Method for producing a spindle nut for a ball screw

A method for producing a spindle nut for a ball screw, the spindle nut having a ball groove for balls incorporated at an inner periphery of the spindle nut, the ball groove extending over at least one thread and extending around a rotational axis of the spindle nut along a helical line, the method comprising:

• using a single tool to form the ball groove and a ball inlet;
• moving the tool radially outwardly in order to remove more material from the spindle nut to form the ball inlet, the moving step beginning at a first point of the ball groove and ending at a second point of the ball groove, the locations of the first and second points each depending on a relative rotary progress of the tool in reference to the spindle nut;
• reversing the radially outward movement of the tool, and further processing of the ball groove, wherein the moving step and/or the reversing the radially outward movement step form the ball inlet;
• and
• forming an opening that extends to the ball inlet, the opening being located at an outer periphery of the spindle nut between the first and second points.
