  • Method for soft machining of bevel gears
    Patent number: 7574798
    Abstract: A device (10) for soft machining of bevel gears, having a receptacle (12) for receiving a bevel gear blank (K1) and having a tool spindle (13.1) for receiving a cutter head (13.2). The device comprises a machining arm (11) having a pivot axis (A1) which has the tool spindle (13.1) for receiving the cutter head (13.2) on a first side and has a tool spindle (14.1) for receiving an end-milling cutter (14.2) on a second side. A CNC controller (S) puts the end-milling cutter (14.2) into rapid rotation to cut a predefined number of tooth gaps on the bevel gear blank (K1). After the machining arm (11) is pivoted, the cutter head used as the bevel gear finishing tool (13.2) is used. It is put into slower rotation to machining the bevel gear blank (K1) using the bevel gear finishing tool (13.2) in a post-machining process.

  • DEVICE AND METHOD FOR SOFT MACHINING OF BEVEL GEARS AND USE OF THE DEVICE
    Publication number: 20070283545
    Abstract: A device (10) for soft machining of bevel gears, having a receptacle (12) for receiving a bevel gear blank (KI) and having a tool spindle (13.1) for receiving a cutter head (13.2). The device comprises a machining arm (11) having a pivot axis (Al) which has the tool spindle (13.1) for receiving the cutter head (13.2) on a first side and has a tool spindle (14.1) for receiving an end-milling cutter (14.2) on a second side. A CNC controller (S) puts the end-milling cutter (14.2) into rapid rotation to cut a predefined number of tooth gaps on the bevel gear blank (K1).
