1. It is composed of main machine (3D drilling machine), hydraulic system, conveying material channel and electric control system. It is mainly used for secondary processing of steel structure and H-beam drilling on three sides.
2. CNC three-dimensional drilling is composed of main engine, hydraulic system, conveying material channel and electrical control system.
3. The drill press has three power heads, and the holes on the three faces can be processed when the workpiece passes.
4. Three power heads can be drilled at the same time, and the power head is drilled by self-controlled stroke.
5. It is not necessary to set the thickness of the workpiece and the length of the drill bit, and automatically carry out fast forward and work forward conversion, and the processing efficiency is high.
