Construction system:

This series integrates the fix table and mobile bridge system supported by two raceways with the Gantry system.

The construction system used in this model makes this machine especially designed for working on voluminous tridimentional workpieces. Its structure offers a great precisión without vibrations, it’s designed for light materials machining.

With a longer course for the “Z” axis, it enables us to machining curved items, with the possibility of installing heads with 4 or 5 axis.

Concerning the fixation of the workpieces, we can chose an electro-welded table made of steel, a slotted foundry table or a resin table with the vacuum system incorporated.

Machine entirely protected and covered which offer the option to be soundproof, also to facilitate the loading of large and/or heavy items, the table is stable and as well relatively near the ground.

The robustness of the structure allows high speeds of movement of the axes and excellent finishes.


• Measures of work on demand.
• Fixing table for steel, electro-welded or resin parts
• Double motor in the displacement axes, master / slave
• Installation of linear rules
• Protection bellows on all axes
• Different spindles, powers and formats adaptation
• Various models and tool change storage capabilities
• Different work areas, double table, pendular work choice
