Abstract
A device and method for removing chips generated by a tool operating on a workpiece using air, and for lubricating the tool using a fluid lubricant are proposed. The device includes a manifold containing air and fluid lubricant chambers, at least one lubricating fluid nozzle connecting to the lubricating fluid chamber and at least two air nozzles connected to the air chamber. The nozzles are located so that the lubricating fluid stream is directed to impinge the tool from a given direction, and the air streams are directed so that neither the chips generated nor the air streams themselves significantly disrupt the lubricating liquid stream.
Claims20
A device for removing chips generated by a tool operating on a workpiece using air, and for lubricating the tool using a fluid lubricant, the tool defining a center axis, comprising:
- a manifold within which an air chamber and a lubricating fluid cahmber are defined, said manifold further defining a center plane which intersets the center axis defined by the tool;
- at least one lubricating fluid nozzle assembly connected to the lubricating fluid chamber of the manifold, and
- at least two air nozzle assemblies connected to the air chamber of the manifold, said air nozzle assemblies being located with at least one nozzle assembly on opposite sides of the center plane.
A device for removing chips generated by a tool operating on a workpiece using air, and for lubricating the tool using a fluid lubricant, the tool defining a center axis and being mounted to a machine by mounting means, the device comprising:
- a manifold within which an air chamber and a lubricating fluid chamber are defined;
- means mounting the manifold to the mounting means for mounting the tool to the machine;
- at least one lubricating fluid nozzle for directing a lubricating fluid stream against the tool;
- a connecting line for each lubricating fluid nozzle connecting its respective lubricating fluid nozzle to the lubricating fluid chamber of the manifold;
- at least two air nozzles, each directing an air stream toward the tool;
- a connecting line for each nozzle for connecting its respective air nozzles to the air chamber of the manifold.
A method of removing chips generated by a tool operating on a workpiece at an interface of the tool and workpiece, using air, and for lubricating the tool using a fluid lubricant, comprising the steps of:
- forming at least one lubricating fluid stream and directing it against the tool;
- and
- forming at least two air streams and directing them to the interface of the tool and workpiece where the chips are generated, wherein the lubricating fluid stream impinges the tool above said interface.
A device for removing chips generated by a tool operating on a workpiece using air, and for lubricating the tool using a fluid lubricant, comprising:
- a source of air;
- a source of fluid lubricant;
- at least one lubricating fluid nozzle assembly connected to the source of fluid lubricant;
- and
- at least two air nozzle assemblies connected to the source of air, said air nozzle assemblies being located with at least one nozzle assembly on opposite sides of the lubricating fluid nozzle assembly.
