Description

Turning and milling composite turret tool rest Technical Field The utility model belongs to the technical field of numerical control machine tools, and particularly relates to a turning and milling composite turret tool rest. Background The turning and milling composite turret tool rest is one of core components of a modern numerical control machine tool, and originates from the improvement of high-efficiency and precise machining requirements of the manufacturing industry at the end of the 20 th century, along with the increase of integrated machining requirements of complex parts in the fields of aerospace, automobiles and the like, the traditional single-function turret tool rest can not meet the requirement of multi-station integration, the development of a turret tool rest with turning and milling functions is promoted, the turret tool rest realizes the seamless switching of a turning and milling process through a high-rigidity turret structure, a multi-station automatic tool changing system and CNC precise control, the clamping times and the auxiliary time are greatly reduced, and the turret tool rest is an important technical extension of a five-axis linkage machining center.
