Bevel gear cutting machine for chamfering bevel gear tooth edges and method for chamfering the tooth edges of bevel gears

A bevel gear cutting machine comprising:

• a plurality of numerically-controllable axes;
• a workpiece spindle;
• a workpiece spindle axis, wherein the workpiece spindle is configured to receive a bevel gear coaxially with the workpiece spindle axis;
• and
• a deburring device including a deburring spindle configured to receive at least one first deburring tool defining at least one cutting edge;
• wherein the bevel gear cutting machine is configured to chamfer tooth edges in a first pass and a second pass;
• wherein, in the first pass, first chamfers are formed on the tooth edges by using the at least one cutting edge of the at least one first deburring tool in a continuous process in which the bevel gear and the at least one first deburring tool coupledly rotate while engaged with one another;
• and
• wherein, in the second pass, second chamfers are formed adjacent or near the first chamfers by using the at least one cutting edge of the at least one first deburring tool or by using at least one cutting edge of a second deburring tool in a continuous process, in which the bevel gear and the at least one first or second deburring tool coupledly rotate while engaged with one another.
