Service
Our manufacturing team is experienced in creating high precision components and assemblies. We specialise in complex, high risk, one-off designs with demanding tolerances.
ARA has an onsite manufacturing centre with a comprehensive range of equipment including modern CNC (Computer Numerically Controlled) and EDM (Electro Discharge Machining) machines:
We also have strong relationships with highly capable manufacturing partners including specialists in additive manufacturing with capabilities including:
Our fitting team can assemble components with micron precision, working closely with our inspection team to identify and then implement any adjustments required in order to achieve the required tolerances.
We work with a wide variety of metals including Titanium, Aluminium, Inconel, Stainless Steel and Tool Steel as well as non-metallic materials like SLA.
