Cutting Fluid Application And Debris Control Patents (Class 29/DIG50)
  • Patent number: 6161994
    Abstract: A propeller with pivoting blades is provided as a cleaning tool (1) for the work area of metal cutting machines, where the angle of adjustment for the pivoting blades is such that an air jet is generated supporting the propeller blades (15) in folding open. The propeller blade (15) is arranged in a tool changer stacker instead of a common tool or on a tool spindle and serves to automatically clean the work area by a blowing process.

  • Patent number: 6071047
    Abstract: A coolant liquid feeding method comprises feeding a coolant liquid, with air bubbles caused to form continuously therein, for cutting or grinding operation to a region under machining, expediting the splashing of air bubbles in all directions when the air bubbles impinge on the region under machining and burst, and also expediting the entry of accelerated splashed liquid particles into a cutter/workpiece pressure contact plane, thereby improving the cooling and lubrication of the region under machining, whereby the air bubbles in the coolant liquid which has failed to reach the region under machining or which, though reaching there, has left there for the recovery channel are allowed to adhere to suspended foreign matters in the liquid, thereby expediting the surfacing of the foreign matters.

  • Patent number: 4867620
    Abstract: A protective device for the top surface of a slotted milling machine table preferably comprises a rubber cover sized to overlay a desired length of the table at one end thereof, the surfaces of the cover each having a raised peripheral lip and longitudinally extending beads and ribs. The downwardly directed beads fit within the slots of the milling table to hold the cover in place while the downwardly directed ribs provide air space between the placed cover and the table, thereby inhibiting rust. The upwardly directed raised lip prevents coolant spillage from the top of the cover while the coolant return holes enable excess coolant to be returned to the slots residing therebeneath. To provide protection for a reduced length table, the cover is made reversible by providing a transverse lip portion on one of the surfaces, located inboard of the coolant return holes.

  • Patent number: 4765212
    Abstract: Chip remover for machines which perform a machining operation, especially on metallic workpieces, such as strip edging machines, turning machines, etc. The chip remover has a stretched spiral rotating about its longitudinal axis with successive turns spaced apart from one another. The free upper end of the spiral extends into the chip discharge area of the machining tool. This spiral carries the chips away from the area about the tool to assure unhampered machining. The spiral is in the form of a hollow helix and is surrounded, on the outside, with only minimal clearance, by a non-rotating guide tube having an open-topped slot running lengthwise of the tube. The upper end of the helix extends freely out of the tube.

  • Patent number: 4388029
    Abstract: Conditioning apparatus for a cast metal bar is disclosed which comprises a conveyor having a plurality of blocks each of which has a surface depression defining a bar support and guide channel, an endless support to which the blocks are mounted in an endless series with the block bar support and guide channels tandemly aligned, and means for driving the endless support and series of blocks along a circuitous path that extends generally linearly through a bar conditioning station. The apparatus also comprises hold down roller means located at the bar conditioning station for holding a cast metal bar in the bar support and guide channels of blocks being driven through the bar condition station; means for trimming a cast metal bar supported and guided in the bar support and guide channels of blocks at the bar conditioning station, and means for flushing bar trimmings from the bar supported on the conveyor at the conditioning station.
