Process for inserting points in a mandrel |
摘要 |
A process for inserting points (38) on a mandrel (36) and a machine for performing this process. A working head (40) simultaneously ensures the insertion of a point and the making of a perforation (112) in the mandrel by means of a punch (94). The perforation is made in the same longitudinal row as the inserted point and towards the front with respect to the latter, in such a way that it is subsequently possible to guide a point following a rotation of one or more turns of the mandrel. The invention is applicable to the production of members or bodies of revolution made from three-dimensional material.
