Two variants join family: now with payloads from 155 to 200 kilograms and reaches from 2.85 to 2.60 meters
Robust yet precise: Collision resistant with moment of inertia capabilities and highly accurate next generation motors
Built around Lean ID: Cost effective Integrated Dressing (ID) for easy programming, reduced wear and small footprints
Simplified maintenance: Longer service intervals, highly accessible components and optimized service routines
Lowest Total Cost of Ownership: Key improvements combined with better energy efficiency add up to a 20 percent lower TCO
For 40 years ABB has evolved its lineup of large industrial robots to meet modern manufacturing needs. This depth of experience has led to a comprehensive knowledge of the needs of our customers and the technical capability to produce the most robust and cost effective machines available. In November 2013, ABB unveiled the first four members in the family of its 7th generation of large robots—the IRB 6700. Today, ABB once again raises the bar for others to attain with the introduction of two additional variants, the IRB 6700-155/2.85 and the IRB 6700-200/2.60.
Not only have accuracy, payload and speed been increased, but power consumption has been lowered by 15 percent and service has been simplified. In determining what improvements to include, ABB studied the detailed field reports from the IRB 6700’s predecessor and engaged closely with customers during a yearlong study.
“Historically, when designing our robots we have always focused on performance. This time we emphasized reliability and lowering total cost of ownership,” says Ola Svanström, ABB Product Manager for Large Robots. “The IRB 6700 focuses on MTBF (mean time between failures), MTTR (mean time to repair), and the essential elements required to achieve these objectives.”
Every robot in the 6700 family has been designed to accommodate Lean ID—a new Integrated Dressing (ID) solution meant to achieve a balance between cost and durability by integrating the most exposed parts of the dress pack into the robot. “Our automotive customers have told us it is not unusual to change a spot welding dress pack on 60% of their robots every year,” adds Svanström.“ Equipping an IRB 6700 with Lean ID makes it easier to program and simulate with predictable cable movements, creates a more compact footprint, and lengthens service intervals due to significantly lessened wear and tear. “This feature is going to be very popular with our customers because of its measurable benefits” says Paolo Maggi, Product Specialist at ABB Australia.
In designing the new robot, easier serviceability was identified as a critical aspect for improving its total cost of ownership. Access to motors has been improved, Service routines for the machine have been shortened and intervals between them have been increased.
