在机床领域里,具有螺纹链的机床约占机床总量的一半以上,然而工程界对螺纹链误差的测量分析和控制远不及滚齿机分度链那么普遍。一、螺纹链误差分离法原理用磁栅和磁尺、光栅和光栅尺等精密元件组成的基准系统对螺纹链进行误差的测量,这种测量技术早已获得应用,但不广泛,故不便推广。这里介绍比较实用的误差分离技术原理。 In the field of machine tools, machine tools with thread chains account for more than half of the total machine tool. However, the measurement, analysis and control of screw thread errors in engineering are far less common than hobbing machine indexing chains. First, the principle of the thread chain error separation method Using a reference system consisting of precision components such as a magnetic grid and a magnetic ruler, grating and grating ruler to measure the error of the thread chain, this measurement technique has long been applied, but not widespread, it is not convenient to promote. Here is a more practical error separation technology.
