经济型数控铣床主传动及进给传动系统设计 I
摘要
科学技术的不断发展,对机械产品的质量和生产率提出了越来越高要求。机械
加工工艺过程的自动化是实现上述要求的最主要的措施之一。它不仅提高产品的质
量、提高生产效率、降低生产成本、还能够大大改善工人的劳动条件。大批量的自
动化生产广泛采用自动机床、组合机床和专用机床以及专用自动生产线,实行多刀、
多工位同时加工,以达到高效率和高自动化。但这些都属于刚性自动化,在面对小
批量生产时并不是适用,因为小批量生产需要经常变化产品的种类,这就要求生产
线具有柔性。而从某种程度上说,数控机床的出现正是很大的满足了这一要求。数
控铣床一般由控制介质、数控装置、伺服系统、机床本体四部分组成。数控装置的
作用是把控制介质、数控装置、伺服系统、机床本体四部分组成。也就是通过计算
机控制铣削。数控技术是现代制造技术的基础。它综合了计算机技术、自动控制技
术、自动检测技术和精密机械等高新技术,因此广泛应用于机械制造业。数控机床
替代普通机床,从而使得制造业发生了根本性的变化,并带来了巨大的经济效益。
可以预见,高级自动化技术将进一步证明数控机床的价值,并且正在更为广阔的开
拓着数控机床的应用领域。

ABSTRACT
The continuous development of science and technology, mechanical products, and
productivity of the quality of the increasing number of requests. The automation of the
process to achieve the above requirements. It not only improves product quality, increase
productivity, reduce production costs, but also can greatly improve the working conditions of
workers. Largescale automated production, the widespread use of automatic machines,
machine tool and special machine tools and automatic production lines, while the
implementation of multitool, multibit processing in order to achieve high efficiency and
degree of automation. These are rigid automation in the face of small batch production, it is
not suitable for small batch production, is often necessary to change the type of product,
which requires a flexible production line. But to a certain extent, C machine tool is a
great meet this requirement. The general control of the media, and numerical control device,
the servo system of the CNC milling machine, the body composed of four parts. The
numerical control device to control the media, the role C equipment, servo system, four
components of the Machine Tool. It putercontrolled milling machine. CNC technology
is the basis of modern manufac
