3FG15 Three-finger Gripper
The 3FG15 is ideal for gripping a wide range of cylindrical objects in machine-tending applications such as CNC lathe machines. The gripper’s design automatically centers workpieces, resulting in fast deployment with a strong, stable grip and precise placement. With a payload of up to 15kg, the 3FG15 competes with larger, bulkier, and much less flexible finger grippers. Like all OnRobot grippers, the 3FG15 offers seamless integration with the robots of your choice.
