An Example in Steel Casting    Traction Motor Rotor Disc

Quality Assurance

The rotor is inspected for quality, dimensions, and finish.

  • Out of the mold, the casting is inspected visually for surface finish and for misruns in the ribs and surface holes and shrinkage in the hub and on the rim. As-cast dimensions are measured for tolerance.

  • After heat-treatment, the rotor is inspected for hardness on the hub.

  • After machining, the critical surfaces are measured for dimensions and surface finish.
