Abstract: A guide device for bars to be fed to a machine tool includes first holding and guide arrangement and second holding and guide arrangement, arranged to define an advancement zone for the bars that extends according to a longitudinal axis. The first holding and guide arrangement and the second holding and guide arrangement are configured to establish one or more contact zones with the bar, so as to hold in position and guide the bar along the advancement zone. The first holding and guide arrangement and the second holding and guide arrangement extend parallel to the axis and are positioned on sides mutually opposite the longitudinal axis. The first holding and guide arrangement and the second holding and guide arrangement are relatively movable between a rest position, in which the first and the second holding and guide arrangement are at a greater mutual distance and at furthest positions from the advancement zone to allow the positioning of said bar to be guided along the advancement zone, and an engagement position, in which the first and the second holding and guide arrangement are at a lesser mutual distance and nearer the advancement zone so as to come into contact with the bar, adapting to different diameter values of the bar.

Abstract: A machine tool comprises a machine frame, a first spindle having a first workholder rotatable about a first axis, a second spindle having a second workholder rotatable about a second axis, a first tool carrier for machining one side of a workpiece in the first spindle, and a second tool carrier for machining a different side of a workpiece in the second spindle. The second spindle is arranged on a spindle carrier movable relative to the machine frame, using a carriage system, in parallel with and transversely to the first axis. The second workpiece spindle is pivotal on the spindle carrier, using a pivoting device, about a pivot axis that extends perpendicularly to a movement plane. The second tool carrier is positioned on a guide carriage movable relative to the machine frame in parallel with the pivot axis. A drag frame conveyor is provided to feed or transport workpieces.

Abstract: Disclosed are a wheel lightweight machining fixture and method. The fixture comprises a rotating chuck, an electric cylinder, a guide rail, a slide block, a first linear motor, radial positioning blocks and the like. When the electric cylinder drives the slide block to move along the guide rail, the position where an first ultrasonic thickness measuring sensor is in contact with a wheel spoke can be adjusted, so that the spoke thicknesses at different positions can be detected. Through motion of the turrets, an second ultrasonic thickness measuring sensor can contact the outer rim of the wheel and detect the rim wall thickness. By integrating a measurement feedback system into the manufacturing process, the disclosure provides a fixture and a method for minimum entity machining of the rim wall thickness and the spoke thickness of a wheel during the first stage turning process, thereby realizing lightweight manufacturing of the wheel.

Abstract: A lathe including a moving headstock designed to rotate and move forward a workpiece to be turned in relation to an axis of translation and rotation. A guide bush is designed to be attached to a frame of the lathe and includes a bush spindle and a clamping mechanism. The guide bush is designed to operate either in bush mode or in grip mode and is designed to be moveable axially in relation to the frame along the axis of translation and rotation. The lathe is arranged to operate in a first mode in which the guide bush is driven axially by the moving headstock, and a second mode in which the axial position of the guide bush is static in relation to the frame.

Abstract: A bar material supplying device includes a feed rod having a leading end provided with a finger chuck, a feed rod servomotor and an air cylinder device that move the feed rod in a longitudinal direction to insert and pull the bar material into and from the finger chuck, and an NC device that controls driving of the feed rod servomotor and driving of the air cylinder device. The NC device controls the driving of the feed rod servomotor and the driving of the air cylinder device to move the feed rod in an operation of inserting and pulling the bar material into and from the finger chuck, and operates as an error allowable device that allows an error of an operation amount of the feed rod servomotor motor in the operation of inserting and pulling the bar material into and from the finger chuck.
