Applied developments

MOVING CROSS BEAM

Moving cross beam with working capacity as a controlled axis or locked axis. Guides mounted at a 90º angle which increases rigidity and distributes loads.

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.
