Ive heard of water-only waterjet cutting. What is it and why would I choose that over abrasive waterjet cutting?
The most obvious difference between the two is the lack of abrasive in pure waterjet cutting. Since abrasive waterjet is more commonly used on hard and thick materials, water-only is often used for processing materials such as; PTFE, plastics, neoprene rubber, foam board, composites, cellular silicone, nylon reinforced rubber, and virtually any flexible material. Water-only processing has no heat affected zones, as to not alter any of the materials being processed. Water-only waterjet generates a fine jet of water with very high energy. Water-only cutting is a non-contact process which means there is minimal lateral effect on the part. It can also be used to process materials ranging from .004″ to .010″ in diameter. Another reason why you might choose water-only processing is for its cleaner processing. When abrasives stream through soft, light-colored materials, they often leave a dirty trail behind them. However in water-only cutting, there are no abrasives, thus no trail and the res
