Collaborative Gripper Boosts Profitability and Reduces Misloads by 40%

POSTED 09/17/2020

RG6 gripper offers flexible, precise gripping for different sizes and shapes and multiple processesTomenson Machine Works in Chicago wanted to automate its pin-stamping application to improve quality, profitability, and worker satisfaction. The third-generation, family-owned manufacturer of precision hydraulic manifolds deployed the RG6 gripper to handle a wide array of part sizes, increasing quality and profitability.


  • <1 day gripper implementation
  • <1 week automation cell implementation
  • 20-30 different parts
  • 40% reduction in misloads
  • 5-10 minute change-over time
  • 10-15 minutes programming for new part
  • ROI in 6-7 months over two shifts

“OnRobot’s grippers are a game-changer because whereas we were normally seeing one gripper, one part, we now see the flexibility that the OnRobot grippers offer customers.  A lot of our customers traditionally were using a single gripper—maybe a two-jaw gripper or a three-jaw gripper for one part—but now we’re seeing that the RG6 can do multiple parts for multiple jobs.” Brian Einzig, automation specialist, FPE Automation

Before this system and the gripper, we definitely had lower profit margins on these small blocks. Now when we see a small block, we’re not afraid to quote it because we know handling thousands and thousands of these will be done by the robot, not a human, which makes us less fearful of quoting very high-volume and little parts.”  Alex Roake, Tomenson operations manager 

Ease of Use
“Now that we have one successful application with the OnRobot RG6 gripper we have looked into other possibilities in post-production or shipping or even loading up the CNC machines. The ease of programming is what leads us to be confident in this decision that we can take it to other departments, because we don’t need to hire an extra programmer.” Alex Roake, Tomenson operations manager.
