Article From: 3/15/2001 Production MachiningThe industry trend today is heading towards an increasing miniaturization--parts become smaller and more complicated and tougher materials put higher demands on machining capabilities. TRAUB Turning Machines, a division of INDEX Werke, Esslingen, Germany, has responded with the development of productive and flexible, cost-effective Swiss-style sliding headstock machines. This concept offers modular machine configurations based on individual needs for simple to highly complex parts. For the first time, turning machines based on a common design system using identical components for tool carriers, front attachment and backworking are available to the user for both standard turning and sliding headstock (Swiss) turning work. Both machine types are identical in programming, setup, operating and tooling. The TNK (Photo 1) is designed for standard screw machine parts in higher lot sizes from bar stock up to 36 mm or 1.417" diameter. The Swiss-type TNL has a bar capacity of 26 mm or 1.023" diameter and offers many new features such as up to four tools in cut, a heavy duty counterspindle and extensive backworking capability. Both models feature the design of the main and counterspindle with integrated motorspindle synchronous drive technology, providing high drive power in a compact design package. The machine achieves highest thermal stability by means of the active temperature control system. The synchronous drive technology also provides high power, excellent vibration characteristics and high C-axis stiffness. The larger TNL 26 provides these additional capabilities to machine the most demanding parts: 12 stations and additional Y-axis for turret 1; 12 stations and additional Y/Z axis for turret 2 (TNL 26 only); five or seven stations and additional X and Z axes on the front attachment; and five stations with additional X and Y axes on the backworking attachment. The fast 64 bit processor, TRAUB TX8i control, includes user friendly software that offers improved capability for operating and process optimization. The control is prepared for the Teleservice option. Also on display will be the MS32, a highly precise CNC controlled multispindle from the MultiLine Series. Three versions are available, based on the building block system: the MS32B, MS32P and MS32G.
