数控机床是近廿年发展起来的一种高效能自动化机床,它为解决复杂零件的精加工,实现中、小批量零件自动化生产,提高效率,降低成本提供了一条有效途径。但全功能数控机床因技术构造复杂,造价昂贵而不易普及推广。根据我车间所承担的机械加工任务,我们认为采用一种比较简单的数控机床是合适的。因此我们对一台C620普通车床作了局部改动,仍采用原传动系统,加装电磁机构、快速马达,配做一台数控箱,这样,既发挥了数控技术的优点,又满足了生产的需要。
CNC machine tool is a high-performance automatic machine tool developed in recent 20 years. It provides an effective way to solve the problem of finishing complex parts, realize the automatic production of medium and small batch parts, improve the efficiency and reduce the cost. However, full-featured CNC machine tools due to complex technology structure, expensive and not easy to promote. According to the machining tasks undertaken by my workshop, we think it is appropriate to adopt a relatively simple CNC machine tool. Therefore, we made a partial modification to an ordinary lathe C620, still using the original drive system, the installation of electromagnetic institutions, fast motor, with a digital control box, so that both play the advantages of numerical control technology, but also to meet the needs of production .
