20120076598 | MILLING MACHINE FOR PRODUCING TOOTHED WHEELS - A milling machine for producing toothed wheels has a workpiece receiver for receiving a workpiece to be toothed, which workpiece receiver can be pivoted relative to a machine frame about a workpiece pivot axis. To produce the tooth system, two machining units with two tool spindles are provided to receive milling tools. A first tool spindle can be moved linearly relative to the workpiece receiver in at least two directions and can be pivoted about a spindle pivot axis, which runs parallel to the workpiece pivot axis. A second tool spindle can be moved linearly relative to the workpiece receiver in at least two directions. The milling machine has high manufacturing productivity and flexibility and, in particular, also allows the production of tooth systems with an uneven number of teeth. | 03-29-2012 |
20120186053 | TOOL TURRET FOR PROCESSING WORKPIECES AND PROCESSING SYSTEM WITH THIS TYPE OF TOOL TURRET - A tool turret for machining workpieces has a housing and with a part that can be rotated around an axis of rotation into several rotary positions. On the rotating part, several tool holders are mounted on the circumference for holding tools to which a cryogenic cooling medium can be fed by means of a first feed line and a respective second feed line. The first feed line can be moved in a linear manner in at least some sections by linear actuator whereby the first feed line is connected in a first position with the second feed line belonging to the tool in work position and in a second position is disconnected from the second feed lines for changing the rotary position of the rotating part. The tool turret enables the cryogenic cooling medium to be fed to the tools in a simple and reliable manner. | 07-26-2012 |
20120186320 | METHOD AND MACHINE TOOL FOR THE PROCESSING AND HARDENING OF METALLIC WORKPIECES - A method and a machine tool are disclosed for processing and hardening metallic workpieces. The workpieces are clamped in workpiece holders and are first processed with metal cutting by means of a processing device and are then hardened by means of a hardening device. For hardening, the processed workpiece is first heated by means of a heating unit and then quenched by means of a quenching unit. The quenching occurs by means of a cryogenic cooling medium, e.g., liquid or gaseous nitrogen. Because the processing and hardening of the workpiece occurs in a clamping device, and the fast quenching of the heated workpiece, a high processing quality and short processing and/or cycle times are achieved. | 07-26-2012 |
20120198671 | MACHINING DEVICE FOR MACHINING CRANKSHAFTS AND A MACHINING SYSTEM HAVING SUCH A MACHINING DEVICE - A machining device for machining crankshafts has a rotationally driven disk-shaped base body with blade inserts arranged peripherally thereon. A first supply line for a cryogenic cooling medium is arranged concentrically with the axis of rotation and is thermally insulated in at least some sections. The tool has a plurality of second supply lines for the cryogenic cooling medium running across the axis of rotation and leading to the blade inserts, the second supply lines each being thermally insulated in at least some sections. A distributor unit connects the first supply line to at least one of the second supply lines for supplying the cryogenic cooling medium to at least one of the blade inserts. The cryogenic cooling medium can be conducted directly to the blade inserts which are engaged with the crankshaft that is to be machined. | 08-09-2012 |
