特殊工件的装夹是影响磨削质量与工效的一大难题。图1所示工件的装夹便是一例，研制时试用多种方法装夹磨削，都很难保证质量，且工效特低，不适应批量生产。 后来，我们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类），将 Special workpiece clamping is the grinding quality and efficiency of a major problem. Figure 1 shows the workpiece clamping is an example, the development of a variety of trial clamping method grinding, it is difficult to ensure quality, and ergonomically low, not suitable for mass production. Later, we made use of waste electromagnetic workstations to create a special table to achieve the desired results. The specific approach is: (1) disassemble the waste electromagnetic work surface (M7130 class), will
