Abstract
An index-feed machining system having such a construction that a plurality of machining units on which a cassette incorporating a plurality of machining tools detachably mounted are disposed at intervals of mp (m being a given positive integer, p being a workpiece-feeding pitch) in the workpiece-feeding direction corresponding to a plurality of machining processes. The machining processes being sequentially performed by the machining units at the workpiece-feeding pitches, in which driving devices for driving the machining tools are provided in the cassette comprising a plurality of machining units, and the driving force of the driving devices of a particular machining unit is made larger than the driving force of the driving device of other machining units.
Claims12
An index-feed machining system comprising:
- a base;
- a plurality of machining units movably connected to said base in a workpiece feeding direction, each of said plurality of machining units including a machining means for machining a workpiece, said each machining unit also including a driving means formed by a fluid-pressure cylinder for driving said machining means, said each machining unit includes a cassette means or holding said machining means and for detachably connecting said machining means to said each machining unit, said each machining unit including position member means for positioning said cassette means at a predetermined location on said each machining unit, said driving means of said each machining unit being connectable to a metal working tool of said cassette means when said cassette means is in said predetermined position;
- a single low pressure pump means supplying low pressure fluid to said fluid-pressure cylinder of each of said plurality of machining units;
- a single high pressure pump means supplying high pressure fluid to said fluid-pressure cylinder of each of said plurality of machining units;
- selector valve means connected to each fluid-pressure cylinder and for passing the low pressure fluid to said fluid-pressure cylinder for moving said machining means to the workpiece, said selector valve means passing the high pressure fluid to said fluid-pressure cylinder for actual machining of the workpiece.
