Abstract
The present invention provides a machining center that efficiently machines a long workpiece using two pallets. A machining center 1 includes a saddle 30 that moves in a Y axis direction on a bed 10, and a table unit 50 moves in an X axis direction on the saddle 30. At a right end and a left end of the front surface of the bed 10, setup stations 110 and 120 are respectively disposed. While a spindle head 80 is machining a workpiece W2 with one pallet 140 placed on the table unit 50, a workpiece W1 can be set up onto the other pallet 130. A long workpiece can also be machined on the two pallets 130 and 140 placed on the table unit 50.
Claims6
A machining center comprising:
- a bed;
- a column disposed upright at a rear center portion of the bed;
- a table unit mounted on the bed and configured to move along an X axis and a Y axis orthogonal to the X axis on a horizontal surface;
- a spindle mounted at a front surface of the column and configured to move along a vertical Z axis so as to machine a first workpiece or a second workpiece longer than the first workpiece;
- a first pallet and a second pallet;
- a first clamp unit configured to clamp the first pallet onto the table unit;
- a second clamp unit configured to clamp the second pallet next to the first pallet on the table unit;
- a first setup station disposed at a left end of a front surface of the bed, the first setup station being where the first workpiece is to be set up onto the first pallet;
- a second setup station disposed at a right end of the front surface of the bed with a space defined between the first setup station and the second setup station, the second setup station being where the first workpiece is to be set up onto the second pallet;
- and
- a movable device configured to move the first pallet and the second pallet between the table unit and the first and second setup stations;
- wherein when the machining center machines the second workpiece, the machining center is configured to clamp the first pallet and the second pallet onto the table unit and set up the second workpiece onto the first pallet and the second pallet from the space, and
- wherein when the machining center machines the first workpiece, the machining center is configured to clamp onto the table unit one pallet among the first pallet and the second pallet on which the first workpiece is set up.
