Radial crashes are the most common form of air bearing and dicing spindle failures. In a dicing, back grinding or other type of air bearing the rotating shaft is \u201cfloating\u201d on a cushion of air. This allows for super precise rotation. However, when the air supply is insufficient our when forces exceed the ability of the air cushion to support the shaft, it can contact the bearing journal. This is a crash.<\/p>\n
These crashes damage the radial bearing surfaces and jets. They can be caused by excessive feed-rate, mis-alignment, improper program input and contamination in the spindle air supply.\u00a0 HST has developed several technics for restoring radial bearing to like new condition regardless of the cause of the crash.<\/p>\n
