News: Nuclear AMRC machining at 1000mph

By

The Nuclear AMRC in Rotherham is playing a key role in the Bloodhound SSC project to create a 1000mph car and enthuse a new generation about engineering.

The British engineering showcase aims to break the world land speed record by achieving the supersonic speed of 1,000mph. It also aims to inspire future generations to take up careers in science, technology, engineering and mathematics (STEM) by showcasing these subjects in the most exciting way possible.

The machining team at the centre on the Advanced Manufacturing Park is producing seven parts of the rear sub-frame that will hold the rocket into the car, with some parts measuring over a metre in length and width.

Jay Shaw, deputy machining group manager at the Nuclear AMRC, said: "These are high tolerance parts that we’re machining from aerospace-grade aluminium.

"It's going to be holding 27,000 pounds of thrust, so our knowledge and capabilities for large parts which will operate under the toughest conditions will be critical."

Some of the frame components will be machined on the centre's new state of the art equipment. Delivered in October, the Hermle C60 is an extremely versatile five-axis mill-turn centre capable of working on parts up to 1.2m diameter by 90cm high and 1.4t weight.

Shaw added: "It's a good test for the Hermle – we'll test the accuracy and our knowledge of the machine. It's ideal because the Hermle is a full five-axis machine so we can do intricate three-dimensional features quite easily."

The collaboration began early in the summer, when Shaw met with Bloodhound engineers to advise on tolerance and features for the parts. The work also involves several of the Nuclear AMRC's members. Sandvik Coromant is supporting on tooling, while Hexagon Metrology will inspect the final parts to ensure they meet specifications.

The Nuclear AMRC's sister centre, the AMRC with Boeing, has also carried out a range of work for Bloodhound. AMRC engineers produced gearbox parts for the Cosworth F1 engine which Bloodhound will use as a fuel pump, and calibrated the thrust ring for the rocket which successfully test fired in early October.

Rotherham high-tech precision engineering sub-contractor, Newburgh Engineering is a project sponsor and has completed Auxiliary Power Unit (APU) gearbox casings for use in the car.
