ABSTRACT:
The chuck, the bar which operates it, and the cylinder and piston assembly which moves the bar are axially hollow and form a vertical duct which is open at the top next to the workpiece and which is open at the bottom over a conveyor with a filter and a unit for collecting and pumping the cutting fluid. The chips from the piece are channelled and removed downwards through the said duct by at least one jet of fluid at high pressure, which has a location and direction such that it strikes the chip after its formation without interfering with the normal jet of fluid at low pressure which is applied to the tool. The said jet or jets of fluid at high pressure consist of the same cutting fluid as that which is directed against the tool at low pressure. The chips leaving the lower end of the said duct fall on to the conveyor which removes them and separates them from the cutting fluid which, when suitably filtered, is returned to circulation by low-pressure and high-pressure pumps.
