Abstract: A lathe system includes a spindle capable of gripping a bar and moving back and forth in an axial direction of the bar and a tool post to which a first tool is attached. The lathe system can manufacture a plurality of products having an identical shape from the bar by repeating a machining of the bar, a cutting off of a machined portion of the bar, and a grip change by the spindle, the grip change by the spindle comprising releasing the bar, moving back, and re-gripping the bar at a predetermined gripping position. The lathe system further includes a gripping position selecting unit capable of selecting a special gripping position at which the spindle re-grips the bar when a state of the machine tool system meets a predetermined condition, the special gripping position being different from the predetermined gripping position.

Abstract: Provided is a machine tool and a method for controlling the machine tool capable of precisely determine a success or a failure of a cut-off. An NC lathe performs a cut-off of a workpiece gripped by a first spindle and a second spindle and then performs a separation movement of the second spindle in a direction separating from the first spindle. The NC lathe includes a movement controlling unit adapted to perform a stop control of the first spindle at a command position of the first spindle during the separation movement of the second spindle and a cut-off success or failure determining unit adapted to monitor a positional deviation of the first spindle during the separation movement of the second spindle to determine a success or a failure of the cut-off, the positional deviation being a difference between the command position and an actual position of the first spindle.

Abstract: A lathe includes a spindle, an opposite spindle, a tool post, a controller, and a contact-type breakage detector. The controller determines whether the cut-off tool is broken according to a control parameter for controlling at least one of the spindle and the opposite spindle at a first detection timing immediately after the cut-off tool cuts off the bar material while the opposite spindle holds the bar material held by the spindle. The controller determines whether the cut-off tool is broken according to a detection result by the contact-type breakage detector at a second detection timing different from the first detection timing.

Abstract: A lathe capable of facilitating maintenance of a chucking mechanism. A chuck operating apparatus includes a claw and a shifter to open and close a chuck provided on a spindle. The tilt claw provided outside the spindle has a first posture to bring the chuck into the opened state and a second posture to bring the chuck into the closed state. The shifter provided outside the spindle and movable in a spindle axis direction is brought in a first position to bring the claw into the first posture and in a second position to bring the claw into the second posture. A roller is mounted on the shifter in a contact position with the claw to roll in the spindle axis direction.

Abstract: The invention provides a machine tool capable of facilitating a switching between a guide bush mode and a non-guide bush mode. A machine tool comprises a headstock provided with a main spindle for gripping a workpiece, a rail extended along a main spindle axis, a first bearing fixed to the headstock and guided on the rail, a second bearing fixed to the headstock on the front side of the first bearing and guided on the rail, a supporting bed on which a guide bush is removably mounted, and a guide mounted on the supporting bed to movably support the headstock in a direction of the main spindle axis when the guide bush is removed. The rail provides a larger play on the second bearing when the headstock is supported by the guide than when the headstock is not supported by the guide.
