Bevel gear cutting machine and method for chamfering and/or deburring tooth edges of a bevel gear

摘要

The machine (20) includes a workpiece spindle (30) for locating the coaxial mitre wheel (31) and a sleigh (18) for supporting a knife head with bar knives. The machine has at least five number controllable axes (17, 32) which can be regulated via a programmable control (29). One of these axes forms a workpiece spindle axis (32) and another forms a tool spindle axis (17) for the knife head. Adjusting at least one of the number controllable axes allows the workpiece spindle (30) and mitre wheel to be slanted relative to the knife head, so that the bar knives can be moved one after the other into gaps between the teeth in order to carry out retoothing and/or deburring work as the workpiece spindle rotates about the workpiece spindle axis at the same time the knife head rotates about the tool spindle axis.
