The automotive/standard chuck features a modular design, making it easy to replace parts, and expand clamping sizes and positioning methods. It allows for interchangeable components such as arms, jaws, central positioning mechanisms, and locating pads, which can be customized to meet different requirements. The chuck body is engineered with multiple weight-relief areas to reduce the load on the machine interface. The main structure is highly rigid, durable, long-lasting, and has low consumable requirements.
