如何准确翻译这个词语? 领导给我看了一下一段外文“天书”,问我是什么意思,其中有个词 aggregate 总觉得说不准确切的意思,大家帮忙讨论一下: An aggregate is used on a CNC mahining center as a tool-holder. The spindle of the CNC machining center switches among the aggregates that have been set up with different tools for different duties. For instance: here is some information and an image of an aggregate: CNC Aggregate for boring, routing, and sawing with two tool interfaces, angel 90° Speed max. 8,000 R.P.M. (drive) Speed max. 12,000 R.P.M. (tool spindle) Turn direction: left/right Gear ratio i 1:1,5 Torque max. 15 Nm Tool interfaces: Collet ER 25, saw blade flange 30 mm , diameter 150mm The question is: how to translate "aggregate" with an easy and understandable chinese word?
