文档介绍：摘要
加工中心是典型的集高新技术于一体的机械加工设备,它的发展代表了一个。加工中心综合加工能力较强,工件一次装夹后能完成较多的加工步骤,加工中心对形状较复杂,精度要求高的单件加工或中小批量多品种更为适合。它也是判断企业技术能力和工艺水平标志的一个方面。如今,加工中心已成为现代机床发展的主流方向,广泛用于机械制造中。
加工中心及Z轴进给系统主要设计的是主传动系统、进给传动系统、支承系统;各个系统的原理和结构,以及几个部件之间的装配关系;每个零件的零件图。
设计工作:
,做好资料的收集和整理
,确定各个部件的装配关系和传动关系;
,根据收集的资料,设计各个部件的结构;
4零件设计,各个零件的结构和校核

Abstract
CNC machining center is typically mechanical processing equipments which gathered the high and new technique, its development represented a level of national design and manufacturing. The processing center has prehensive ability to process, it plete to the more step of processing after setting up the work-pieces, and suited for singer or the medium lot work-piece which plicated shape or high accuracy. It is an aspect to judge the technique ability of enterprise and the level of craft. Now, the processing center has e the direction of modern machine's development, widely used for the machinery fabrication.
Processing center and z axis feed motion system designed is motion system and feed motion principle and structures of each system, and assembly relation between a few assembly unit; the part drawing of each parts.
Work of design:
A: The prepare job of design, completing to collection and tidy up the data.
B: Draft the overall project of design, make the relation of assembly and transmissions of each assembly unit;
C: The design of machine. according to the collected data, design the structure of assembly unit:
D; design of parts, the structure and reference of each parts
E: Write the manual of design.
Key word: CNC machining center, contents, method
