一、前言近年来加工中心机床投入市场的台数急剧增加起来,并被利用到镗床、铣床、钻床等各加工领域,给机械加工自动线带来变革。用自动传送连接几台加工中心机床,即可实现全自动化。就数控装置来看,由于控制装置的小型电子计算机化,增加了各种附加的功能和可靠性。加工中心机床发展中具有下列特点: 1) 高速化——提高了主轴转数及定位速度 2) 提高精度——静精度及动精度 I. Foreword In recent years, the number of machining centers’ machine tools entering the market has dramatically increased. It has also been applied to various processing fields such as boring machines, milling machines and drilling machines to bring about changes to automatic machining lines. Automatic transfer connection with several machining centers, machine tools, can be fully automated. In terms of numerical control devices, due to the small electronic computerization of the control device, various additional functions and reliability are added. Machining center has the following features in the development of machine tools: 1) speed - increased spindle speed and positioning speed 2) to improve accuracy - static and dynamic accuracy
