PZ5050G CNC High-Speed Drilling Machine for Tube Plate.  Product feature:  1. The machine can use not only hard alloy innercooling drilling head to drill with high speed, but also high-speed steel twist drilling head.  2. It also has the function of milling straight groove slightly. Processing is CNC controlled, very convenient to operate, Automation, high precision, variety, medium and small batch production can be realized.  3. The machine is mainly composed of bed (worktable), gantry, vertical ram-type drilling spindle, hydraulic system, cooling system, auto-lubricating system, CNC system, electrical system and chip-conveyor etc.  4. Two movable slides are equipped on the cross beam of gantry. The slides are guided by two linear roller guide pairs and driven by AC servo motor and precise ball screw pair of big pitch respectively which are located between the two guideways.  5. The slides on the cross beam are equipped with vertical CNC feeding ram-type drilling spindle, which adopts special conversion motor with heavy load for spindle.  6. The motor drives the spindle via synchronous belt. The drilling spindle adopts Taiwan precision spindle (innercooling) with disk spring automatic broach mechanism, hydraulic cylinder loosing cutter, very convenient to change shank.  7. The machine is equipped with hydraulic system to finish the hydraulic balance of vertical ram and hydraulic cutter loosing of spindle.  8. It is equipped with chain-plate type automatic chip-conveyor and chip-conveyor and chip collection trolley. The cooling system is equipped with paper filler, high-pressure innercooling pump and low-pressure outercooling pump, which are used for innercooling or outercooling of cutter.  Double-spindle drill at the same time, high efficiency.  Two kinds of drilling heads, BTA or gun drill.  Can clamp workpiece of Φ4000mm,drill hole of 750mm.  Recycle use of the coolant liquid, air cooling equipment imported from German.  Main Technical Data:ModelPZ3030GPZ4040GPZ5050GPZ6060GMax workpiece      dimension(mm)Max drilling center to center distance(LxW)(mm)3000x30004000x40005000x50006000x6000Max plate thickness(mm)300300300300Work tableT-slot width(mm)28282828Drilling power headQuantity2222Main spindle taper holeBT50BT50BT50BT50Max drilling diameter(mm)Φ40(hard metal drill)Φ40(hard metal drill)Φ40(hard metal drill)Φ40(hard metal drill)Main spindle rotating speed(frequency conversion stepless)(r/min)30-200030-200030-200030-2000Main spindle motor power(KW)2x222x222x222x22The distance between lower part of main spindle to the work table(mm)150-750150-750150-750150-750Gantry longitudinal movement(X axes)Max stroke(mm)3100410052006200X axes movement speed(m/min)0-80-80-80-8X axes servo motor power(KW)2x32x32x32x3      Power head horizontal      movement(Y axes)Max distance between      two main spindles(mm)3100410052006200Y axes movement speed(m/min)0-80-80-80-8Y axes spindle motor power(KW)2x32x32x32x3Vertical slip-way feed-in movement(Z axes)Max stroke of Z axes(mm)600600600600Z axes feed-in speed(mm)      Z axes spindle0-40000-40000-40000-4000servo motor power(KW)2x32x32x32x3Positioning accuracyX,Y axes(mm)       ≤0.1(over all length)≤0.1(over all length)≤0.1(over all length)≤0.1(over all length)Repositioning accuracyX,Y axes(mm)≤0.5(over all length)≤0.5(over all length)≤0.5(over all length)≤0.5(over all length)Hydraulic systemPressure of hydraulic pump/flow(L/min)7/257/257/257/25Hydraulic pump motor power(KW)3333Chip removal and coolingForm of clip removalFlat chainFlat chainFlat chainFlat chainQuantity of chip removal2222Speed of chip removal(m/min)1111Chip removal motor power(KW)2x0.752x0.752x0.752x0.75Cooling pump motor power(KW)2x3+0.752x3+0.752x3+0.752x3+0.75Total motor power(KW)75757575Outline dimension(LXWXH) (m)About 7.2x6.0x3.5About 8.2x7.0x3.5About 9.2x8.0x3.5About 11x9.2x3.5Machine weight(t)About 35About 48About 55About 60PZ5050G CNC High-Speed Drilling Machine for Tube Plate Videos
