Acer Surface Grinder Spindle Repair
This Acer spindle is from a surface grinding machine. It is a coupling driven and grease lubricated spindle capable of running up to 3,600 rpm.
One of our New England customers was experiencing very poor part finish on their Acer surface grinder. When we picked up the spindle and its direct-drive motor one cause was immediately apparent. At some point, the rubber “spider” insert of the Lovejoy-style coupling had worn out. As the spindle continued to be operated, the spindle and motor halves of the coupling became heavily worn, as did the spindle-side drive key. Our inspection also showed that the bearing grease in both the spindle and motor was old & degraded, the wheel hub taper had excessive runout of >8µ and the taper threads had some superficial damage.
We performed a kiss grind on the hub taper to improve the runout and reworked the taper threads. We replaced the bearings & assembly screws in the spindle and motor, and installed a new drive key and motor coupling.
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
