AWR Standardizes CNC Machine Tending with OnRobot Electric Grippers to Speed Changeovers

Why It Matters

By moving to intelligent electric grippers, AWR cuts changeover time and maintenance costs, giving high‑mix, low‑volume producers a scalable automation solution that directly enhances profitability.

Key Takeaways

• AWR replaced six pneumatic grippers with OnRobot 3FG25 electric gripper.
• 3FG25 handles up to 25 kg payload with programmable force and stroke.
• Dual‑gripper setup cuts cycle time by picking and loading in one pass.
• No mechanical adjustments needed when switching part sizes, reducing downtime.
• Electric gripper eliminates air lines, lowering maintenance and part count.

Pulse Analysis

High‑mix, low‑volume manufacturing has long wrestled with the rigidity of pneumatic end‑of‑arm tools. Traditional grippers deliver an all‑or‑nothing grip, require custom fingers, and depend on compressed air, leading to frequent pressure loss and costly changeovers whenever part dimensions shift. AWR’s decision to adopt OnRobot’s 3FG25 electric gripper reflects a broader industry push toward smarter, more adaptable automation that can respond to frequent product variations without extensive re‑engineering.

The 3FG25’s technical specs—25 kg payload, 137 mm adjustable stroke, and force control ranging from 50 to 450 N—provide the precision needed for delicate workpieces while maintaining the strength for heavier components. Integrated force monitoring and position feedback enable the robot to automatically center and secure parts, eliminating manual calibration. AWR’s dual‑gripper layout further streamlines operations by completing pick‑and‑place cycles in a single motion, effectively halving cycle time and improving equipment utilization, which translates into a measurable boost in return on investment for its customers.

AWR’s rollout signals a growing acceptance of electric grippers across the CNC automation market. By removing air lines and solenoids, manufacturers can simplify cell design, reduce part counts, and lower maintenance overhead. The move also positions OnRobot as a key supplier in the evolving ecosystem of intelligent robotics, where data‑driven grip control and rapid re‑programming are becoming standard expectations. As more shops adopt similar solutions, the competitive landscape will favor firms that can deliver flexible, high‑precision automation without sacrificing uptime or cost efficiency.
