This TOS WHN 13.8 is a used boring mill — sometimes referred to as a horizontal boring machine — designed for precision machining of large, heavy workpieces through boring, milling, drilling, and related metal-cutting operations. TOS is a well-established Czech machine tool manufacturer with a long history of producing heavy-duty metalworking equipment for industrial and engineering applications worldwide.
Originally manufactured in 1980, the machine was retrofitted in 2001 and subsequently refurbished in 2024, and it is currently live under power. The 2024 refurbishment was extensive: it included a full cleaning of the machine, checking and adjusting the machine geometry, regrinding of the spindle cone, a functional check, revision of the electrical equipment, revision of the hydraulics and lubrication system, adjustment of clearances and optimisation of the drives, replacement of the guide surface wipers, repair of the telescopic machine cover, replacement of the balancing ropes, repair of the platform, and revision of the cooling unit (CHZ13). A replacement spindle is also available as an option for an additional fee. The machine carries a six-month warranty on mechanical parts.
The boring spindle has a diameter of 130 mm and a clamping cone of ISO 50, with a maximum spindle speed of 2,500 rpm. The machine operates across four axes and is equipped with a Heidenhain 426 control unit, with Siemens motors and drives throughout. The square work table measures 1,800 mm in length by 1,800 mm in width and is rated to carry a load of up to 12,000 kg, making the machine well suited to large and heavy component work.
The machine is located in Germany.
