Drilling Machine of Ring-Die

  • Brand Name:CWT

Item Name:Drilling Machine of Ring-Die 


[Mechanic Brief Description]

This is a full-automatic intelligent drilling machine for ring-die and roller assembly which has such advantages as Low investment costHigh EfficiencyGood Countersinking QualityStable Function etc; The electric control system consists of high sensitive digital-control system with variable frequency control & serve motor. The motion system consists of screw rod & rail with high precision.


Equipment’s Features:

·         High-Automation, Easy hole-machining operation;

·         Low consumption on electricity;

·         Low production cost (One labor can run over 10 such drilling machines).

Equipment’s Function:

1、              This drilling machine is suitable for holes’ machining operations such as drilling, countersinking & counterboring on torus. The depth of hole can be adjusted at random.

2、              If the depth of the pressure-relief vent at both ends of the ring-die are different, the depth can be set in this system in advance then this drilling machine can operate to this depth automatically

3、              The number of holes can be set at random but holes will evenly distribute on the circle of the ring-die’s surface. Those holes on the odd row and the even row will automatically mismatch.

4、              The wear detection on main-axis torque and alarm limitation can be set at will, the wear on drill head can be monitored at any time thus it can effectively prevent drill-head breaking unexpectedly.

5、              During drilling machine operates, the falling speed / rotate speed  of drill chuck and indexing speed of universal indexing head can be adjusted at will.

6、              The falling depth of drill chuck can be set at will; the semi-finished holes can be conveniently improved by hand.

7、              With the alarm detection function, the machine greatly shortens invalid operation time when the drill-head is broken.

8、              Pause / Start at any time, unnecessarily point to the hole.

9、              Memory function when power –off.

10、           Convenient Operation
