while the robotic arm’s gripping jaws use an internal supporting method to grasp the workpiece.

In an automated lathe system, the internal expansion clamping jaws (inner expanding grippers) play a crucial role in securely positioning and stabilizing workpieces during machining. These jaws expand from the inside of the workpiece to achieve precise and firm clamping, ensuring that the part remains stable even under high cutting forces. Some clamping jaws use a direct metal-to-metal contact structure, providing strong rigidity and high accuracy for hard materials or precision turning. Others are equipped with rubber pads on the expansion surface to offer a more flexible grip, effectively preventing surface damage and improving the adaptability for thin-walled or delicate parts.
