文档介绍：CA6140车床数控化改造
内容摘要
车床数控化改造研究是提高我的重要项目。我国目前拥有大量超期服役和技术陈旧的机床急待更新。由于资金受限,相比于添置新的数控车床,对车床进行数控化改造是一条节约资金、快速上马的有效途径。车床的数控化改造具有针对性强、大大节约原材料和资金以及扩大机床应用范围等优点,主要内容包括总体设计方案的确定、对车床导轨进行改造设计和自动回转刀架的选型与安装等。
关键词: 车床改造数控化节约
Abstract
CNC lathe transformation research is to improve the level of technical equipment of our important projects. Extended active duty in our country now has a large number of obsolete machines and technology that need to be updated. Because of limited funds, compared to procure C lathe, C lathe for transformation is a savings, Express launched an effective way. CNC lathe has targeted transformation, substantial savings in raw materials and capital and to expand the scope of application advantages such as machine tools, including the main contents of the program to determine the overall design of the lathe guide the design and automatically transform the rotary tool holder of the Selection and Installation and so on.
Keywords: CNC Lathe savings
