目前,外圆成型磨削,采用得较多的大致有两种方法:对曲率较大成型母线较长的工件磨削加工,一般采用导轮靠模仿形机构,用金刚石修整砂轮成型后进行磨削加工;对曲率较小、形状复杂、成型母线较短的工件,一般采用预先加工出与工件形状相同的挤压轮,然后,用挤压轮去挤压砂轮成型。考虑到我们加工的旋轮数量少、型号多,如采用挤压轮挤压的方法,不 At present, the external shape grinding, used more generally there are two ways: For the larger curvature of the busbar longer workpiece grinding, the guide wheel by the general use of copy-shaped mechanism, grinding wheel with diamond dressing after grinding Cutting; For small curvature, complex shape, forming a short busbar workpiece, the general use of pre-processed with the workpiece shape of the same extrusion wheel, and then squeeze the wheel to squeeze wheel molding. Taking into account the small number of our processing rotary wheel, more models, such as the use of extrusion wheel extrusion method, not
