Jet finishing machine, jet finishing system using two-phase jet finishing method

摘要

A jet finishing machine comprises: a water nozzle (1) for spouting a water jet flow of water in a liquid phase; a steam nozzle (3) for increasing the speed of a steam flow (4) in a gas phase to an ultrasonic speed to produce a steam jet flow (11) and for spouting the steam jet flow in excess of a thermal equilibrium with the water jet flow; and a mixing nozzle (2) for mixing the steam jet flow with the water jet flow so as to allow the steam jet flow to accelerate the water jet flow to form a two-phase jet flow (12) of the water jet flow and the steam jet flow and for directly spouting the two-phase jet flow onto a work piece (5).
