Heavy conventional lathe
Powerful turning technology for large and long workpieces
The PICOtre T was developed for demanding machining tasks that require high stability, large workpiece capacities, and direct manual operation.
The massive monolithic machine bed provides a stable foundation for medium to heavy workpieces. Center distances of up to 10,000 mm also allow for the machining of particularly long shafts and rotationally symmetrical components.
Despite its size, the machine can be operated precisely and sensitively using mechanical handwheels. This makes it particularly suitable for repair shops, heavy machine construction, and individual part manufacturing.
Monolithic, generously sized machine bed
For heavy and long workpieces
High performance across the entire speed range
Direct and controllable manual operation
Large dimensions. Precise control.
Heavy machine construction combined with sensitive conventional operation.
Construction and technology
Designed for demanding machining tasks
Generously sized cast components, high-quality spindle bearings, and a powerful drive form the basis of the PICOtre T.
Automatic three-speed gearbox
An automatic gearbox with three ranges is combined with stepless speed control via a frequency converter. This provides high performance even at low speeds.
Precision bearings from Timken or SKF
The precision-ground main spindle is guided in high-precision bearings and designed for high loads as well as precise roundness.
72 feeds and 54 thread pitches
The closed, oil-bath lubricated Norton gearbox offers numerous longitudinal and cross feeds as well as metric, Whitworth, module, and diametral pitch threads.
Stable and precisely hand-scraped
The generously sized main slide is hand-scraped for optimal fitting to the machine bed and is equipped with adjustable wedge strips.
115 mm spindle with MK 6
The robust tailstock features a hardened and ground spindle with a diameter of 115 mm, a stroke of 300 mm, and a Morse taper MK 6.
Machine details
Direct operation despite large machine dimensions
The clear arrangement of the controls facilitates the setup and machining of large workpieces.
Heavy slide package
Generously sized guides and handwheels enable stable cuts and controlled feed movements.
Massive tailstock
The tailstock reliably supports long and heavy workpieces during machining between centers.
Monolithic machine base
The wide, heavy substructure ensures high stability for long and heavy workpieces.
