This is a common question from prospective customers. When answering this question, it is important to address not only the typical life cycle of a robot, but also evaluate relevant need and standard changes for replacing a robot.
How long can I expect my new FANUC robot to last?
Many customers experience 10+ years of reliable service from their FANUC robots. FANUC tells us that a robot in a typical duty cycle application will run 80,000 to 100,000 hours without any failures. This is extraordinary given the amount of work a robot can perform in that amount of time.
As with all equipment, there are the usual caveats concerning proper maintenance during the life of the robot. What is not as well-known, and commonly ignored by inexperienced integrators, is the importance of proper initial setup of the robot. Applying proper setup parameters, such as load inertia values, is important to obtain the best life from your robot.
The cost to replace the robot can be divided into the following areas:
You may be able to avoid significant robot cell re-design by purchasing a late model, re-certified used robot. As a FANUC Level 4 Certified Servicing Integrator, Motion Controls Robotics, Inc has the ability to rebuild robots to original factory specifications.
The original cost of the robot and end of arm tool is typically some fraction of the cost of the entire robot cell. When it comes time to replace a robot, you will want to evaluate whether any of the other elements of the robotic work cell have reached their expected life. Conveyors and other load handling mechanisms need to be evaluated.
Robot cell safety is another area to evaluate. Robot Industries Association specifications (current version is RIA 15.06-2012, most recent previous version was RIA 15.06-1999) have evolved over the years, and the safety equipment in your robot cell may no longer meet latest industry standards, making them a candidate for upgrade/replacement. If you purchased your robot cell before 1999 and want to upgrade your robot, chances are you will want to update some or all of your safety equipment as well.
