Abstract
In transfer and unit machine design, the headstockprocessing craft is a key. "A three charts card" including processingcomponents working procedure chart, processing schematic drawing,engine bed assembly drawing, production efficiency computation card. Processing components working procedure chart is expressed a aggregatemachine-tool to is processed the craft content schematic drawing whichthe components should complete. It including processing spot sizeprecision, content and so on surface roughness and specification. The processing schematic drawing indicated is processed the componentsin the engine bed processing process, the cutting tool, auxiliaryposition condition, work piece and jig, position relations engine bedvarious spare parts and so on between cutting tool, as well as enginebed power stroke and operating cycle and so on. The engine bed assembly drawing expressed the engine bed eachcomposition part mutually coordinates the relations and variouscomponents, the part, the standard letter, General Work piece and so on thename, the code number, the quantity and the movement relations.Examines various parts between the relative position and the sizerelates whether satisfies the processing request, the general part is whether appropriate and so on the content.

(一) 组合机床(transfer and unit machine)的设计内容
组合机床是按系列化,标准化通用件及按工件的形状和加工工艺要求设计的专用件所组成的高效机床,组合机床90%为通用件,10%为专用件,故来加工产品有很大的优点.
组合机床的特点:
1.主要用于棱体其零件和杂件的孔面加工.
2.生产高,因工序集中,可多共面、多轴、多刀同时加工.
3.加工精度稳定.
4.研制周期短、便于设计、制造和使用维护,成本低.
5.自动化程度高,劳动强度低.
6.配置灵活,因结构是横块化,组合化,可按工件或工序,因大量通用部件和少量部件灵活组成或各种类型的组合机床及自动化.
