Waterjet cutting compared with other cutting technologies

Ultra-high pressure waterjet cutting characteristics

Any material can be arbitrary curves one-time cutting (except waterjet cutting other cutting methods will limited by the variety of materials); cutting does not produce heat and harmful substances, materials without thermal effects (cold cutting), after cutting don't need or easy to secondary processing, safety, environmental protection, low cost, high speed, high efficiency, enabling arbitrary curves cutting, convenient and flexible, and wide range of uses. Water jet cutting is the strongest applicability of cutting process. Below with the analysis of the waterjet cutting and other cutting techniques.

Comparison of waterjet cutting and laser cutting

Laser cutting equipment investment is large, now mostly used for thin steel plate, some non-metallic materials cutting, faster cutting speed, higher accuracy, but laser cutting at the slit will cause the arc tracking and cause thermal effects; also for some materials, laser cutting is not ideal, such as aluminum, copper and other nonferrous metals, alloys, especially for thick sheet metal cutting, cutting surface is not ideal, even can not cut. People present research on the high-power laser generator is trying to solve the thick steel plate cutting, but the equipment investment, maintenance and operational consumption costs is also very considerable. Waterjet cutting small investment, low operating costs, cutting a wide range of materials, high efficiency, easy operation and maintenance.

Comparison of waterjet cutting and plasma cutting

Plasma cutting has obvious thermal effects, low accuracy, the cutting surface is not easy secondary processing. Waterjet cutting belongs to cold cutting, no heat distortion, good quality of cutting surface, no need secondary processing, if need is very easy for secondary processing.

Comparison of waterjet cutting and wire cutting

Machining of metal, wire cutting has higher accuracy, but the speed is very slow, and sometimes need to use other methods for perforation, threading and then can be cut, and the cutting size is very limited, waterjet cutting can be of any material drilling, cutting, fast cutting speed, flexible processing size.
