When selecting equipment for gantry machining centers, basic requirements should be placed on the fixtures. The clamping mechanism should not affect the feed, the machining parts should be open, and the fixtures can be installed in a directional manner on the machine tool. The rigidity and solidity of the fixtures should be good.

Universal fixtures such as vice, indexing head, chuck, etc. Combination fixtures are composed of a set of standardized and dimensionally standardized universal component combination components. They are designed and manufactured specifically for a certain or similar processing. Multi station fixtures can be used to clamp multiple workpieces at the same time. Group fixtures are specifically designed for positioning and clamping with similar shapes and sizes Clamping of workpieces with the same or similar processing methods. The principle of selecting fixtures for gantry machining centers is to prioritize the use of universal fixtures while ensuring machining accuracy and production efficiency.
