Deburring unit for edge of limited access bore - has conical milling cutter at side of extension arm driven via belt and gearing

摘要

The de-burring tool is intended for cleaning up the edge of a bore, particularly where this edge is not easily accessible e.g. between the legs of a U-shaped fork. It comprises a drive e.g. a flexible shaft, with a gear transmission (1) in a housing (9) carrying a fixed or interchangeable arm (3), at the end of which a pulley (5) carries an interchangeable conical milling cutter (6). The cutter is coupled to the transmission via toothed belt or the cutter may be driven via intermediate gear wheels. The cutter may be a cone or a shallow truncated cone, for use inside a narrow fork opening.
