Inscho Solutions Robot Service

When was the last time your facility scheduled servicing for its industrial robot? Chances are that it has been longer than the manufacturer’s recommendation. If your robot is over 3 years old it is time to start looking at backlash and servo over current for determining the overall health of your robot. We can provide a comprehensive health report on your robot. See downloads for an example.

Surprisingly, Inscho Solution Robot Service finds that a large number of industrial facilities invest anywhere from $26K for small, limited-function robots to millions of dollars for fully automated integration with support services — then neglect to schedule these costly investments for routine preventative maintenance at regular, recommended intervals. The reasons for this oversight aren’t exactly clear, but the results are. Lack of regular servicing on industrial robots can cost thousands in unnecessary bottom line expenditures.

As one example, a Fanuc 710 designed to provide some 15 years of performance will risk joint failure in as little as 7 years without recommended service, and could need replacement at a cost of approximately $24,000. Even worse, a 710 top loader might need to be replaced at a cost of about $108,000. Given that the average cost of preventative maintenance is about $2,500 every other year or so, it seems an easy decision to protect service life.

(To read how lack of preventative maintenance cost one plant $16,986 earlier this year, click here.) In some cases, the risk created by lack of regular robot servicing may actually occur before the time frame specified by the manufacturer, depending upon the robot’s usage.

Fanuc recommends service at 11,520 hours (710/410), but aggressive programming can really stress an axis like J5/6, justifying even more frequency. When grease leaves the bath with the rancid odor and consistency of a watery creosote, you have to agree it may have lost all its lubricating qualities. This can occur in as little as 9,000 hours. This is not the only situation that requires a more frequent look at the lubricant of a drive mechanism. In some instances operations that required wash down have introduced high pressure water through the seals, creating an emulsification that when exiting the grease bath had the color of milk creme. (See photo at right.) The normal coloration should be more of an “orange marmalade”. In areas of high temperature change, condensation can reduce lubricating qualities.

The photo above is an example of a side mount carriage bearing which will have to be replaced at a cost of a little over $5,000 with parts available in 4 weeks. This is the least amount a repair due to lubrication issues is going to cost a facility. All operations are different and need to be assessed individually for a true indication of a safe lubricant replacement strategy.

Inscho Solutions robot maintenance service includes replacing grease, servo memory batteries, controller memory battery, purge and clean up. This is a tedious and time-consuming task best conducted by a trained professional rather than an in-house maintenance staff.

  • To extend the life of your valuable asset, it’s worth considering these questions:

  • How long can your robot be down before the bottom line is impacted?

  • How long has it been since your last robot service? Can you afford to wait?

  • Do you have run hours logged to see when you are getting close?

  • Is the questionable grease being reviewed for determining a safe replacement frequency?

  • Who does your service? Have they provided you a health report?
