Title:
FREE GRINDING GRAIN INJECTION PROCESSING METHOD AND FLUID BEARING PROCESSED BY THE SAME METHOD
Document Type and Number:
Japanese Patent JPH05285835
Kind Code:
A
Abstract:
PURPOSE: To apply high-efficient refining processing, having uniform surface structure and surface nature, on a work.
CONSTITUTION: A work 2 is masked with photo-sensitive resin, a free grinding grain jet 7, wherein grinding grains 5 are uniformly dispersed in gas 6, is injected against a mask 3 at a high speed through an injection nozzle 4 to apply processing in the work 2. Simultaneously, a gas jet 9 is injected against the mask 3 at a high speed through a second injection nozzle 8 to clean and wash the work 2, and a fluid bearing is exemplified.
