摘要

本论文是对XK6125数控铣床总体及横向进给传动机构设计，其内容包括：进给伺服系统机械部分设计与计算、步进电动机的计算与选型、铣床改造的结构特点、安装调整中应注意的问题等。对普通铣床进行数控改造符合我国国情，即适合我国目前的经济水平、教育水平和生产水平，又是国内许多企业提高生产设备自动化水平和精密程度的主要途径，在我国有着广阔的市场。从另一个角度来说，该设计既有机床结构方面内容，又有机加工方面内容，还有数控技术方面的内容，有利于将大学所学的知识进行综合运用。虽然设计者未曾系统的学习过机床设计的课程，但通过该设计拓宽了知识面，增强了实践能力，对普通机床和数控机床都有了进一步的了解。

关键词：横向进给系统，数控化改造，机床改造，铣床

Abstract

The present paper is to XK6125 for feed system of NC transformation, its contents include: feed servo system of mechanical part design and calculation, and the calculation of the stepper motor selection, Miller structure characteristics, installation and adjustment should pay attention to the problem. On the common milling machine numerical control transformation in line with China's national conditions, that is suitable for China's current economic level, educational level and the level of production, but also many domestic enterprises to improve the level of automated production equipment and precision degree of the main way, has the broad market in our country. From another perspective, the design is a machine tool structure in terms of content, but also organic processing aspects, CNC technical content, the university knowledge to make comprehensive use of. Although the designers have not studied the machine design course, but through the design to broaden the knowledge, enhances the ability of practice, the general machine tools and CNC machine tools have a further understanding.

KeyWords: horizontal feed system, NC transformation, transformation of machine tools, milling machine
