ABSTRACT:
Method and apparatus for collecting dust and shavings produced by a drum and disc lathe. The apparatus comprises a sealed housing which is adapted to enclose the entire grinding or cutting area of the lathe and trap airborne particles suspended therein. A brake drum or disc is attached to the lathe arbor within the housing through a housing access door prior to the machining operation. The cutting tool extends from the lathe into the housing through an orifice which is covered by a plurality of sealing strips. As the drum or disc is machined, the suspended asbestos and metal dust is removed from the housing to a collection receptacle by the directional air flow from a fan and the heavier metal shavings are collected in a tray located on the housing floor.
