GZP3030,GZP4040,GZP5050,GZP6060 CNC High Speed Plate Drilling Machine

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'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 ,separately driven through synchronous belt (i=2) and precision coarse pitch roller screw pair , which is driven by AC servo motor , ensure working high precision4. Drilling power head of this machine adopts rigid precision spindle (BT50 inner cooling precision spindle), can equipped with inner cooling carbide drill bit , with high precision . Equipped with the hydraulic cylinder for tools changing, loading and unloading of tools easily. Spindle is driven by high-power spindle servo motor through synchronous belt, spindle rotation speed 30 ~3000r/min, a wide speed range.5. Vertical ram is cast structure, and Z axis moving adopts two linear roller guideways guiding, driven by AC servo motor through synchronous belt (i=2) and transmitted by precision ball screw.6. The pneumatic system is mainly used to blow the spindle center and clean the spindle taper. Gas blown in from the front spindle to prevent dust from entering the inside of the spindle group.Specifications：Item UnitsGZP30GZP40GZP50GZP60Workstable Workstable sizemm3000×3000-240004000×4000-240005000×5000-240006000×6000-24000Distance between columnsmm4000490059006900Max.load capacityt/m²10101010T-slotmm28282828Vertical ram type drilling headQuantityPcs2 standard2 standard2 standard2 standardTaper hole of spindle BT50BT50BT50BT50Max. drilling diametermmφ60φ60φ60φ60Drilling depth/diameter ≤5 (Carbide drill)≤5 (Carbide drill)≤5 (Carbide drill)≤5 (Carbide drill)Spindle rotation speedr/min30—2800standard30—2800standard30—2800standard30—2800standardSpindle motor powerkW22/33standard22/33standard22/33standard22/33standardMax. spindle torque（n≤600r/min）Nm350standard350standard350standard350standardDistance between spindle and Workstablemm300-800standard300-800standard300-800standard300-800standard（X axes） Longitudinal Movement of GantryMax.strokemm3000-240004000-240005000-240006000-24000Moving speed of X axism/min0-100-100-100-10servo motor power/ torquekW/ Nm3/28.43/28.43/28.43/28.4（Y axes） Transverse Movement of Drilling headMax.strokemm3000400050006000Moving speed of Y axism/min0-100-100-100-10servo motor power/ torquekW/ Nm3/28.43/28.43/28.43/28.4（Z axes）Feeding of Vertical ramstrokemm500500500500Moving speed of Z axism/min0-50-50-50-5servo motor power/ torquekW/ Nm3/28.43/28.43/28.43/28.4Positioning precisionX axismm0.06/20000.06/20000.06/20000.06/20000.03/2000 With optical scale0.03/2000 With optical scale0.03/2000 With optical scale0.03/2000 With optical scaleY axismm0.08/whole length0.08/whole length0.1/whole length0.1/whole length0.04/whole length With optical scale0.04/whole length With optical scale0.05/whole length With optical scale0.05/whole length With optical scaleRe-positioning precisionX axismm0.03/20000.03/20000.03/20000.03/20000.015/2000 With optical scale0.015/2000 With optical scale0.015/2000 With optical scale0.015/2000 With optical scaleY axismm0.04/whole length0.04/whole length0.05/whole length0.05/whole length0.02/whole length With optical scale0.02/whole length With optical scale0.025/whole length With optical scale0.025/whole length With optical scaleHydraulic systermHydraulic pump pressureMPa6.5Hydraulic pump fluxL/min25Motor power of pumpkW3Swarf cleanerType of Swarf cleaner Plate chain typeQuantity of swarf cleanerPcs2Swarf cleaning speedm/min1Motor powerkW2X0.75Cooling systermMotor power of innerkW2×3Motor power of outerkW0.75Centralized lubricationPressureMPa2Oiling quantitymL0.1Electrical systermCNC systerm FAGOR8055No.of CNC 6Total motor powerkWAbout 90
