Abstract
A dry machining apparatus includes: a tool that machine a workpiece; a first surface that is arranged below the tool and receives chips generated by the machining; a second surface that is arranged upper than the first surface; a third surface that connects the first surface and the second surface; and an air jet nozzle that has an air jet port which jets air toward a boundary portion between the second surface and the third surface from the second surface, and the air jet nozzle supplies at least a part of the air jetted from the air jet port to the first surface.
Claims14
A dry machining apparatus, comprising:
- a tool that machines a workpiece;
- a receiving surface arranged below the tool and the workpiece, said receiving surface comprising
- a first surface that is arranged below the tool and the workpiece and which receives chips generated by the machining;
- a second surface that is arranged above the first surface;
- and
- a third surface that connects the first surface and the second surface;
- said apparatus comprising an air jet nozzle that has an air jet port which jets air toward a boundary portion between the second surface and the third surface from the second surface, said air jet nozzle supplying at least a part of the air jetted from the air jet port to the first surface.
A dry machining apparatus, comprising:
- a tool that machines a workpiece;
- a first surface that is arranged below the tool and receives chips generated by the machining;
- an air jet nozzle that has an air jet port that jets air;
- and
- a tubular member that has at least a part thereof being arranged around the air jet nozzle, and has an air outflow port that supplies, to the first surface, air that has flown in from an air inflow port formed between the tubular member and an outer surface of the air jet nozzle, and air that has been jetted from the air jet port.
A dry machining apparatus, comprising:
- a tool that machines a workpiece;
- a first surface that is arranged below the tool and receives chips generated by the machining;
- and
- an air jet nozzle that:
- has:
- an air jet port that jets air;
- and
- an inner flow channel including:
- a narrowed portion;
- a reducing diameter portion having cross sectional area that decreases toward the narrowed portion;
- and
- an expanding diameter portion having cross sectional area that increases toward the air jet port from the narrowed portion;
- and
- the air jet nozzle supplies, to the first surface, at least a part of the air that has flown through the inner flow channel and has been jetted from the air jet port.
