ABSTRACT:
A method and apparatus for collecting dust and particles produced in machining a workpiece. The method and apparatus uses a shroud formed by a pair of frusta-conical walls spaced apart from each other to define an annular air passage therebetween. The shroud is mounted so that the machine tool extends through a central opening formed in the shroud. The annular air passage has an upper air inlet intersecting the air passage with a cylindrical component and a lower air outlet facing inwardly toward the machine tool. Pressurized air flows into the air passage and is thus directed from the air outlet toward the machine tool in a swirling manner. At the same time, a vacuum withdraws air from within the shroud to collect dust and chips produced by the machine tool.
