The three-dimensional drill is mainly used for three-dimensional drilling processing of large-size H-beam or box girder. It adopts the method of workpiece fixed gantry moving. It has the characteristics of high processing efficiency and stable precision, and can be widely used in construction, bridge, iron tower and other industries. < br style = "list style type: none;" / > product advantages: < br style = "list style type: none;" / > 1. Adopting the way of fixed gantry moving, it has high processing efficiency and stable precision. < br style = "list style type: none;" / > 2. It can realize the direct conversion of CAD / CAM, thus eliminating the tedious operation of programming and input. Automatic generation of processing procedures, to achieve paperless processing equipment. The ball screw pair, linear guide pair, electrical parts, servo motor, frequency converter, etc. of the machine tool are supplied by well-known manufacturers at home and abroad, with few startup faults. Although the 3D drill is expensive, it can save scribing time, reduce adjustment, processing and inspection time, and save direct production cost; the processing precision is stable, and the three-dimensional drill can realize multi-purpose, save plant area and investment. Therefore, good economic benefits can still be obtained by using 3D drill.
