Two Spindle CNC Gundrilling Machine

Two spindle CNC gundrilling machine

Machine brief:

 

1.1 Processing Capacity :

Drill diameter range: Φ4~Φ30mm

Max. Drill depth :500mm

Max. Hole length-diameter ratio : 100:1

Max. Workpiece OD diameter: Φ200mm

1.2 Gun drilling processing method, double spindle structure,can drill two workpieces at the same time ,suitable for drilling the coaxial hole on shaft parts.

1.3 When drilling ,both workpiece and cutting tool rotate in opposite directions, cutting tool feeding . Used for drilling the coaxial hole on shaft parts .

1.4 Workpiece clamping:

The chucks are mounted in front end of spindle of headstock and the conde dishes are mounted in the front end of guide frame, the hydraulic system control the headstock spindle to move axially, use the chuck on the headstock side, and chamfer on end of workpiece (guide frame side)to clamp and position the workpiece .

1.5 The machine adopts linear guide rail .

1.6 CNC system :SIEMENS 808D

1.7 Drill box:

Adopt the servo main motor driving the spindle to rotate through synchronous belt and synchronous belt wheel, speed stepless could be realized , the max. rotary speed of spindle is 5000r/min ; One motor drives two spindles to rotate . The spindle driver front-located, good for protecting the main motor, and convenient for changing the cutting tool .

1.8 Headstock:

Drive the workpiece to rotate, rotary speed is constant 120r/min;The spindle can move axially under the control of hydraulic system to tighten and loosen the workpiece ; The spindle driver front-located, good for protecting the main motor, and convenient for changing the cutting tool .(the below pic is for your reference, your machine is with 2 chucks)

 

1.9 Cutting tool feeding system:

Adopt the structure of servo motor driving ball screw, the cutting tool feeding speed stepless could be realized .

1.10 Drill bar support rest :

2 sets , the movement between drill bar support rest and drill box is linked; The distance between drill bar support rests is equal when the drill box locates in any position.

1.11 Coolant system :

Mainly composed of high pressure pump groups, chain plate chips conveyor, oil chiller,filter device and so on . The pressure adjustment knob and flow adjustment panel of the coolant system are installed on the CNC system operation station .

1.12: The machine bed ,box body etc. basic parts are cast by resin sand, through twice aging treatment.The machine bed is designed with slant oil returning slot , so that the cutting oil will not be stored, could return to the oil tank quickly .

1.13 Guide frame:

Used for guiding the cutting tool , discharge cutting chips , supporting the drill bar . The guide sleeve is assembled on its front end , used for guiding the cutting tool ; The drill bar support sleeve is assembled on its rear end, used for supporting the drill bar .
