1) Drill hole method: Gun drilling method. The machine is used for processing concentric hole on cylindrical workpieces. Both workpiece and cutter can rotate.

2) When boring, adopts front chips removal method. It means the chips will flow out from headstock front end.

3) Workpieces load and unload adopts two-ends cone disc automatic tighten method, both ends of workpiece are chamfered.

4) The user should provide the chamfer size of workpiece both ends and workpiece size when ordering the machine.

5) The machine adopts linear guide rail.

6) The machine equips with full safety guard with six doors and oil mist collector.

7) Cutter spindle is driven by servo main motor and Synchronous belt, stepless speed adjustment can be realized. Main motor power is 7kw, spindle rotary speed range is 500~6000r/min.

8) Cutter infeed movement adopts structure of servo motor, spring coupling and ball screw, speed stepless.

9) The machine equips with 10 pieces of dill bar support rest, the distance between drill bar support rest will keep the same under any conditions. Length of 10 pieces drill bar support rest getting together is 360mm. Length of guide frame is 160mm.

10) Guide frame of drill head can do axial movement for 50mm driven by hydraulic cylinder.

11) Guide rail used for workpiece tighten, loosen and movement is linear guide rail.

12) Adopts four sets center frame to support the workpiece. Suitable for workpieces with outer diameter range Φ10~Φ40mm; Center frame upper cover adopts cylinder automatic open and close.

13) Headstock drives the workpiece to turn, adopts servo main motor and synchronous belt to drive the spindle to rotate, speed stepless can be realized. Spindle front end adopts cone disc and chuck head body structure.

14) Machine coolant system include chain plate chips conveyor, magnetic roller filter, paper filter, oil temperature controller, high pressure frequency conversion pump groups and liquid level controller. The cutting oil pressure and flow can be adjusted according to hole diameters, and the value of flow and pressure can be shown also.
