对于中小批生产,采用可换加工装备是经济生产和合理化生产的重要前提。按照“刀具移动,工件不动”的原则,可发展一种新型机床,这种机床用于多品种生产时,具有辅助时间短和便于改装的极大灵活性。特别有意义的是,机床本身完全和工件无关,只是带有和工件有关联的一些装置(如夹具、多轴主轴箱等)而已。 一、概述 在中批量生产中,需要采用可换加工装备已不是什么新问题。采用这些装备,对中小批量重复生产就必须要达到经济加工的目的,也就是说,必须减少设备的投资费用和加工工件时设备的改装时间必须尽量短。
For small and medium batches of production, the use of exchangeable processing equipment is an important prerequisite for economic production and rationalized production. In accordance with the “tool movement, the workpiece does not move” principle, the development of a new type of machine tool, the machine used for many varieties of production, with aided a short time and easy modification great flexibility. Of particular significance is that the machine itself is completely workpiece-independent, with only some devices (such as jigs, multi-spindle heads, etc.) associated with the workpiece. First, an overview In the mass production, the need to use replaceable processing equipment is not a new problem. The use of these equipment, for small and medium batches of repeated production must be to achieve the purpose of economic processing, that is, you must reduce the investment costs of equipment and processing of parts of the equipment modification time must be as short as possible.
