Deburring machine and method for deburring

A method for deburring a ground metal part, the method comprising:

• loading a ground metal part into a circular opening in a carrier of a deburring machine;
• moving the carrier along a rail of the deburring machine so as to align the circular opening of the carrier with an opening in a frame plate of the deburring machine;
• contacting a first planar surface of the ground metal part with a first grinding wheel;
• extending a second grinding wheel through the opening in the frame plate so as to contact a second planar surface of the ground metal part, wherein the second planar surface is opposite to and parallel with the first planar surface;
• with the first grinding wheel in contact with the first planar surface, rotating the first grinding wheel in a first rotational direction about a first rotational axis, which is parallel to and offset from a central axis of the circular opening in the carrier;
• with the second grinding wheel in contact with the second planar surface, rotating the second grinding wheel in the first rotational direction about a second rotational axis, which is parallel to and offset from the central axis;
• with the first grinding wheel in contact with the first planar surface, rotating the first grinding wheel in a second rotational direction, which is opposite to the first rotational direction, about the first rotational axis;
• and
• with the second grinding wheel in contact with the second planar surface, rotating the second grinding wheel in the second rotational direction about the second rotational axis.
