A微型数控钻铣床装配图
摘要
随着工业的发展，数控机床已经成为现代机械制造业的最主要的装备，这是一种趋势。我国数控机床在经历了30多年的发展，各项相关技术都取得了重大突破，机床种类越来越多，目前可提供1500种，覆盖超重型机床、高精度机床、沿高技术机床等领域，产品种类可与日、德、意、美等国并驾齐驱。但国产机床相对来说与发达国家之间的差距依然很大，体型大、笨重、精度不高等问题仍然是国产机床克服不了的。因此，微型化、高速化、高精度化、功能复合化等成为数控机床的一种发展趋势，本文介绍了一种可用于微型加工的微型数控钻铣床。
本文通过查阅大量国内外文献资料，经过比较和分析，设计了一台用于钻铣加工的微型数控钻铣床。本文介绍了机床总体布局、伺服控制系统、主传动系统、其他组件的选型以及设计计算，并分析了机床的功能及其应用范围。
本文介绍了一种微型数控钻铣床的设计方案，可适用于教学模型、培训上使用，让学生和初学者对数控钻铣床有一定的认识。

Abstract
With industrial development,CNC machine tools has become the mainstream of modern machineryand equipment manufacturing.Development of domestic CNC machine tools has experienced 30years of ups and downs,has matured from growth,to provide 1500 kinds of CNC machine tools,covering the super-heavymachine tools,high-precision machine tools,machine tools and other areas along the high-tech product rangewith the date,Germany,Italyand the United States to keep pace.But the gap between the domestic machine toolwith relativelydeveloped countries is still great,large size,heavy,accuracyis still not high domestic machine tool can not overcome.Therefore,miniaturization,high-speed,high precision,functional complexand so become a development trend of CNC machine tools.
Byconsulting a large number of domestic and foreign literature,through comparison and analysis,the use of SolidWorks software for micro CNC milling machine drilling three-dimensional modeling,designed a dedicated micro-drilling and milling CNC milling machine drilling systems.This article describes the overall layout of the machine,the servo control system,the main transmission system,aswell as other components of the selection of the design calculations and analysis of the function and application of the machine.
This article describes a CNC milling machine drilling miniature design,suitable for teaching model,the use of training,so that students and beginners to CNC milling machine has a certain understanding.
Keywords: High Precision; miniaturization；High speed；micro-drilling and milling machine
