The operator noticed unusual spindle noise, vibration marks on finished components, and a gradual drop in machining accuracy. What seemed like a minor issue was beginning to impact production quality and machine performance.
DMG BT50 Spindle Repair Case Study
A customer approached us with a DMG BT50 spindle experiencing excessive vibration, bearing noise, and inconsistent machining accuracy during machining operations.
What we found during inspection:
1) Bearing wear inside the spindle assembly
2) Excessive taper runout
3) Internal contamination
4) Reduced spindle stability
Repair work carried out:
1) Complete spindle dismantling and inspection
2) Precision bearing replacement
3) Taper restoration and correction
4) Dynamic balancing
