Accurate plasma cutting machine cutting
In the numerical control plasma cutting machine, on the basis understanding of different power supplies, and division of cutting effects are generally divided into two:
1. Power supply of ordinary plasma arc cutter. According to the different main gases, mainly divided into radon plasma arc cutting, oxygen cutting and air plasma arc types. Cutting current cutting thickness is generally lower than current 100A for less than 30mm. Prices are very good, plasma power supply is cheap, but the groove cutting workpiece of burrs and dross to a little more, the main representative of the United States imports generally have the United States Bao ordinary machine, domestic has Sichuan Huayuan machine plasma power supply, Nantong Fuli machine plasma. But compared with domestic, imports in the accuracy of the sloped slag and burrshould be relatively much better.
2. Fine plasma arc cutting. Fine plasma arc current density is high, plasma arc is usually several times the current density, arc stability is also improved, so its cutting accuracy is very high. In China, plasma cutting manufacturing has reached the lower limit of laser cutting costs. Fine plasma machines are now much more expensive than regular plasma, but lower than laser cutters. The current fine plasma is mainly imported from the German Kelshell laser plasma power supply, the United States Flymatt fine plasma power supply, the United States fine plasma power supply, the United States Cobo fine plasma power supply.
