SUPERNOVA CNC plate drilling machine has subverted the traditional processing mode for hole processing in chemical industry. It is now the main CNC drilling machine for processing chemical flange, heat exchanger, tubesheet, etc. Before using the traditional hole processing method, first fitter scribed positioning, and then fixed the well positioned tubesheet on the bench vice, and then drilled with a radial drilling machine. For large hole diameter, even through two procedures of drilling and reaming. Compared with the traditional hole processing method, the advantages of NC plate drilling machine are as follows:

（3） In terms of machining accuracy, there are many uncertainties in the processing of artificial holes, which makes it difficult to assemble due to large errors. If the errors are too large, the workpieces will be scrapped and bring losses to enterprises. While the plate drilling machine adopts CNC positioning and precise processing, the positioning accuracy of the hole can reach ± 0.08mm, which can meet the processing requirements.
