SHOT-BLASTING MACHINE BASED ON BOTH RADIAL IMPELLER METHOD AND AIRBLASTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method which achieves a uniform shot-blasting effect on an object or a product material having a large surface area and a complicated shape.;SOLUTION: According to the method, the product material which is installed in a batch-type jig, is subjected to projection by radial impellers (3, 4) having respective wide projection angles (7, 8), and local areas of the product material, falling out of projection ranges, are then subjected to projection of a projection material based on an air nozzle blasting method exhibiting high local projection effects (9, 10). Herein both the radial impellers and air nozzles are set and combined with each other in the same cabinet that can compensate for weak points of the radial impellers and the air nozzles, and therefore the product material can be uniformly treated and mass processing of product material can be realized simultaneously.;COPYRIGHT: (C)2006,JPO&NCIPI
