PZS1212 CNC Drilling Machine for Industrial Plate. Usage & characteristics For steel tower, transmission tower, telecom tower,powder grid Flange drilling machine. Main Features of CNC sieve plate drilling machine a)  One or more movable slides are equipped on the cross beam of gantry , which are guided by two liner roller guide pairs and driven by servo motor and precise roller screw . b)  Vertical CNC feeding drills are equipped , and drills are driven by special conversion motor Stroke self-controlled drilling unit can make the drill approach work piece rapidly, when the drill touch the workpiece, it can change the feeding speed immediately to preset working speed automatically . After the hole is drilled through, the drill returns automatically and rapidly. c)  Heavy-load liner roller guide pairs are equipped on two sides of the machine worktable respectively. The longitudinal movement of the gantry's two sides is driven synchronously via AC servo motor and precise ball - screw .  Main Technical Data: ItemPZS1212PZS1616Max workpiece dimension  mm1200×12001600×1600Distance between the bottom of the spindle to work table mm60-280100-320Range of drilling diameterΦ1.5-Φ5Φ3-Φ10Type of drilling power headServo feed drilling headServo feed drilling headDrilling speed(feeding speed) mm/min(Common steel)(Stainless steel)50-22-(Common steel)30-120(Stainless steel)Quantity of drilling power head11(two spindles)Drilling axisOne or twoOne or twoType of spindleER20ER20 or Morse taper 3Motor power of power head2.24Max rotating speed of spindle98003000Vertical stroke of power head(Z axis) mm220220Servo motor power of Z axis kw1.01.2Longitudinal movement stroke of work table(X axis) mm12001600Servo motor power of X axis kw1.01.0Transverse movement stroke(Y axis) mm12001600Servo motor power of Y axis1.01.0Quantity of CNC axis33Total motor power KW1214Weight of the machine kgAbout 2500About 3000PZS1212 CNC Drilling Machine for Industrial Plate Videos
