MPA Power offers excellent rotor and compressor shaft grinding damage repairs for equipment performance. Our intensive process begins with a pre-inspection. The condition of the shaft will be a detailed account. The in-situ dye penetrant and magnetic particle testing of hardness and fractures make measuring an easy task. The health of the shaft next undergoes tests for displacement and trueness. Our team sources the best solution according to the pre-inspection report and level of damage. To reach OEM taper and ovality specifications (to within 0.02mm for roundness and alignment), the damaged fillet radius portions may require careful regrounding or the crankshaft may need grinding on the field. We use world-class methods to prepare a surface polish of better than 0.30 µm Ra. This optimizes rotor or compressor shaft performance and lifespan.
