CNC GANTRY MACHINING CENTER
Gantry Type 5-Face Machining Center GDLG-8050
GooDa GDLG 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.
High Rigidity Structure
Complete product line with full range specifications, the GDLG 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.
Powerful Cutting Capability
Modular gear or built-in type spindle design provides different cutting features, to meet with various types of cutting needs.
2,500 kg/m² heavy-duty fixed working table could meet with all sorts of working conditions for large work pieces.
Floor type tool magazine with speedy tool change is placed on the back of the machine to provide easy operation and maintenance.
High Speed, High Torque Built-in Motorized Spindle
Super large separate type coolant tank and two rotating chip augers on both sides of the working table, allows easy maintenance and efficient chip removal while maintaining coolant performance.
This series CNC Machining Center could be equipped with automatic head changer and vertical / horizontal ATC system to provide maximum efficiency as of a 5-face machining center.
Gantry type structure design provides optimal stable dynamic accuracy and the space usage is 40% less than bridge type models.
