Performance Characteristics
  • The gantry machining center is mainly used for processing large parts such as plates, discs, housing parts and molds with high precision, many processes and complicated shapes.
  • GMC series gantry machining center adopts fixed beam double-column gantry frame structure, cross layout, and the machine tool is stable and reliable. The headstock adopts a nitrogen cylinder balancing mechanism to ensure the smoothness of the headstock moving up and down along the sliding saddle.
  • The bed, workbench, column, beam, sliding saddle, headstock and other large parts are made of high-strength cast iron material, which is made of resin sand.
  • The two aging treatments eliminate stress and effectively inhibit the deformation and vibration of the machine tool caused by cutting force.
