SRA166H

Nearly 20 years ago, Nachi was the pioneer of servo gun technology for spot welding.  Today, Nachi continues to lead the industry in development of advanced robotic spot welding solutions focused on making higher quality welds more quickly than in the past.  Specifically designed for the fast paced automotive industry, SRA series robots will dramatically reduce cycle times, significantly improve productivity, and achieve cost reductions…achieve more with less robots! In your business “Time is Money”, make the most of your money with the fastest robots available. Compare the Nachi SRA series against any competitor to see how much valuable time and money you can save with an SRA robot.

SRA series robots and their FD controllers are ideally suited to spot welding applications.  The SRA robots are highly rigid and weight less, providing faster motion and less vibration.  Advanced motion control from the FD controller provides top acceleration thereby shortening cycle-times.  The FD also has 4th generation servo gun control software enabling higher motor speeds while maintaining gentle electrode contact to parts, optimizing spot welding performance.  Finally, Nachi together with our welding partners, Obara and Art Hikari, are pushing the envelope in resistance welding with lightweight modular guns and spot-welding solutions for aluminum parts.

Description

Improved reliability for welding cables and hoses

  • The reliability is improved by stabilizing cable performance to avoid damage due to interference with peripheral equipment.

Shortened the startup time

  • We greatly decreased the time to check work programs because cables do not interfere with peripheral equipment.

Expanded the operating range of the wrist

  • Compared to the existing A-Trac, we expanded the operating range of J5 ±10° and J6 ±5° (payload class 210kg), increasing the range of linear movement 20%.

Improved accessibility

  • When compared to the existing A-Trac, we have decreased the interference range of the wrist 27%, making access to narrow places possible.

Speed

  • The hollow arm can also operate at the same high speeds as the SRA.
