This TOS Varnsdorf WHN 13 is a used boring mill — sometimes referred to as a horizontal boring machine — dating from 1999 and currently located in France. Boring mills of this type are used for precision machining of large, heavy workpieces, performing operations such as boring, milling, drilling, and tapping on components that are too large or complex for conventional machining centres. TOS Varnsdorf is a long-established Czech machine tool manufacturer with a strong reputation for heavy-duty cutting and boring equipment, serving industries including energy, aerospace, rail, and general engineering.
This machine is equipped with a Heidenhain TNC 426 CNC control system, paired with an HR 410 electronic handwheel for manual override and precision input during setup or fine adjustment. The Heidenhain TNC 426 is a well-regarded contouring control capable of managing multi-axis simultaneous movements, making this machine suitable for complex three-dimensional machining tasks.
The axis travels are as follows: X-axis 3,500 mm, Y-axis 2,500 mm, Z-axis 1,250 mm, and W-axis (spindle quill) 800 mm. The rotary table measures 1,800 mm × 2,200 mm, providing a generous clamping surface for large workpieces. The spindle diameter is 130 mm, and the maximum spindle speed is 2,500 RPM. An external coolant system is fitted as standard.
The spindle has logged 15,600 working hours, which provides a useful reference point for assessing wear and remaining service life when evaluating this machine.
