<p>A radially inwardly open raceway formed in a nut centered on a nut axis is machined by of oscillating the nut about the nut axis while pressing a tool secured in a holder radially outwardly into the raceway of the nut. The holder is moved parallel to the nut axis and oscillated about a tool axis perpendicular to the nut axis synchronously with the oscillation of the nut about the nut axis. Springs brace the tool against the holder parallel to the nut axis such that the tool can move limitedly in the holder against spring bias parallel to the tool axis.</p> |
