Method and device for precision machining of toothed and hardened work wheels

A method for machining work wheels, comprising:

• providing a work wheel that has been pre-toothed with teeth having an allowance;
• hardening the work wheel to a surface hardness of at least 45 HRC, the hardening step causing a hardness distortion error that is less than the allowance;
• chucking the work wheel on a workpiece spindle;
• gear skiving the work wheel using a skiving wheel to remove at least 50% of the allowance therefrom, the gear skiving involving rotationally driving the skiving wheel with a tool spindle;
• during the gear skiving step, moving the skiving wheel in a direction of an axis of the work wheel, wherein the moving step involves no movement in a radial direction perpendicular to the axis of the work wheel;
• without rechucking the work wheel after the gear skiving step, precision machining the work wheel using a honing wheel, the precision machining involving rotationally driving the honing wheel with the same tool spindle that rotationally drives the skiving wheel;
• and
• during the precision machining step, moving the work wheel in an oscillating motion in the radial direction perpendicular to the axis of the work wheel.
