A new form of dry processing enables the deburring and smoothing of steel, aluminium and zinc die-cast parts. A drum with special plastic abrasives and an absorption granulate for residual grease is used here. Some materials can also be deburred part against part without abrasive bodies. With this process, both small series parts and large individual parts, can be deburred, the edges rounded and the surface homogenised. Various application examples show the wide range of possible uses for small and automated manufacturing.
