Tool and method for machining workpieces

A tool for machining and deburring a workpiece, comprising:

• a main tool body having an operating end,
• at least one cutting edge disposed at the operating end of the tool body;
• a receptacle in the operating end of the tool body and a deburring tool receivable in the receptacle;
• a piston connected with the deburring tool for selectively moving the deburring tool from a retracted position in the tool body to an extended position out of the operating end of the tool body, whereby the same machining tool may be operated for machining a surface of a workpiece and for deburring the surface machined.

A tool for machining a workpiece comprising:

• a rotatable main tool body having operating end;
• at least one cutting edge supported on the rotatable tool body and rotatable with the body for machining the workpiece;
• a deburring device at the main body of the tool and also rotatable with the body, the deburring device being selectively movable between an inactive position in the body of the tool and an active position exposed outside the operating end of the body of the tool enabling the deburring device to debur;
• and
• an actuating device operatively connected with the deburring device for selectively causing relative movement between the cutting edge and the deburring device so that the deburring device can be selectively moved between the positions thereof, wherein the actuating device is drivable hydraulically, pneumatically or electromagnetically.

A tool for machining a workpiece comprising:

• a rotatable main tool body having operating end;
• at least one cutting edge supported on the rotatable tool body and rotatable with the body for machining the workpiece;
• a deburring device at the main body of the tool and also rotatable with the body, the deburring device is selectively movable between an inactive position in the body of the tool and an active position exposed outside the operating end of the body of the tool enabling the deburring device to debur;
• and
• a cutter tip inserted onto the operating end of the main body of the tool and the cutting edge is supported on the cutter tip.

A tool for machining a workpiece comprising:

• a rotatable main tool body having operating end;
• at least one cutting edge supported on the rotatable tool body and rotatable with the body for machining the workpiece;
• a deburring device at the main body of the tool and also rotatable with the body, the deburring device is selectively movable between an inactive position in the body of the tool and an active position exposed outside the operating end of the body of the tool enabling the deburring device to debur, the tool having a plurality of the cutting edges arrayed around the tool at intervals;
• and
• a respective one of the deburring devices associated with each of the cutting edges for deburring a surface machined by the cutting edges.
