Abstract
There is provided a machining center capable of simplifying a driving force transmitting mechanism and restraining occurrence of noise and vibration. A machining center having a turret head 20 with a plurality of tools on a turret base 5 includes one tool drive motor for each tool, the tool drive motor rotary driving the corresponding tool independently.
Claims7
A machining center comprising:
- a turret head with a plurality of tools;
- a tool drive motor for each tool, said tool drive motor rotary driving the corresponding tool independently;
- and
- a processing control means for controlling a first tool drive motor to rotary drive a first tool for processing a workpiece, the processing control means also controlling a second tool drive motor to rotary drive a second tool while the first tool is still processing the workpiece, and the processing control means indexing the turret head to position the second tool at a processing position once the processing by the first tool is completed,
- wherein said processing control means controls a rotation speed of the second tool to reach a rotation speed for processing a workpiece while the first tool is being rotary driven during processing a portion of the workpiece.
A machining center comprising:
- a turret head with a plurality of tools;
- a tool drive motor for each tool, said tool drive motor rotary driving the corresponding tool independently;
- and
- a first drive circuit for rotary driving a first tool drive motor;
- a second drive circuit for rotary driving a second tool drive motor;
- and
- a processing control unit for rotary driving a tool drive motor in a processing step and a tool drive motor for a next step by sequentially switching said tool drive motors driven by said first and second drive circuits,
- wherein said processing control unit controls a rotation speed of the second tool to reach a rotation speed for processing a workpiece while the first tool is being rotary driven during processing a portion of the workpiece.
A method for operating a machining center including a turret head with a plurality of tools and a tool drive motor for each tool, said tool drive motor rotary driving the corresponding tool independently, comprising the steps of:
- rotating a first tool by a first tool drive motor and processing a portion of a workpiece using the first tool;
- rotating a second tool by a second tool drive motor during said step of processing a portion of the workpiece;
- controlling a rotation speed of the second tool to reach a rotation speed for processing the workpiece during said step of processing a portion of the workpiece;
- and
- indexing the turret head to position the second tool at a processing position following completion of said step of processing a portion of the workpiece.
