The bed with two guide ways of box-type design is made from high-grade pearlite cast iron. Double-V guide ways, along with the inner V-way for tailstock, are induction hardened and ground. The heavy-ribbed bed is double walled. In that way we substantially minimize vibration and improve finishes.
The headstock is of a modern compact design. The heavy duty spindle is supported in the front with one double-direction angular contact thrust ball bearing and one double-direction angular contact thrust ball bearing on the back side. This system allows using big spindle bores while keeping high precision, rigidity for heavy loads, high turning speed and superior surface finish.
The main spindle is powered by a Siemens AC variable speed 18,5 kW motor (S6). The power is transmitted to the spindle by means of multi-V power belt. To ensure a high turning torque at low rpm, the machine is equipped with a 2-speed planetary gearbox. The gear change is automatic.
This specially extended neck allows more clearance between the tailstock body and the cross slide. This design permits a better access for machining parts close to the tailstock center. The extra-large 100 mm diameter quill is hardened and grounded and has MT 5. The tailstock can easily be positioned by carriage using a quick-disconnecting coupling. Only one cam lever clamps and unclamps tailstock to the bed. A hydraulically operated tailstock quill is available as option.
