1、摘 要 组合机床是以通用部件为基础,配以少量专用部件,对一种或若干种工件按预先确定的工序进行加工的机床。组合机床及其自动线是集机电于一体的综合自动化程度较高的制造技术和成套工艺装备。它的特征是高效、高质、经济实用,因而被广泛应用于工程机械、交通、能源、军工、轻工、家电等行业。我国传统的组合机床及组合机床自动线主要采用机、电、气、液压控制,它的加工对象主要是生产批量比较大的大中型箱体类和轴类零件(近年研制的组合机床加工连杆、板件等也占一定份额),完成钻孔、扩孔、铰孔,加工各种螺纹、镗孔、车端面和凸台,在孔内镗各种形状槽,以及铣削平面和成形面等。它是现代制造工程(尤其是箱体零件加工)的关键设备之一
