Analysis
Our technicians thoroughly inspect the spindle to identify the problem correctly before moving ahead with any spindle repair work. All spindles are subjected to the following 5 point assessment:
Incoming Vibration Analysis
Assembled Spindle Inspection
Disassembled Spindle Inspection
Bearing Condition
Engineering Recommendations
Incoming Vibration Analysis
- Incoming vibration analysis is performed in order to determine: bearing condition, level of unbalance, non-repetitive runout.
Assembled Spindle Inspection
- Pilot ID or taper runout on tool end of shaft to determine possible spindle crash or improper tooling.
- Rear taper runout inspection to determine possible over tightening of belts or improper tooling.
- Preload test to determine bearing wear or spindle crash.
Disassembled Spindle Inspection
- Pilot ID or taper inspection to determine spindle crash, improper tooling or overheating. Bearing journal inspection to determine improper bearing fits or use of spindle after initial failure.
- Overall shaft condition to determine crash, overheating, lack of coolant or overloading.
Bearing Condition
- An inspection of bearings is performed under lab conditions by factory trained bearing specialists to determine lack of lubrication, over speeding, spindle crash, overloading, loss of preload, contamination (coolant or other material) or overheating due to electrical problems. In addition, we have the access to all Bearing OEM’s facilitation and personnel.
Engineering Recommendations
- We recommend spindle design changes or enhancements to improve spindle longevity and/or performance. For example, if a spindle has failed due to contamination, a design change such as new labyrinth nuts, air purging, hybrid bearings or improved sealing design will be recommended and implemented.
