Our customers process creates an abundance of small chips that are difficult to remove from the spindle during the manufacturing process due to the geometries of the part they manufacture. These chips work their way into the space between the spindle shaft and housing and over time rub the rotating parts damaging the spindle. We have been able to extend the spindle life considerably through proper repair practices. We replace the worn parts of the spindle with parts manufactured in our machining and grinding departments and make sure the tolerances are as tight as possible decreasing the possibility of chips getting into areas where they can damage parts.
