End-processing center for rod-shaped workpieces

A processing method for simultaneously processing a first end (2) and a second end (3) of at least one rod-shaped workpiece (4) by means of a system (1), comprising

• a conveying device (5), a first processing device (8) and a second processing device (9),
• wherein the first processing device (8) and the second processing device (9) each have a clamping device (10a, 10b) and a tool unit (15a, 15b), which tool units (15a, 15b) each have at least one chamfering device (12) in a machine housing (13) and a sawing device (11),
• the processing method comprising the steps:
• positioning the at least one rod-shaped workpiece (4) in a conveying plane (6) of the conveying device (5) transversely to a conveying direction (7);
• simultaneously supplying the first end (2) of the at least one rod-shaped workpiece (4) to the first processing device (8) and the second end (3) of the at least one rod-shaped workpiece (4) to the second processing device (9) by means of the conveying device (5);
• positioning a first end region (21) and a second end region (22) of the at least one rod-shaped workpiece (4) in the respective clamping device (10a, 10b) of the first processing device (8) and the second processing device (9);
• holding the respective end regions (21, 22) of the at least one rod-shaped workpiece (4) in each case by means of a lower clamping jaw (24) and an upper clamping jaw (25) of the respective clamping device (10a, 10b);
• cutting off a first end portion (42) and a second end portion (43) of the at least one rod-shaped workpiece (4) by means of the respective sawing device (11a, 11b) of the first processing device (8) and the second processing device (9);
• machining for applying at least one chamfer (34) to the first end (2) and to the second end (3) of the at least one rod-shaped workpiece (4) in each case by means of the at least one chamfering device (12a, 12b) of the first processing device (8) and of the second processing device (9);
• wherein
• the sawing device (11) and the machine housing (13) of the at least one chamfering device (12) are moved as a motion-coupled tool unit (15),
• wherein the respective tool unit is moved relative to a respective machine frame,
• wherein the first end portion (42) and the second end portion (43) of the at least one rod-shaped workpiece (4) are cut by means of the respective sawing units (11a, 11b) in operation during movement of the respective tool unit (15a, 15b) along a first processing direction (16) aligned normal to the conveying plane (6),
• wherein the at least one chamfer is applied to the first end (2) and to the second end (3) of the at least one rod-shaped workpiece (4) by means of the respective chamfering devices (12a, 12b) in operation during movement of the respective tool unit (15a, 15b) along a second processing direction (17) aligned orthogonal to the conveying direction (7) and parallel to the conveying plane (6), and
• where in the first end region and the second end region of the at least one rod-shaped workpiece is received by the conveying device and positioned at the respective processing device by moving or positioning of the clamping device relatively to the machine frame along the first processing direction.
