The upper pinch roll housing for a steel roll manufacturer was damaged beyond repair. Adding to that challenge, there were no OEM prints available to be used as reference for the fabrication and machining. Our team reverse engineered the part, dimensionally inspecting the existing component and generating the manufacturing prints while verifying all critical fits and dimensions. The new rolling mill housing was fabricated and machined based on our engineering team’s drawings. After completing all machining and meeting all technical requirements, the new bearing sleeves were installed into the housing. The manufactured new rolling mill housing was delivered machine-ready within the production schedule.
