Abstract
A lapping device for surface enhancement of bulk material including a treatment chamber which is closed gas-tight and is charged with an inert gas, at least one vibratory conveyor being arranged in the treatment chamber and an arrangement for creating motion between a lapping abrasive liquid and the goods on the conveyor to form a surface enhancement for the goods. The arrangement for creating motion can be either abrasive nozzles for creating a jet of abrasive material directed onto the goods, the movement of the vibratory conveyor through a bath of the lapping abrasive or a combination of both. The lapping device is particularly useful for pretreatment of bulk goods which are to be electro-plated.
