MACHINE TOOL

A machine tool (1) includes a first spindle (10), a second spindle (20), and a joining means (51) for joining the axial ends of workpieces (W1, W2) gripped by the spindles (10, 20) to form a joined workpiece (W3). The machine tool (1) further includes an electric servomotor (33) for moving the first...

Beschreibung
Zusammenfassung:	A machine tool (1) includes a first spindle (10), a second spindle (20), and a joining means (51) for joining the axial ends of workpieces (W1, W2) gripped by the spindles (10, 20) to form a joined workpiece (W3). The machine tool (1) further includes an electric servomotor (33) for moving the first spindle (10) in the direction intersecting the axis of the first spindle (10), a current value detection means (53) for detecting the current value of the electric servomotor (33), and a misalignment detecting means (52) for detecting misalignment of a first workpiece (W1) and a second workpiece (W2) in the joined workpiece (W3), based on the current value detected by the current value detection means (53) when the joined workpiece (W3) gripped by the two spindles (10, 20) is rotated.
