Up to four tools can be used simultaneously and independently of one another. What is innovative of a fixed headstock automatic in this size class is the fully functional Z-axis in the main spindle, which, in terms of control technology, is coupled to the bottom turret. This means that each tool system has an axis in the X and Z direction. In its basic version, the machine is equipped with a moveable headstock and a bottom tool carried fitted with X- and Y-axes. In the extended version, a counter spindle of identical design to the main spindle has been arranged coaxially to the main spindle. To allow the top tool turret to work independently, it is equipped with a Z-axis. However, the version considered near to perfect is the one that has mobile so-called front working and backworking attachments for the main and counter spindles. In this version, the outer contour is usually machined using the turrets, while the inner contour is machined at the end face or front face by the already mentioned front working attachment. Once the workpiece has been completed on one side, it is picked up by the counter spindle. The counter spindle then moves to the backworking attachment, allowing the complete machining of the rear to proceed. View into the work area1 / 2 Work area of the TNL26K The TNL26K has lots of highlights to offer. Thus, main and counter spindles have absolutely identical designs and have been constructed as liquid-cooled motor spindles in synchronous technology. Their motor powers of up to 10.7 kW are unique on the market and substantially exceed those of comparable drives. Increased power is also provided by the tool drives at 5. 5 kW. This is particularly advantageous for complete machining. In the past, users have often used sliding headstock automatics for producing short turned parts, owing to the higher productivity. However, the guide bushing had always interfered in this. The company from Reichenbach has now come up with an innovative design that allows the guide bushing to be omitted entirely. The absence of a guide bushing gives the user, of course, an entire series of advantages. On the one hand, there is no need to use a high-precision bar stock (grade up to IT11), and the bar remnants are much shorter. On the other hand, setup times and costs can be lowered enormously. The setup of the guide bushing is, of course, also dispensed with. Despite the highlights mentioned, the TNL26K has a very compact design and is readily accessible from both sides. The extremely fast TRAUB TX8i-s 64-bit control has the following standard features: visual control of the geometries, work sequence, collision (2D simulation) and user-oriented software for use, operation and optimization at the machine
