Applied developments

CARRIAGE - RAM

Double ball screw and double compensation system in the vertical drive. Symmetric system, greater thermal stability.

CROSS GUIDING SYSTEM

2 linear guides for cross guiding system mounted on the cross beam forming a 90º angle, increase rigidity, distribute the loads and position the ram closer to the cross beam.

VERTICAL GUIDEWAYS BOX IN BOX

Prismatic guideways and roller packs with adjustable preloaded.
