Apparatus for finishing articles, particularly the ends of fibre optic cables, with a convex surface, comprises a lapping wheel (61) rotatable about a vertical axis and having a concave cavity (90) with a radius of curvature corresponding to the desired radius of curvature for the surface of finished articles. A carriage (30) holds the articles against the surface of the cavity and is mounted with a ball bearing (75) for universal swivelling movement. The centre axis of the cavity (90) is offset from the axis of rotation of the lapping wheel so that as the wheel rotates and the cavity moves around the axis of the rotation of the lapping wheel the carriage is caused to rock and the articles move over the surface of the cavity. |
