Spinner expands multi-turret lathe range

German machine tool manufacturer Spinner Werkzeugmaschinenfabrik, which builds CNC lathes and machining centres in its Sauerlach factory near Munich, has increased its TTS turn-milling centre range. Expanding the size of bar or billet that can be handled, the new 85 and 125 models join the 42 and 65 multi-tasking lathes introduced towards the end of 2021, which are already on their second-generation upgrade. Sole sales and service agent in the UK and Ireland is Kenilworth-based Whitehouse Machine Tools.

Launched at EMO 2025 in Hannover, the TTS 85 and TTS 125 turning centres each have a pair of powerful motor spindles with a bar capacity of 85mm (80kW/930Nm) and 125mm (67kW/1,254Nm) respectively. Chucking of billets up to 500mm diameter is possible and may be carried out in the sub spindle concurrently with bar working at the main spindle. A tailstock can be specified if a twin-spindle machine is not needed.

Flexible, modular design allows configurations with two, three or four turrets to meet a user’s precise machining requirements. TTS-Duo, TTS-Duplex and TTS-Twin are different two-turret setups, with the option of a steady-rest (or two) positioned below the spindle centreline. TTS-Triplex has three turrets, with or without a steady rest, while TTS-Quadrex is a four-turret configuration. Tool carriers above the spindles have ±100mm of Y-axis motion, while those below do not.

The robust, servo indexing turrets are available with 16 or alternatively 12 positions, all of which are live, and use BMT45 or BMT65 tool holders to ensure maximum cutting performance and accuracy of tool exchange. Driven tool power is 15kW, torque is up to 82.7Nm and the standard 4,000rev/min maximum rotational speed may be doubled on request.

The machines are offered in two bed lengths with a maximum distance between the spindle noses of 1,500 or 2,100mm. An 80-bar coolant delivery system with temperature control are further individual options. All core parts of the lathes, including the motor spindles and turrets, are produced at the Spinner factory and robotic component load/unload and storage arrangements are similarly manufactured in-house.
