scheibenfoermiges, rotating tool for moulding cylindrical schleifschnecken for grinding zahnraedern.

摘要

The tool consists of two discs (46, 47) and has two hard-grain-coated surfaces (48, 49) for shaping the opposite flanks (3, 4) of the grinding worm (1). The hard-grain-coated part (50, 52) provided for shaping the base and head sections (5, 6) directly adjoining the one flank (3) machined by the one disc (47) is in each case arranged on what is respectively the other disc (46). Consequently, the surfaces (48, 49) can be lapped. A grinding worm (1) can be shaped by the tool in one pass. Consequently, the shaping can be easily automated. …IMAGE…
