A machine for reproducing an article from a pattern, wherein the pattern and the article are mounted respectively on parallel supporting shafts and driven at the same speed of rotation, and are in contact with a feeler and a tool, respectively. The two shafts are mounted on a table designed to make two perpendicular movements, namely an advance movement in a direction perpendicular to the supporting shafts and a contact movement in a direction parallel to those shafts. The invention is applicable in particular to the roughing out of toric lenses.
