Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a tooling structure for a CNC spinning machine. [Background Technology]
[0002] Existing spinning machines typically fix the metal parts, such as metal lamp holders, to the rotating end before pushing the corresponding cutting tool to engage with the metal part to achieve cutting and grinding functions. However, existing tooling fixtures are all single-structure, allowing only one tool to be installed at a time, necessitating frequent tool changes and impacting production efficiency. Therefore, we have improved the tooling fixtures for CNC spinning machines to avoid frequent tool changes during production. [Utility Model Content]
