A method in which a machining tool performs machining without directly contacting the workpiece is called non-contact machining.

Water jet machining is classified as non-contact machining as well as laser machining and wire electric discharge machining. Laser processing and wire electric discharge processing are performed by thermal energy, and water jet processing is performed by kinetic energy of ultra-high pressure and high-speed water flow. Since it is non-contact, it can be cut even with a certain shape of material.

The thermal effect, which is a weak point of laser processing and wire electric discharge processing, is extremely unlikely to occur with water jets. In addition, since the processing stress is extremely small, it is possible to maintain the material and the state as it is without damaging the material. Yes.
