High Speed Technologies, Inc. can repair damaged air bearing spindles that are used in dicing and back grinding. A common cause of failure on these spindles is coolant leakage through the motor coolant jacket.<\/p>\n
Because most dicing spindles are rather compact the motors require water cooling.\u00a0 Often dicing facilities use the same DI water to cool the motors that they use in their cutting process. DI water is very aggressive toward certain metals and can actually dissolve them.<\/p>\n
Eventually the water jacket will begin to leak coolant into the spindle. When this happens imminent spindle failure is on hand. Once a leak is propagated the spindle can fail in several ways usually with a radial crash. If the leak remains the water can propagate into the electronics or motor windings and cause extensive damage.<\/p>\n
