Gun Drilling Machine of Single Spindle

1.Gun drilling Machine brief

Drilling range ：Φ3～Φ20mm( vairously hole size is available)

Max. Drilling depth ：500mm/1000mm/4000mm

Max.hole length-diameter ratio :100:1

Workpiece OD range ：Φ15～Φ100mm

Gun drilling method,single main spindle,double main spindle or four main spindle structure,which could drill one or two or four workpieces at the same time.

When drilling,both the cutter tool and workpiece will rotate relatively,tool infeed.

Workpiece clam：Equips with coned disc in the front of the main spindle of the headstock and guide rest,the headstock will do axial movement under the hydraulic system control,utilize the coned disc and two ends chamfer of the workpiece to clamp and positioning the workpiece automatically;  

The machine equips with linear guide rail.

CNC control system: Single or double spindle  SIEMENS-808D，Four spindles SIEMENS-828D

Drill bar box: used to drive the cutter tool rotate,adopts servo main motor to drive main spindle rotating thought synchronous belt and synchronous belt wheel,which can realize stepless speed adjustment; main spindle max rotating speed 6000r/min, main motor power: single spindle 3.7kw,double spindle 7.5w(one motor drive two main spindle rotating),four spindles 7.5kwx2(one motor drive two main spindle rotating)

Cutter tool infeeding system:used to drive the cutter tool axial movement; adopts servo motor to drive the ball screw though coupling,which can realize stepless speed adjustment.   

Coolant system: Provide cutting oil to the cutter tool, Filtering and coolant the cutting oil. Consists of high pressure pump group, chips convoyor,oil chiller,precise filtering system.  

Headstock: drive the workpiece rotate, rotating constant speed is 120r/min；

The main spindle will do axial movement underthe control of hydraulic system,used to loosen or fasten the workpiece.

Safety guard,the machine has two doors safety guard,will oil drip plate.  

Drill bar rest: Linkage between drill rests and drill box,no matter where is the drill bar box,the drill bar rests distance will be same.
