Turning machine and method for turning workpieces

A method for producing a first partially machined workpiece and a second partially machined workpiece by turning a first semi-finished product and turning a second semi-finished product in a turning machine, the method including steps comprising:

• providing a turning machine comprising:
• a first spindle, which can be set in rotation for gripping and rotating a first semi-finished product to be turned;
• a second spindle, which is opposite the first spindle and can be set in rotation, for gripping and rotating a second semi-finished product to be turned;
• wherein the first spindle is associated with a first bar load magazine, which is configured to convey the first semi-finished product through a first opening of the first spindle into a machining area located between the spindles;
• wherein the second spindle is associated with a second bar load magazine, which is configured to convey the second semi-finished product through a second opening of the second spindle into the machining area;
• producing a first partially machined workpiece by:
• conveying the first semi-finished product through the first opening of the first spindle of the turning machine into the machining area situated between the spindles;
• gripping the first semi-finished product in the first spindle;
• setting the first semi-finished product in rotation by means of the first spindle;
• turning a starting region of the first semi-finished product by means of a first machining tool of the turning machine within the machining area;
• producing the second partially machined workpiece by:
• conveying the second semi-finished product through the second opening of the second spindle of the turning machine into the machining area;
• gripping the second semi-finished product in the second spindle;
• setting the second semi-finished product in rotation by means of the second spindle and turning a starting region of the second semi-finished product by means of a second machining tool of the turning machine within the machining area;
• wherein the first partially machined workpiece and the second partially machined workpiece are produced simultaneously.

A method for producing a workpiece by turning a semi-finished product in a turning machine, the method including steps comprising:

• providing the turning machine comprising:
• a first spindle, which can be set in rotation for gripping and rotating a first semi-finished product to be turned;
• a second spindle, which is opposite the first spindle and can be set in rotation, for gripping and rotating a second semi-finished product to be turned;
• wherein the first spindle is associated with a first bar load magazine, which is configured to convey the first semi-finished product through a first opening of the first spindle into a machining area located between the spindles;
• wherein the second spindle is associated with a second bar load magazine, which is configured to convey the second semi-finished product through a second opening of the second spindle into the machining area;
• producing a partially machined workpiece by machining a starting region of a first end face of the semi-finished product by:
• conveying the semi-finished product through the first opening of the first spindle of the turning machine into the machining area situated between the spindles;
• gripping the semi-finished product in the first spindle;
• setting the semi-finished product in rotation by means of the first spindle;
• turning the starting region of the semi-finished product by means of a first machining tool of the turning machine within the machining area;
• producing a finished workpiece from the partially machined workpiece by gripping the turned starting region of the semi-finished product by means of the second spindle, separating the partially machined workpiece from the semi-finished product, machining an end region of the partially machined workpiece remote from the starting region by:
• gripping the partially machined workpiece in the second spindle;
• setting the partially machined workpiece in rotation by means of the second spindle;
• turning the end region of the partially machined workpiece by means of a second machining tool of the turning machine within the machining area, whereby the partially machined workpiece is formed into the finished workpiece;
• ejecting the finished workpiece from the second spindle.
