The TOS WHN 13.8 is a used boring mill — sometimes referred to as a horizontal boring machine — a type of precision machine tool designed for machining large, complex workpieces by boring, milling, and drilling with high positional accuracy. TOS is a well-established Czech manufacturer with a long history of producing heavy-duty machine tools, including horizontal boring and milling machines widely used in general engineering, energy, shipbuilding, and the production of large structural components.
This machine was built in 1996 and is currently located in Germany. It is configured as a 5-axis machine and is equipped with a Heidenhain TNC 426 CNC control unit, a highly regarded digital contouring control known for its reliability and precision in multi-axis machining applications. The spindle taper is ISO 50, a robust standard suited to heavy-duty cutting work.
The working spindle diameter measures 130 mm, which indicates a substantial, rigidly built spindle assembly capable of handling demanding cuts in hard materials. Axis travels are generous: X-axis travel extends to 3,500 mm, Y-axis travel to 2,000 mm, and Z-axis travel to 1,250 mm, providing a large working envelope well suited to oversized components.
The machine is fitted with a rotary table whose clamping surface measures 2,200 × 1,800 mm, offering ample area for securing large workpieces. The rotary table is rated to support a maximum workpiece weight of 12,000 kg, confirming the machine's suitability for heavy industrial applications where substantial castings, housings, or structural parts need to be repositioned and machined on multiple faces in a single setup.
