双轮珩磨,是通过两个反方向安装的磨轮进行磨削(图1)。珩磨轮在一定弹簧压力作用下与工件紧密接触,被工件带动旋转,并作纵向往复进给,由此产生细微磨削作用。它与单轮珩磨比较,具有能够消除单轮珩磨叶形成的螺旋形磨纹、高的光洁度、高效率等优点;在磨削细长轴时,可以克服由于单轮径向压力使工件产生弯曲的弊病。 Two-wheel honing is done by grinding wheels mounted in opposite directions (Figure 1). Honing wheel under certain spring pressure in close contact with the workpiece, the workpiece driven rotation, and longitudinal reciprocating feed, resulting in fine grinding effect. Compared with single wheel honing, it has the advantages of eliminating helical grinding, high finish and high efficiency of single wheel honing. When the slender shaft is grinded, the work piece can be bent due to the radial pressure of the single wheel The ills.
