Method and device for deburring a workpiece with an inner toothing

A method for deburring an internally toothed workpiece, comprising:

• providing a workpiece having:
• an axis of symmetry;
• and
• an inner toothing produced by hob peeling, the inner toothing comprising first tooth flanks and second tooth flanks;
• providing a deburring tool having:
• a center axis;
• a first cutting plate;
• and
• a second cutting plate, diametrically opposed to the first cutting plate with respect to the center axis;
• aligning the center axis to be parallel to the axis of symmetry;
• rotating the workpiece in a first rotating direction;
• deburring the first tooth flanks with the first cutting plate while the deburring tool is not rotating;
• keeping the center axis parallel to the axis of symmetry and shifting the deburring tool relative to the workpiece such that the first cutting plate and the second cutting plate do not contact the workpiece;
• rotating the workpiece in a second rotating direction, opposite the first rotating direction;
• keeping the center axis parallel to the axis of symmetry and further shifting the deburring tool relative to the workpiece;
• and
• deburring the second tooth flanks with the second cutting plate while the deburring tool is not rotating.
