Endeavor Technologies specializes in rebuilding oil-cooled spindle motors such as the Fanuc A06B-1389-B392#0040 employed in the Mitsui Seiki HT4A. Service to this special motor should not be attempted by unqualified or inexperienced personnel!
Rebuilding your A06B-1389-B392#0040 begins with a thorough inspection to determine what parts are worn, whether the winding is still in good condition, and whether or not the pulse generator is faulty. If a new winding is required, we will duplicate the factory winding right down to the special Hitachi lead wire, stocked only here at Endeavor Technologies. We can even upgrade the winding with our Epox-E-Pak insulation system to better protect it against contamination and extend its life expectancy. High speed motors in demanding applications such as the A06B-1389-B392#0040 require that nearly all surfaces that capture bearings—shaft diameters, bearing bores, bearing retaining caps, etc… are precision ground to tight tolerances to minimize run out and vibration in the assembled motor. Endeavor Technologies has the capabilities in our machining department to fabricate new or refurbish these parts to like-new condition when replacements aren’t available from the manufacturer. Endeavor Technologies stocks the special bearings required to rebuild this motor along with replacement pulse generators, metric O-rings for the water jacket, etc…
After dynamic balancing and assembly, the water jacket is pressure tested and your Fanuc motor A06B-1389-B392#0040 will be run in to full speed on our test stand that has provisions for liquid cooling. Running temperature, bearing temperature, current, and vibration levels are recorded, along with shaft TIR and other mechanical assembly details. Don’t entrust the service of this critical part of your machine tool to someone less experienced and qualified.
