设计简介
摘要：
本课题是围绕将普通机床改造成经济型数控机床展开设计的，经济型数控机床是指价格低廉、操作使用方便，适合我国国情的装有简易数控系统的高效自动化机床。中小型企业为了发展生产，常希望对原有旧机床进行改造，实现数控化、自动化。经济型数控机床系统就是结合现实的的生产实际，结合我国国情，在满足系统基本功能的前提下，尽可能降低价格。价格便宜、性能价格比适中是其最主要的特点，特别适合在设备中占有较大比重的普通车床改造，适合在生产第一线大面积推广。企业应用经济型数控型系统对设备进行改造后，将提高产品加工精度和批量生产的能力，同时又能保持“万能加工”和“专用高效”这两种属性，提高设备自身对产品更新换代的应变能力，增强企业的竞争能力。
利用微机改造现有的普遍车床，主要应该解决的问题是如何将机械传动的进给和手工控制的刀架转位，进给改造成由计算机控制的刀架自动转位以及自动进给加工车床，即经济型数控车床。
进行数控机床的改造是非常有必要的。数控机床可以很好地解决形状复杂、精密、小批量及多变零件的加工问题。能够稳定加工质量和提高生产效率，但是数控机床的运用也受到其他条件的限制。如：数控机床价格昂贵，一次性投资巨大等，因此，普通车床的数控改造，大有可为。它适合我国的经济水平、教育水平和生产水平，已成为我国设备技术改造主要方向之一。
现我选用C616普通车床为例进行数控改造。
关键词：C616普通机床、数控改造、纵向进给，横向进给、机床外形改造。
