Le tournage est un processus d'usinage r\u00e9alis\u00e9 sur un tour o\u00f9 une pi\u00e8ce en rotation est fa\u00e7onn\u00e9e en d\u00e9pla\u00e7ant un outil de coupe le long de son axe ou radialement pour enlever de la mati\u00e8re. Ce processus permet de cr\u00e9er des surfaces cylindriques, coniques ou d'autres surfaces \u00e0 sym\u00e9trie de rotation, telles que des arbres, des trous, des filets ou des contours complexes. Le tournage est utilis\u00e9 pour r\u00e9duire le diam\u00e8tre de la pi\u00e8ce ou pour former des caract\u00e9ristiques telles que des rainures, ce qui le rend essentiel pour la fabrication de pi\u00e8ces de pr\u00e9cision telles que les arbres de transmission automobile ou les rotors de moteur, avec un mouvement d'outil et des param\u00e8tres optimis\u00e9s pour le type de mat\u00e9riau et la finition de surface souhait\u00e9e.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n
