SUPERNOVA CNC plate drilling machine has subverted the traditional processing mode for the hole processing in the chemical industry. It is now the main CNC drilling machine for the processing of chemical flange, heat exchanger, tube sheet, etc. Before using the traditional hole processing method, the fitter first marked out and positioned, and then fixed the positioned tube plate on the vise, and used the radial drilling machine to drill holes. For large hole diameter, it even had to go through two procedures of drilling and reaming. Compared with the traditional hole processing method, the advantages of using CNC plane drilling machine are as follows:

1） The step of manual scribing is omitted in NC plane drilling machine. The traditional way of hole processing and positioning is mainly that the technical workers mark and position the designated position according to the requirements of the drawing, and use the hand electric drill or magnetic drill to drill the positioning hole, which has large error and low efficiency. When drilling on the NC plane drilling machine, it is only necessary to input the parameters such as the position and number of holes into the computer, or input the correct CAD design drawing, and use the photoelectric edge finder device to find any three points on the processing workpiece, so as to realize the automatic and continuous processing of large hole diameter of the drilling power head. The operation is very convenient, the accuracy is high and stable.
