Both tool carriers have large X/Y/Z-axis travels. The tool carriers are a highlight of the machine design because the rotary motion is executed by an NC axis without any mechanical locks. This allows to position both turrets very fast at any angle. The counter spindle with integrated lower turret positions on 3 axes resulting in ultimate transfer accuracy. The vertical machine bed design guarantees a favorable chip flow.View into the work area1 / 4 Up to 3 tools being used simultaneously The working area of the TNL18 is easily accessed by the user through its noticeably high and wide sliding door. It is clearly structured by the components: Main Spindle, Upper Tool Carrier, Counter Spindle with Lower Tool Carrier and Rear End Machining Unit. The main spindle of the TNL18 has a highly dynamic motor spindle in synchronous design and fast acting C-axis positioning. The smart headstock design with large Z-axis travel allows the turning operation both with and without a guide bush. The upper tool carrier has 8 tool stations with powerful tool drive and internal coolant. The upper turret of the enhanced TNL18 has compared to the P variant all 3 axes X/Y/Z. This independent Z-axis enables applications like thread chasing without material return or deep hole drilling simultaneously to backworking without workpiece retraction into guide bush. The tooling circle corresponds to remarkable 1225 mm of Y-travel unwrapped, beating any linear tool carrier. The TNL18 has a powerful counter spindle with large X/Y/Z axis travels and integrated tool carrier with 7 stations. Each station can be equipped with multiple holders thus leading to a large pool of tools. 7 stations at the rear end machining unit, 4 four of those with internal coolant, enable complex backworking at the workpiece
