About this machine

This TOS WFQ 80 CNC Boring Mill is a used boring mill — sometimes referred to as a horizontal boring machine — designed for precision machining of large, complex workpieces requiring accurate bored holes, milled surfaces, and multi-axis contouring. Boring mills of this type are widely used in heavy engineering, mould and die making, energy, and general metalworking industries. TOS is a well-established Czech machine tool manufacturer with a long history of producing heavy-duty cutting and grinding machines for industrial markets worldwide.

The machine was retrofitted in 2008 and underwent a thorough inspection and refurbishment in 2024, making it one of the better-prepared used examples available. The 2024 refurbishment covered a comprehensive range of work: full cleaning and technical inspection, replacement of the Heidenhain TNC 426 CNC control system with new hardware, complete inspection of the electrical cabinet, replacement of damaged cables, repair of the control panel, full geometric accuracy restoration of the machine (with a geometric accuracy protocol available on request), inspection of the drives including new bearings for the X and Z ball-screw bearings, inspection of the headstock, inspection of the hydraulic unit, inspection of the lubrication system, and fitting of new telescopic covers. The machine remains live under power.

On the specification side, the working spindle carries a diameter of 128 mm and accepts tooling on a 50 ISO taper, with a spindle speed reaching 3,500 rpm. The work table measures 850 mm by 850 mm and is built to a robust design, rated to carry loads of up to 3,000 kg, rising to 5,000 kg with additional supports. A chip conveyor is fitted, and the machine runs Siemens motors and drives alongside the Heidenhain control. The machine is configured as a 4-axis CNC unit and is located in Germany.
