过去,对表面光洁度要求10以上的机械零件,我厂都是采用研磨的方法,这样,不仅劳动强度大、工效低、而且质量不稳定。在生产任务重的时候,就成了关键。近几年来,我们学习应用珩磨技术,制造了一台半自动内外径珩磨机,经过生产实践证明,效果良好。采用内孔珩磨工具(图1)加工导套,光洁度10,代替了铸铁棒加金刚砂车磨工艺,减轻劳动强度,提高工 In the past, on the surface finish requirements of more than 10 mechanical parts, our factory are using grinding methods, so that not only labor-intensive, low efficiency, and the quality of instability. In the production of heavy tasks, it becomes the key. In recent years, we have studied the application of honing technology to create a semi-automatic inside and outside diameter honing machine, after production practice proved effective. The use of honing tool hole (Figure 1) processing guide sleeve, finish 10, instead of cast iron rods plus diamond grinding process, reduce labor intensity, improve workers
