About

About 3FG25 Finger Gripper

OnRobot 3FG25 is a three-finger electric gripper for CNC machine tending, material handling and assembly with larger workpieces. Its fingers move concentrically to centre cylindrical and irregular parts for placement in machine chucks or fixtures. The gripper supports workpieces up to 25 kg, a 155 mm maximum stroke and up to 450 N of gripping force.

The IP67 enclosure is intended for machining environments exposed to coolant and chips. Grip position and force are configurable for part changes, and OnRobot supplies hardware and software interfaces for major collaborative and industrial robot brands. The product is commercially offered as a complete end-of-arm tool.
