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:

（5） In terms of efficiency, traditional hole processing requires a worker to draw lines, a worker to drill holes, a worker to punch and locate, a worker to load and unload, and a worker to drill holes. The CNC plate drilling machine only needs one technician and one loader. Save two labor costs. The traditional processing method takes about 3.0 hours to process a tubesheet, while the CNC plate drilling machine only takes 0.5 hours, which improves the efficiency by about 6 times. So it can be seen that the processing method of NC plate drilling can not only save the cost, but also improve the production efficiency and bring economic benefits to the enterprise owners.
