1. Applicable for automatically drilling and marking heavy-duty angle bars.

2.  Advanced main machine body’s structure, the drilling spindle works at the direction from top to bottom, different from the traditional work direction from bottom to top, it can effectively avoid the damage to the spindle caused by cooling water and scrapes, this advance structure can greatly enhance the spindle’s life span.

3. The machine adopts simple automatic tool changing system. There are 3 drilling tools standby at each side, it can meet the demand of drilling multiple hole diameters. It reduces both the spindle numbers and the manufacture cost, and the machine’s automatic production efficiency is very high.


4. It consists of six major components, including in-feeder conveyor, main machine body, finished angle bar out-feeder conveyor, hydraulic system, and electrical control system.

5. It's high speed drilling machine for heavy duty angle bars, with very high production efficiency and capacity.
