Dry blasting process for applying to groove shapes involves creating roughness by dry blasting with granular material

摘要

The dry blasting process produces a groove shape with a radial recess for a sealing ring. The groove has a cylindrical surface intended to act as a resting surface for the sealing ring. Roughness is applied to the required part of the object (1) by means of dry blasting with abrasive grains, using a material with a specific gravity higher than that of quartz.
