GZP3030,GZP4040,GZP5050,GZP6060 CNC high speed plate drilling machine?I. Machine application:Gantry movable CNC drilling & milling machine ,with the function of drilling ,tapping and slight-milling ,can clamp carbide drill inner-cooling or high-speed metal twist drill outer cooling . Mainly used in the processing of flange, heat-exchanger, tube sheet. the processing controlled by CNC, with high efficiency , precision, easily programming and simple operation. The machine structure and configuration:This equipment includes main bed and longitudinal sliding stable gantry, transverse sliding table, the vertical ram drilling power head, chip conveyor, hydraulic systems, cooling systems, centralized lubrication systems, electrical systems, pneumatic systems and other components.1. This machine is gantry movable drilling machine, reducing the bed length, saving floor space.The bed and beam are steel plate welded , through the weld artificial aging treatment, that ensures the stability and accuracy of machine .The gantry beam through the limit-element analysis by well-shaped way, let the machine& acute;s static and dynamic stiffness greatly improved, great resistance bending and twist effect , can guarantee large cutting parameters. Worktable is equipped with a number of transverse T-slot to clamp the clamping tools and workpieces.2. The longitudinal (X axis ) movement of gantry is guided by horizontally installed high precision linear rolling guide pair installed on side machine body ,with moving flexible. Adopting precise ball screw pair on both side of machine work synchronously by servo motor drive. Cleaning up the gap between guideway, with good co-working and high precision positioning. Two sides driving synchronously ensure the parallel movement of gantry and the vertical of Y axis to X axis in any directions. 3. The transverse (Y axis ) movement of drilling power head is guided by two sets of NO. 65 high precision linear guide pair installed in front of gantry beam ,separa
