Tailshaft Machining

Crankshafts are often subjected to increased hardness and bending (runout) due to high heat exposure and rapid cooling following a failure. This process frequently leads to conditions that exceed OEM tolerance limits, resulting in significant stress on the component.

At Royce Onsite Machining, we employ specialised ceramic blankets to carry out controlled crankpin annealing—a precise heat treatment method aimed at decreasing both hardness and runout. When used alongside our advanced precision machining services, this technique effectively restores crankshafts to meet OEM specifications.

Our annealing process can lower crankpin hardness by up to 300 HB, effectively mitigating harmful excess hardness and considerably enhancing the longevity of your crankshaft.

Our expert team specialises in on-site machining services for a diverse range of construction assets across industrial, commercial, and residential building sites. We provide precision line boring for major infrastructure projects, such as nuclear power plants and bridges, as well as metal stitching for storage tanks and docking facilities. Our commitment is to deliver expert repairs precisely where they are required.

We recognise that time is of the essence in construction projects. That’s why we offer a 24/7 service to minimise downtime and prevent project delays. Many construction assets are either too large or permanently installed, making off-site repairs impractical. Our on-site machining solutions eliminate the need for dismantling, saving you both time and money while ensuring unmatched precision and reliability.

At Royce Onsite Machining, we understand the critical need to minimise downtime and swiftly restore your vessel to operational status. Our experienced team of engineers has been providing support to the marine and shipbuilding industry for decades.

As a consequence, Royce Onsite Machining has earned a reputation as a leading company worldwide, renowned for delivering high-quality marine machinery repair services.
