design features:

Machine
Backlash-free ball screws in all linear axes
Direct, absolute measuring systems in all axes, make HEIDENHAIN

Machine bed
Wide, heavily ribbed steel construction, 4-lane bed
Preloaded compact roller linear guides for backlash-free guiding of the slides
Bed and column are rigidly connected

Machine column
Solid ribbed cast iron column in box construction
Preloaded compact roller linear guides for backlash-free guiding of the headstock

Headstock / Drilling spindle
Rigid cast iron construction
Bearing of the spindle system with preloaded precision angular contact ball bearings with
lifetime lubrication mounted in preloaded fixed spindle projection
Automatic switching of the two speed series via primary gearing with hardened
gears and oil cooling
Power transmission to the boring spindle through low-noise precision V-ribbed belts
Nitride-hardened, precision-balanced drilling spindle, axially adjustable, positionable at any angle
and protected against chips and coolant by a spindle labyrinth

Table group
Cross-sliding and rotating clamping table in cast iron design with preloaded compact roller linear guides with high rigidity for longitudinal and transverse adjustment, together with headstock vertical adjustment guarantee stick-slip-free circular interpolation.
