Product Details


In order to improve the manufacturing efficiency of automobile molds made by gantry milling machine, Bridge gantry CNC machine tool adopts an elevated bridge beam structure with a fixed table in design, which changes the shortcomings of ordinary gantry milling machines that cannot carry large workpieces, the worktable is cast in one piece, which ensures the rigidity of the machine tool, and the internal stress is eliminated by secondary tempering after the rough machining of the casting, which ensures the stability of the machine bed in the process of machining large molds .

Improve the manufacturing efficiency of automotive molds:

Bridge gantry CNC machine tools and gantry CNC drilling and milling machines use high-priced bridge-type moving beam structures with fixed worktables in design. Increased fast movement speed, enhanced stability.

Loading large workpieces:

The whole bed, column and worktable are cast in one piece, which ensures the rigidity of the lathe, and the internal stress is eliminated by secondary tempering after rough machining of the casting, and the stability of the pillow bed in the process of machining large molds. (10 tons/square, theoretically 16 tons/square)

Preserve precision:

In the design, a four-track dual-drive high-speed transmission mechanism is adopted, and the transmission accuracy is stable and reliable. Suitable for the processing and manufacturing of precision automobiles and large mechanical parts

Mainly for machinable materials:

Precision auto molds, large mechanical parts
