Technical characteristics:

(1) Function of hydraulic power stations:to clamp and unloose the workpiece, and maintain an adequate lamping force in the process of drilling. drive the main shaft of drilling press to feed, and achive fast close the workpiece,the slow work feed and fast return. the close orientation after movement of the machine can improve the accuracy of the location of drilling and dimension of workpiece.

(2) It adopts technologythe principle of self-controlled stroke of drilling: there is no need to use pre-set parameters. The transfer of automatically fast feedslow feed of workpiecefast return is completed through joint function of machine,electricity and liquid.There is no empty stroke consumption, easy to operate and is high effcient.

Characteristics:

A. Exchangeable double-tables;

B. Four sets of workpiece can be clamped simultaneously;

C. 12 rapid hydraulic clamps around the table

D. Self-controlled stroke drilling head;

E. Automatic chip removal;

F. CNC & PLC system, CTR display;

G. Max. diameter of drilling (mm):Φ50;

H. Max. size of workpiece (mm):3000*3000*300

I. Ideal drilling machine for joint plates.
