特殊工件的装夹会影响磨削质量与工效，图１所示便是一例，研制时试用多种方法，都很难保证质量且工效特低，不适应批量生产。在这种情况下，尝试利用废电磁工作台面制作专用工作台，取得理想的效果，具体做法是：①拆卸废电磁工作台面（M７１３０），将反面磨出，尔后将正面朝 Special workpiece clamping will affect the quality and efficiency of grinding, as shown in Figure 1 is an example, when developing a variety of trial methods, are difficult to guarantee the quality and ergonomics exceptionally low, not suitable for mass production. In this case, try to use the waste electromagnetic table to create a special table, to achieve the desired results, the specific approach is: ① disassemble the waste electromagnetic work surface (M7130), the negative mill out, then positive
