TNL18P
Sliding headstock automatic lathe with a diameter of up to 20 mm for turning with and without a guide bush.

- Simultaneous machining with up to 3 tools possible
- Easy change-over for turning operation with and without a guide bush
- Clearly structured working area with large axis travels
- Turret indexing using an NC rotary axis
- Very large pool of fixed and driven tools by using double and triple holders
- 3-axis grasping with counter spindle
- Excellent accessibility for operation and maintenance due to large sliding door
- Compact design at minimum footprint
- New TX8i-p production control
Kinematics

The TNL18P has 5 linear axes. In addition the Y motion evolves from X/C/H axis interpolation.
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 large X/Y/Z axis travels and 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 area

The working area of the TNL18P 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 TNL18P has a highly dynamic spindle belt drive 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 tooling circle corresponds to remarkable 1225 mm of Y-travel unwrapped, beating any linear tool carrier. The TNL18P 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.
