Patent number: 9114503Abstract: A nozzle, a nozzle unit having a plurality of nozzles, and a blasting machine equipped with the nozzle unit, which can achieve a micro-machining with a high precision and a high productivity for the blasting process. A portion for escape 13c is formed at the distal end of the ejecting portion 13 of the nozzle 11, so if the distance between the surface of the work and the nozzle 11 is shortened to suppress the broadening of the flow of the abrasives, the reflected abrasives do not remain within the space between the surface of the work and the distal end of the ejecting portion 13. Thus, a blasting process with a high precision can be achieved. Further, since two nozzles 11m and 11n can be arranged so as to correspond to the width of the surface of the work to be processed by a rotational device 16, it is possible to blast a wider area of the surface of the work while the nozzle unit 10 or the blasting machine 20 sweep one time. Thus, the high productivity of the blasting process can be achieved.Type: GrantFiled: April 10, 2009Date of Patent: August 25, 2015Assignee: 1.
