  • Patent number: 9114503
    Abstract: 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.

  • Patent number: 8814634
    Abstract: This invention provides a conveying apparatus and a blasting machine equipped with the conveying apparatus that can prevent workpieces from being damaged by the used abrasives attached to the conveying rollers. For the conveying apparatus, a peripheral part 33a disposed at the peripheral surface of a rolling member 33 of a rolling roller 31 is made of a softer elastic material than the material of the panel P, wherein when used abrasives get stuck between the peripheral part 33a of the rolling member 33 and the panel P, since the peripheral part 33a acts as a cushioning material that can reduce the force caused by the used abrasives and loaded on the panel P, even if the panel P is made of a fragile material, such as glass, the panel P can be conveyed without flaws being caused by the used abrasives.
