The invention discloses a superfine process for the outer
diameter of a spherical roller. The superfine process comprises the following specific steps of: 1, debugging according to the size of a workpiece and selecting
machine tool fittings of different specifications; 2, switching on a general power supply of a
machine tool and a cooling pump and selecting a working status; 3, adjusting the
machine tool and setting parameters thereof; 4, feeding with a blanking cylinder of a feeding / blanking mechanism; 5, driving the roller to rotate with a workpiece transmission mechanism, making an oscillating mechanism oscillate and making a superfine mechanism jump into a
processing position; 6, performing rough
processing and superfine
processing with the superfine mechanism; 7, stopping the superfine mechanism, the oscillating mechanism and the workpiece transmission mechanism; and 8, blanking with the feeding / blanking mechanism. The invention has the advantages: the spherical roller has a long service life; the roughness value is small, the Ra is 0.05 mum after superfine processing, the circular degree is increased by 30 percent and is less than 1 mum, and the corrugation is reduced by 30 percent and is less than 1 mum; and the spherical roller is arranged on an
elevator bearing after superfine processing, so that the
noise is lowered by 30 percent and meets the user requirement in comparison to the
noise before superfine processing.
