Double Spindle CNC Gun Drilling Machine

1.Overview of Machine Tools

Drilling range：Φ3～Φ20mm

Maximum drilling depth：500 mm

Maximum borehole length-to-diameter ratio 100:1

Range of workpiece outer diameter：Φ15～Φ100mm

 

1.1 The gun drill drilling method, with a dual spindle structure, can process two workpieces simultaneously, and is suitable for the processing of coaxial holes on shaft-type parts;

 

1.2 During the processing, the tool and the workpiece rotate relative to each other, and the tool moves in. This is used for the processing of concentric holes in shaft-type parts.

 

1.3 Workpiece clamping: The front end of the spindle of the headstock and the guide frame are equipped with a conical disk. The hydraulic system controls the axial movement of the headstock spindle. By using the conical disk and the chamfers at both ends of the workpiece, the workpiece is automatically clamped and positioned.

 

1.4 The guide rails used on the machine tools are of linear type.

 

1.5 Control system：GSK

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.6 Drill Rod Box: It is driven by a servo main motor through a synchronous belt and synchronous pulley to rotate the main shaft. This enables stepless speed adjustment. The maximum rotational speed of the main shaft is 5000 r/min. There are two main shafts: one motor drives both main shafts to rotate. The main shafts are driven in front, which is beneficial for protecting the main motor and facilitating tool change.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.7 Headstock: It drives the workpiece to rotate at a constant speed of 117 r/min. The main shaft can move axially under the control of the hydraulic system and is used for clamping or loosening the workpiece. The main shaft is driven in front, which is convenient for loading and unloading the workpiece and beneficial for protecting the main motor.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.8 Tool Feed System: It adopts a structure of servo motor driving a ball screw. The feed amount of the tool can be adjusted steplessly.

 

1.9 Drill Rod Support: The drill rod support and the drill rod box can be linked. The distance between the drill rod supports is equal at any position of the drill rod box.
