The heavily ribbed machine base made of a special casting has a substructure of hydraulic concrete. Damping elements between the machine base and substructure ensure good absorption of external vibrations. ■ Manually/automatically switchable longitudinal feed■ Proven mechanical system WHEELHEAD AXIS X Infinitely variable feed. The cross slide is equipped with a low-maintenance, hydraulic rapid approach mechanism. The preloaded, effectively covered needle guideways ensure a precise fine adjustment. Optionally available contact sensors enable a high contact speed and thus saves time. ■ Hydraulic...

■ Grinding between centers and live spindle grinding ■ High roundness accuracy The workhead enables grinding between fixed centers or live spindle grinding. The powerful workpiece spindle, which is relieved of belt tension, rotates in a hydrodynamic multi-surface plain bearing. Roundness during live spindle grinding is 0,0003 mm (0.000,012") as an option 0,0002 mm (0.000,008"). The workhead has a stepped drive with an AC motor. An infinitely variable drive with a frequency converter is optionally available. WHEELHEAD TAILSTOCK ■ Flexible ■ Internal grinding attachment The external wheelhead with...
