Abstract
Aggregate machine-tool use seriation , the standardized general part and the few special-purpose parts compose the university special purpose machine which multiple spindle, the multi-knives, the multi-working procedures, the multi-surface or the multi-locations simult
aneously process, its productivity compared to general engine bed high several times to several dozens times, may carry on drills, the boring, the articulation, attacks machinings and so on the silk, turning, milling. The aggregate machine-tool general part and the standard letter approximately compose 70-80%, these parts are the seriation , may carry on the mass productions. Other 20-30% special-purpose part is by is processed the components the shape, the overall size, the craft and the working procedure decided.
This enhanced the productivity in the volume production, must have to reduce the process period and the non-cutting time, moreover causes the non-cutting time and the process period superposition as far as possible, causes each attire to clamp many outside work pieces simultaneously to carry on the multi-knife processing, implements the working procedure high degree of concentration, thus widely uses the aggregate machine-tool and from generatrix .
