Gantry Type Machining Center

Yama Seiki offers the Awea LG Series gantry type machining center, which combines the gantry style structure with adjustable crossbeam mechanism, high horse power and rigid features for extra-large workpieces. Awea's LG series machines are suited for aerospace, naval engineering and energy applications.

The LG Series comes with either a modular gear or built-in type spindle design, providing a range of different cutting features. The modular gear spindle is constructed with a unique head design allowing the spindle, spindle motor, ball screw and dual hydraulic counter weight cylinders to be symmetrically placed, thereby preventing thermal distortion and minimizing deflection. This will help ensure accuracy and provide heavy-duty cutting capability.

Awea offers powerful cutting capability with an inner-rail embraced structure providing high rigidity and good stress flow. This minimizes overhang and vibration issues. The Y-axis roller type linear guide ways are built offset from each other, increasing structural rigidity and reducing the distance between the spindle and cross beam, which enhances overall cutting performance.

"Combining our modular design concept and exclusive patented technologies, the LG series provides superior machining performance for large workpieces," said a company spokesperson. "The heavy-duty working table is constructed with a rigid double layer structure design. It can easily endure super heavy workpieces without deformation, and its floor-type design allows the working table to firmly attach to the base, which effectively dampens machining vibration while continuing to ensure accuracy."

The spokesperson continued, "The LG-20070 is the first super large machining center ever introduced with a 7,000 mm cross span among Taiwanese manufacturers. AWEA's patented design has successfully overcome the physical limits other machine tool builders continue to struggle with, minimizing the deformation caused by the weight of the 7,000 mm super wide crossbeam, while ensuring optimal machining accuracy."

The LG series can be equipped with self-developed milling heads, automatic head storage magazine and vertical/horizontal ATC system to provide high added cutting capabilities for large workpieces.
