ElectroCore Arabia successfully carried out multiple on-site slipring machining jobs at Saudi Cement and Eastern Province Cement facilities. Our mobile machining team performed precision re-machining of worn slipring surfaces on large motor and generator slipring assemblies, restoring proper contact surface finish and runout tolerance to eliminate sparking, overheating, and brush arcing issues. All work was performed on-site to minimize equipment downtime.
Scope of Work
- On-site inspection and measurement of slipring wear condition
- Runout measurement and surface roughness assessment
- Setup of portable slipring machining equipment on motor/generator shaft
- Precision machining of slipring contact surfaces to restore original diameter
- Groove machining and chamfering of slipring edges
- Surface finish verification to Ra 0.8 or better
- Concentricity and runout verification post-machining
- Brush holder alignment check and adjustment
- Brush replacement with correct grade carbon/copper-graphite brushes
- Brush seating and contact pressure adjustment
- Insulation testing of slipring assembly to earth
- Commissioning run and spark-free operation verification
