What are the advantages of waterjet cutting comparing with plasma?
Obviously, plasma is a hot process. It adds a great deal of heat to the product, leaving a heat-affected zone. The surface finish of the abrasive waterjet is generally better. It leaves no dross on the backside of the part, reducing secondary operation. Abrasive waterjets have no thickness limitation , and can be much more closely nested. What tolerances can we expect from waterjet cutting? Over 80% of the world’s abasivejet users cut parts to ±0.003-in. or looser accuracy. However, there is a percentage of users who cut parts to tolerances as tight as ±0.001 and even ±0.0005in. The accuracy you will get depends on whether or not you have Dynamic Waterjet technology, the accuracy of the machine, part size and part thickness. Should I cut underwater? Cutting underwater will do a couple of good things for you. First, it will reduce the noise of the cutting process to under 75 dB. Second, it will eliminate the frosting of the top surface of the material within 1/16″ of the jet (it can als
