多线砂轮磨削螺纹是一种高效率的加工方法,一般适用于0.75～3毫米螺距螺纹的批量生产,螺距过大的螺纹不宜采用。这种方法是在砂轮外圆面上修整出与被加工螺纹牙型相同的多个环形齿成为多线砂轮,再用它来磨削螺纹。多线砂轮的厚度可以大于工件螺纹部分的 Multi-line grinding wheel grinding thread is a highly efficient processing method, generally suitable for 0.75 ~ 3 mm pitch thread mass production, thread pitch is too large should not be used. In this method, the outer surface of the grinding wheel is trimmed with a plurality of annular teeth which are the same as those of the processed thread form to form a multi-line grinding wheel, which is then used to grind the thread. The thickness of the multi-line grinding wheel can be larger than the thread part of the workpiece
