is changed
