Abstract:
A machine tool that attaches and detaches workpieces to and from a spindle in a shorter time includes: a machining mechanism part including a spindle, a tool rest, a first-axis feed mechanism moving the spindle in a a first axis extending along a center axis of the spindle, and a second-axis feed mechanism relatively moving the spindle and the tool rest in a second axis orthogonal to the first axis; a loading mechanism part including holding parts for holding a workpiece, and a third-axis feed mechanism moving the holding parts in a third axis orthogonal to the first axis to position them at the transfer position; and a numerical controller. The numerical controller operates to move the spindle toward the transfer position and to position the holding parts at the transfer position such that the operations at least partially overlap.

Claim (Index 1):
A machine tool, comprising:\n a machining mechanism part including a spindle holding a workpiece and rotating the workpiece about a center axis of the spindle, a tool rest holding a tool, a first-axis feed mechanism moving the spindle forward and backward along a first axis extending along the center axis of the spindle, and a second-axis feed mechanism relatively moving the spindle and the tool rest along a second axis orthogonal to the first axis; a loading mechanism part transferring and receiving the workpiece to and from the spindle at a transfer position to which the spindle is moved forward along the first axis, the loading mechanism part including a holding part holding the workpiece, and a third-axis feed mechanism moving the holding part in a direction of a third axis orthogonal to the first axis to position the holding part at the transfer position; and a numerical controller numerically controlling at least the first-axis feed mechanism, the second-axis feed mechanism, and the third-axis feed mechanism, the numerical controller being configured to, for transferring the workpiece between the spindle and the loading mechanism part, execute an operation of moving the spindle toward the transfer position with the first-axis feed mechanism and an operation of positioning the holding part at the transfer position with the third-axis feed mechanism in a manner such that the operations at least partially overlap.
