研磨丝杠是一项技术性很强的工作,除了要正确选择丝杠与研磨的材料、磨具设计、热处理规范,以及确定研磨手法等外,还需要一种简便而可靠的测量装置,以便对研磨中的丝杠随时进行检测,保证整个研磨工作顺利进行。本文介绍的是我们在研磨精密丝杠时采用的方法——多光束干涉法,整个测量装置结构简单,测量精度高,使用起来也很方便。 Grinding screw is a highly technical work, in addition to the correct choice of screw and grinding materials, abrasive design, heat treatment specifications, and to determine the grinding practices, but also requires a simple and reliable measuring device, in order to Grinding the screw at any time to ensure that the entire grinding work smoothly. This article describes the method we used to grind the precision screw - multi-beam interferometry, the entire measuring device has the advantages of simple structure, high measuring accuracy and easy to use.
