Abstract
A multi-axis turning center has a spindle head, a spindle rotatably supported by the spindle head, and a table or a headstock for gripping and rotating a workpiece thereon. The table or the headstock is disposed in confronting relation to the spindle. The spindle head is relatively movable in the three mutually transverse axes directions to the workpiece gripped and rotated by the table or the headstock. A multi-point turning tool is mounted on the spindle and having a plurality of tips, for turning the workpiece gripped and supported by the table or the headstock. The spindle head is movable to translate the multi-point turning tool to one of positions around the workpiece, and the tips are selectively used depending on the one of the positions to turn the workpiece.
Claims20
A multi-axis turning center comprising:
- a spindle head;
- a spindle supported by said spindle head;
- a table or a headstock to grip and rotate a workpiece thereon, said table or said headstock being disposed in confronting relation to said spindle,
- said spindle head being relatively translatable in the three mutually transverse directions relative to said workpiece gripped and rotated by said table or said headstock;
- and
- a multi-point turning tool, mounted on said spindle and having a plurality of tips, to turn said workpiece gripped and supported by said table or said headstock;
- wherein said spindle head is movable to translate said multi-point turning tool to one of plural positions around said workpiece, said tips are selectively used depending on said one of the positions to turn said workpiece, and said spindle head is not rotated between the plural positions or when turning said workpiece with said tips.
A multi-axis turning center comprising:
- a spindle head;
- a spindle rotatably supported by said spindle head;
- a table or a headstock for gripping and rotating a workpiece thereon, said table or said headstock being disposed in confronting relation to said spindle, said spindle head being relatively movable in the three mutually transverse axes directions to said workpiece gripped and rotated by said table or said headstock;
- and
- a multi-point turning tool, mounted on said spindle and having a plurality of tips, for turning said workpiece gripped and supported by said table or said headstock;
- wherein said spindle head is movable to translate said multi-point turning tool to one of positions around said workpiece, and said tips are selectively used depending on said one of the positions to turn said workpiece;
- wherein said multi-point turning tool comprises said tool holder and a plurality of bodies removably fixed to said tool holder, said tips being mounted on respective distal ends of said bodies.
A method of turning a workpiece with a multi-axis turning center having a spindle head, a spindle supported by said spindle head, a table or a headstock to grip and rotate a workpiece thereon, said table or said headstock being disposed in confronting relation to said spindle, said spindle head being relatively translatable in the three mutually transverse directions relative to said workpiece gripped and rotated by said table or said headstock, and a multi-point turning tool, mounted on said spindle and having a plurality of tips, to turn said workpiece gripped and supported by said table or said headstock, said method comprising the steps of:
- moving said spindle head to translate said multi-point turning tool to one of plural positions around said workpiece, without said spindle head being rotated between the plural positions or when turning said workpiece with said tips, and
- turning said workpiece while said tips are selectively used depending on said one of the positions.
