NEW YAMA SEIKI LG6050
Overview
Gantry Type Machining Center
Introducing YAMA SEIKI with mature manufacturing abilities and advanced technology skills, the LG series gantry type machining center combines gantry type structure with adjustable crossbeam mechanism, strong horse power and high rigidity features, to provide you with a complete machining solution for extra large work pieces. It has been widely used in aerospace, shipbuilding, energy and machine tools industries.
The LG series could be equipped with automatic head changer and vertical / horizontal ATC system to provide maximum efficiency as of a 5-face machining center.
Complete product line with full range specifications, the LG series could be equipped with self-developed milling heads, automatic head storage magazine and vertical / horizontal ATC system to provide high added cutting capabilities for large work pieces.
High Rigidity Structure
Combining our modular design concept and exclusive patented technologies, the LG series provides you with superior machining performance for super large work pieces. The LG-20070 is also the first super large machining center ever introduced with a 7,000 mm ( 275.5″ ) cross span among Taiwan manufacturers.
Adjustable Crossbeam Mechanism ( Patented )
YAMA SEIKI’s patented design has successfully overcome the physical limits, minimizing the deformation caused by the weight of the 7,000 mm ( 275.5″ ) super wide crossbeam, while ensuring optimal machining accuracy.
