GDM1220 cnc double column gantry machining center
High Accuracy
All X, Y, Z axes using optical encoder scale technology, forms a closed machining system, which increases the machining accuracy. Highly rigid worktable moves on a machine base made with one piece of casting, which ensures the rigidity of the whole machine. In addition, Finite Element Analysis has been applied in the machine engineering stage to optimize the structure of the machine and enhance the rigidity.
