设计简介
如今科学技术发展很快，特别是微电子技术和计算机技术的发展更快，应用到数控系统上，它既能提高机床的自动化程度，又能提高加工精度，所以最经济的办法就是进行普通机床的数控改造。
本文主要是采用微机数控技术对最大加工直径为400mm的普通卧式车床进行改造设计。首先对卧式车床的改造任务和功能需求进行了认真分析，其次确定了普通卧式车床数控改造的总体方案，包括主传动系统的改造方案、换装自动回转刀架、螺纹编码器的安装方案、进给系统的改造与设计方案。最后经过计算切削力、滚珠丝杠设计计算、齿轮及转矩有关计算对丝杠、齿轮等进行了选型，详细设计出了横向进给系统。

Abstract
Today, rapid development of science and technology, especially micro-electronics technology and computer technology have expanded rapidly, and applied to the numerical control system, it can increase the degree of automation, machine tools, can improve the machining accuracy, so the most economical way is to carry out general transformation of the NC machine tool.
In this paper, using computer numerical control machining technology to the maximum diameter of 400mm for the general transformation of the design of horizontal lathe. First of all, the transformation of the horizontal lathe tasks and functions carried out a careful analysis of needs, and secondly to determine the general horizontal lathe CNC overall transformation program, including the main drive system of the transformation program, installed automatic rotary tool, the installation of encoder thread program, the transformation of feed system and design. Finally, after calculating the cutting force, ball screw design, the gear and the calculation of torque on the screw, gear selection, etc., the detailed design of a horizontal feed system.
