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.
Flexible production - large-stroke optimizes CNC lathe-tending for multiple part sizes with a single 3-finger gripper
Accurate centric positioning drives higher quality, consistency, and output with minimal programming
Strong, stable grip with 3 contact points makes gripper fast and easy to redeploy for multiple processes
Accomplish more with customizable fingertips to flexibly grip a wide range of part sizes and shapes
Why 3FG15 three-finger gripper?
One tool fitting your CNC lathe tending needs – high flexibility
Handle multiple part sizes with large stroke gripping
Faster, more productive solution
Fast and easy to redeploy for multiple processes, high productivity
Simplified one software system
Easy deployment, minimizes number of engineering hours
