Method for machining circular magnetic steel

The invention discloses a method for machining circular magnetic steel. The method includes steps of taking a magnetic steel blank; setting machining allowance of cutting equipment and marking position marks corresponding to countersunk holes to be machined; mounting the magnetic steel blank in the cutting equipment, and cutting the magnetic steel blank to obtain cylindrical magnetic steel with position marks corresponding to the two countersunk holes to be machined; machining an inner hole of the cylindrical magnetic steel to obtain a semi-finished circular magnetic steel product; fixedly mounting the semi-finished circular magnetic steel product in a perforating fixture properly so that the two position marks are aligned with positioning marks of the perforating fixture; mounting the perforating fixture on a workbench of a drilling machine, and starting the drilling machine to drill the two countersunk holes at corresponding positions on the semi-finished circular magnetic steel product; and precisely machi
