Abstract: A method and apparatus for adapting a turret extender to Computer Numeric Controlled (CNC) lathes, equipped with a main turret which is indexable about an indexing axis is disclosed. The disclosed turret extender mounts directly to the Original Equipment Manufacturer's (OEM) turret to extend the maximum turning diameter of the lathe by augmenting the original tool mounting configuration. The turret extender can accommodate, individually or in combination one or more standard tools, one or more modular tools and one or more relocated tools either standard or modular. By attaching to an OEM turret, the turret extender utilizes the original indexing electronics and hydraulics of the OEM main turret. The turret extender therefore provides enhanced machining capability in a cost efficient manner.
