常见的垫圈、摩擦片、样板、薄板等这样的薄片零件 ,它的刚性差、散热困难 ,热处理后弯曲 ,装夹时引起夹紧变形 ,磨削时易翘曲与变形 ,难于保证零件两端平面的平行度精度。然而 ,通常采用磁力吸盘在平面磨床上磨削加工 ,磨削完成后 ,去掉磁性吸引力 ,薄片工件恢复原状。如图 1 Common washers, friction plates, templates, sheets and other such thin parts, it’s poor rigidity, heat dissipation, bending after heat treatment, clamping caused by clamping deformation, easy to warp and deformation of the grinding, it is difficult to ensure the parts at both ends Flatness parallelism accuracy. However, it is common to use a magnetic chuck for grinding on a surface grinding machine. After the grinding is completed, the magnetic attractive force is removed and the sheet workpiece is restored to its original shape. Figure 1
