4-spindle CNC Gundrilling Machine

4-spindle CNC gundrilling machine

    

Machine brief:

 

1.1 Processing Capacity :

Drill diameter range: Φ3~Φ20mm

Max. Drill depth :1500mm

Max. Hole length-diameter ratio : 100:1

Workpiece OD range: Φ15~Φ100mm

1.2 Gun drilling processing method, FOUR spindle structure,can drill FOUR workpiece 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 manual three-jaw chuck on the headstock holds one end of the work piece, and the cone on the oil pressure head automatically pushes the chamfer on the other end of the work piece.

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 ; TWO motor drives FOUR 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 at a constant speed of 117r/min; The spindle can be moved axially under the control of the hydraulic system for jacking or loosening the workpiece. Spindle drive front, convenient loading and unloading of workpieces, help protect the main motor.

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 .
