  High run-out in your Nakanishi Control Unit can stem from several issues. It could be due to a bent tool, which requires a tool replacement. Alternatively, the collet nut might not be correctly installed; ensure it is properly secured. If the collet and collet nut are worn, replace them. Contaminants inside the collet, collet nut, or spindle can also cause this, so cleaning these components is advised. In more severe cases, worn ball bearings or the inside of the spindle being worn might be the cause, requiring a replacement of the ball bearings or spindle shaft by Nakanishi dealer service.
