Abstract
The present invention relates to a tool arrangement (5) which includes a parting tool (6) or the like which is intended to cut off or remove a machined section from the raw material (3) held firmly in a holding device (2). Located adjacent the parting tool (5, 6) on the side thereof that is proximal to the raw material (3) is a bifurcate device (7) which is intended to coact with the edge region (3b, 6b) of the raw material that lies proximal to the machined section, at least when parting of the machine section (3a) is completed, so that upon axial movement of the parting tool and/or bifurcate device a given length of raw material will be withdrawn from the holding device (2). The invention also relates to a method of moving the raw material out of the holding device.
Claims18
A tool arrangement comprising:
- a parting tool for separating a machined section from a raw material held firmly in a holding device by rotating at least one of the parting tool and the raw material while moving the parting tool in relation to the raw material towards an axially extending center line of e rotary movement and therewith cut a groove between the machined section and the raw material,
- a bifurcate device located adjacent said parting tool on the side thereof that is proximal to the raw material, the bifurcate device being movable in relation to the raw material towards the axially extending center line of the rotary movement for coacting with an edge region of the raw material such that as at least one of the parting tool and bifurcate device moves axially a given length, the raw material will be withdrawn from the holding device,
- wherein said bifurcate device includes two device parts having mutually opposing planar surfaces , said two device parts being spaced apart a predetermined distance.
A method of moving raw material held firmly in a holding device from a held position at which a parting tool is intended to cutoff a machined section to a chosen working position, said method comprising the steps of:
- causing a bifurcate device to move into coaction with a peripheral surface of the raw material during a cutting-off process with the aid of the parting tool;
- bringing the bifurcate device into coaction with the raw material upon completion of the cutting-off process;
- loosening the raw material from the holding device;
- bringing the raw material to an intended position through the medium of a common axial movement of the bifurcate device and the parting tool;
- and
- firmly clamping the raw material in the intended position.
