苏联某工学院研究成功一种轴类零件的磁场磨削新工艺,专门磨削大型高强度铸铁轴类零件,其特点是在零件的加工区内(不是整个零件)建立一个磁场。从图1可见其磨削情况,1为安装在顶尖上的工件,2为砂轮,3为磁极,4为电磁铁,砂轮位于磁极之间,磁极与工件的磨削面间保持2～3毫米间隙,当电源接通后便在工件的磨削区形成闭合磁环。 A Soviet Union Institute of Technology successfully researches a new type of magnetic field grinding technology of shaft parts. It specializes in grinding large high-strength cast iron shaft parts. It features a magnetic field in the machining area of ​​the part (not the whole part). Figure 1 shows the grinding situation, 1 is mounted on the top of the workpiece, 2 for the grinding wheel, 3 for the pole, 4 for the electromagnet, the grinding wheel is located between the poles, the pole and the workpiece grinding surface to maintain 2 to 3 mm Gap, when the power is turned on in the workpiece grinding zone to form a closed magnetic ring.
