Abstract
A method of and device for removing burrs from metal work-pieces processed by a metal processing machine is provided. The method and device both include the burrs being removed by a high pressure stream of liquid that exits a high pressure nozzle and is directed at the work-piece that is to have the burrs removed. An integration of the burr removal step into the manufacturing sequence of the parts on commercial metal processing machines is made possible by the fact that the high pressure stream of liquid that is used has a proportion of oil of greater than 50% and a high pressure of greater than 400 bar.
Claims13
A device for removing burrs from a metal work-piece processed on a shavings removal metal processing machine, the metal processing machine having at least one processing station in a machine chamber thereof, wherein the device includes a high pressure nozzle supplied with a high pressure stream of liquid to be directed at the work-piece to be processed, the device comprising:
- means for taking oil for a portion of the high pressure stream of liquid, wherein the oil is taken from an oil tank of the metal processing machine, the oil is brought to a high pressure of greater than 400 bar by a high pressure generating device, and the oil is supplied to the high pressure nozzle housed in an encapsulated work-piece chamber located in the machine chamber;
- wherein:
- the work-piece is held in a work-piece holder after shavings have been removed therefrom and the work-piece is inserted into the encapsulated work-piece chamber which is provided as the last processing station of the metal processing machine having a plurality of processing stations in the machine chamber;
- the work-piece chamber is provided with a drain exit which can be connected to an oil drain device of the metal processing machine;
- the oil from the oil tank of the metal processing machine is supplied, any one of directly or indirectly, via an oil container of the high pressure generating device;
- and
- the work-piece chamber is provided with a connection for a line that comes from gas supply.
A method of removing burrs from a metal work-piece processed on a shavings removal metal processing machine, wherein the burrs are removed via a high pressure stream of liquid exiting from a high pressure nozzle directed at the work-piece to be processed, the method comprising the steps of:
- providing a high pressure stream of liquid, wherein the liquid has a proportion of oil greater than 50% and a high pressure greater than 400 bar;
- housing the high pressure nozzle and the work-piece to be processed in an encapsulated work-piece chamber during processing of the work-piece to be processed;
- and
- supplying carbon dioxide or nitrogen via a gas supply to the work-piece chamber after the housing of the high pressure nozzle and the work-piece in the encapsulated work-piece chamber and during processing of the work-piece to be processed.
A method of removing burrs from a metal work-piece processed on a shavings removal metal processing machine, wherein the burrs are removed via a high pressure stream of liquid exiting from a high pressure nozzle directed at the work-piece to be processed, the method comprising the steps of:
- providing a high pressure stream of liquid, wherein the liquid has a proportion of oil greater than 50%, a high pressure greater than 400 bar, and is formed partially from oil used in the shavings removal metal processing machines, and
- housing the high pressure nozzle and the work-piece to be processed in an encapsulated work-piece chamber during processing of the work-piece to be processed.
A device for removing burrs from a metal work-piece processed on a shavings removal metal processing machine, the metal processing machine having at least one processing station in a machine chamber thereof, wherein the device includes a high pressure nozzle supplied with a high pressure stream of liquid to be directed at the work-piece to be processed, the device comprising:
- means for taking oil for a portion of the high pressure stream of liquid, wherein the oil is taken from an oil tank of the metal processing machine, the oil is brought to a high pressure of greater than 400 bar by a high pressure generating device, and the oil is supplied to the high pressure nozzle housed in an encapsulated work-piece chamber located in the machine chamber
- wherein the work-piece chamber is provided with a connection for a line that comes from a gas supply.
