Design features
X-Axis
Slide for column with hydrostatic guideways on low-friction guideway plates. Drive system with Servomotor, Duplex-Pinions and Gear Rack. The pinions are pretensioned hydraulically for zero axial play.  
Spindle unit
The high-precision RAM, made of meehanite cast iron in a rectangular shape, slides on hydrostatic wedge bars machined directly into the head unit. Inside the RAM runs - axially on bronze bearings - the boring quill. It is supported by front and rear angular contact ball bearings in high precision design.
