Method for aqua-blasting component surfaces

摘要

The machine comprises a conveyor (3) for the components (6) with a liquid-gas sprayer (10) contained in the conveyor, and a water-sprayer (11), behind which is a bead blaster The components are coated with a layer of water before undergoing blasting and are cooled down to freezing temperature at least on their surface. The components are sprayed with liquid gas and then with water, before undergoing bead blasting. The components have cavities (9) opening towards their surface and closed with ice before blasting.
