Weiler’s new four-way bed lathe is for machining long, thin workpieces.

Weiler Werkzeugmaschinen GmbH introduced a four-way bed lathe to machine long, thin workpieces without reclamping. The Emskirchen, Germany-based company’s new V series includes the V90 and the V110. Both lathes feature automated cycles and digital drives. The V90 has a swing over the bed of 940mm (37") and a swing over the cross-slide of 590mm (23.22"). The larger V110 has a swing over the bed of 1,160mm (45.6") and a swing over the cross-slide of 810mm (31.88").

The main spindle is available with spindle bores of 165mm (6.49"), 262mm (10.31") or 362mm (14.25") and is driven through two different gear stages with a power output of 45kW/37kW (60 percent/100 percent duty cycle). This enables the main drive on the spindle to reach maximum torques of 8,300 to 11,400 Nm and feed forces of 20 kN, according to the company.

The V90 and V110 have a longitudinal drive with ballscrews powered by a three-phase drive that can support a distance between centers of up to 6,000mm (236.22"). The models with larger turning lengths have a rack-and-pinion drive with prestressed pinions and a direct-path measuring system.
