**This notice is for market engagement only and is not a call for competition** The Atomic Weapons Establishment (AWE) is an arms-length body of the Ministry of Defence employing around 6,000 people headquartered in Aldermaston, Berkshire.

For more than 70 years, AWE has supported the UK Government's nuclear defence strategy and the Continuous At Sea Deterrent.

We also use our nuclear know-how and technical expertise to provide innovative solutions that support the UK's counter-terrorism and nuclear threat reduction activities.

We work at the extremes of science and engineering to understand the performance of nuclear warheads, and assess the safety, security and effectiveness of the stockpile in the absence of live testing.

Remarkable science, technology, engineering, and maths integrate across the lifecycle of the warhead: from initial concept and design to final decommissioning and disposal.

Experts in their fields work together in unique and advanced experimental facilities, to perform cutting edge experiments.

AWE is looking to engage with the market to understand supplier's capability to support the procurement of an ultra-precision 5 axis turn-mill machining centre.

The size of the machine is also vital to the procurement.

The available space is approximately 1300x1300x2400mm (wxdxh), therefore the machine suitably sized to fit.

The following items describe the machine specifications that this procurement must meet: • Dimensions of no more than approximately 1300x1300x2400mm (wxdxh) • The CNC 5 axis machining centre must be capable of milling on 3, 4 and 5 axes. • Spindle run-out shall not exceed 1μm. • Turning Roughness of <5nm Ra (on a 50mm sphere). • Turning Form Accuracy of < 50 nm (on a 50mm sphere). • The CNC 5 axis machining centre must be capable of diamond turning on 2 and 3 axes. • Milling Roughness < 10nm RMS. • Milling Form Accuracy < 2µm within 100mm of the work holding fixture. • The CNC 5 axis machining centre must be capable of milling on 3, 4 and 5 axes
