Bridge girders and welded structures drilling
The Enterprise, is an automatic CNC multiple spindle gantry drilling line that features an innovative laser probing process for the productive processing of welded bridge girders and welded structures. The gantry can accommodate either long structures or multiple short parts with loading and unloading in masked time. This expansive processing window, with laser scanning process, can eliminate the laydown procedure and manual drilling in the fabrication of bridge girders that are frequently cambered or curved. The exceptional size capability also lends itself to process box girders, trusses, and large welded structures.
An automatic CNC controlled device, with triple laser, is used to detect the real location of the structure to position holes, for example, relative to the actual position of the part to be processed.
Three direct drive independent drilling spindles delivers the motors full power to the tool.
These three high-tech spindles can operate simultaneously on both flanges and the web even when the operations in each face are offset.
Each spindle is equipped with an additional auxiliary axis which generates an extra stroke to carry out countless operations by keeping the material clamped in position. This translates into greater flexibility and unequalled productivity.
Thanks to a technologically advanced concept, the vertical spindle is able to rotate to easily mill the ends of profiles.
The powerful direct drive spindle ensures high drilling performances. This heavy duty, yet simple design, makes this spindle the most efficient and advanced on the market today.
Thanks to the sophisticated spindle design, the full capabilities of carbide tooling can be realized.
The automatic tool change system is managed by the CNC and is equipped with 6 positions on each spindle.
All our systems are supplied in accordance with the highest safety standards and regulations.
