GDM Series
- GDM Series gantry type machining center is a new generation with portal fixed and table moving. Adopting a modularized design, changeable worktable and spindle(5-face machining of special spindle) can manual and automatic change according to customers’ requirements. This machine can be applied to parts of rough and finish machining, large and medium size, mould and shape of plate,disc,shell,chest or curve surfacing as well.
- GDM series have high working performance with suitable specifications, which are high reliability, high precision and high rigidity.
- GDM gantry type machining center adopts a configuration design of fixed portal frame, combined with a moving table on X-axis, so integrate a large space and maximum rigidity. The Z-axis “spindle” is designed to move out of table to widen machining range.
