Some Featured Repairs
HST Job I-9127 Our customer crashed this DMG Mori NMV 500 in the “Z” axis with a 0.250 tool. Fortunately there was no damage to the shaft or housing. The customer could feel what they described as a “flat spot” when turning the spindle by hand. We discovered slight brinelling on the # 1 bearing. In this case the crash might have been a small blessing in disguise. When we opened the spindle up we discovered severe contamination in the # 1 & #2 bearings and failure was imminent. Catastrophic bearing failure while operating at high speed could have caused worse damage than the crash.
