Precision CNC Milling Services for the UK
Clarent Precision provides subcontract CNC milling services to manufacturers across the UK from our ISO 9001 certified facility in Leighton Buzzard, Bedfordshire. CNC milling is a subtractive manufacturing process in which rotating cutting tools remove material from a fixed workpiece to create complex shapes, pockets, slots and 3D profiles. It is the method of choice for parts with features on multiple faces or intricate geometries that turning alone cannot achieve.
Typical milled work includes housings, manifolds, brackets, mounting plates, enclosures and weight-optimised billet components. From billet aluminium motorsport parts to Inconel aerospace components, the same machines, inspection regime and traceability apply to every job.
At Clarent Precision, our 3 and 4 axis machining centres allow us to produce everything from basic 2D profiles through to complex 3D parts. The 4th axis adds rotation, enabling us to machine multiple faces in a single setup, reducing lead times and improving accuracy by eliminating repositioning errors.
We have full CAD/CAM facilities that allow us to accurately interrogate your 3D models, ensuring all dimensions are correct to specification before machining begins. Using simulations, we provide accurate prices and lead times upfront, with no surprises.
Materials We Mill
Our material range goes well beyond the standard. We regularly mill exotic super alloys that most UK sub-contract machinists won't touch.

Frequently Asked Questions
What is the difference between 3-axis and 4-axis CNC milling?
A 3-axis CNC mill moves the cutting tool along the X, Y and Z axes, which is suitable for most 2D and simple 3D features. A 4-axis mill adds rotation around one axis, allowing us to machine features on multiple sides of a part without repositioning. At Clarent Precision, our 3 and 4 axis machining centres handle everything from basic 2D profiles through to complex 3D shapes.
What tolerances can your CNC milling achieve?
We routinely hold tolerances of ±0.01mm on our CNC machining centres. All parts are inspected in our temperature-controlled inspection department using a CMM, micrometers, bore gauges and other precision measuring instruments. Full CMM reports are available on request.
What materials can you CNC mill?
We mill a wide range of materials including aluminium, stainless steel (all grades), brass, mild steel, and engineering plastics. We also specialise in difficult-to-machine super alloys such as Inconel, Titanium, Hastelloy C276, Super Duplex and Nitronic 50, materials that most sub-contract machinists won't touch.
How much does CNC milling cost in the UK?
UK CNC milling is usually quoted per part rather than per hour. The main cost drivers are material choice, part complexity, the number of setups required, tolerances and batch size. A part that can be machined in one setup on our 4th axis costs less than one needing multiple repositions. We use CAD/CAM simulation to provide accurate quotations before any machining begins, typically within 24-48 hours of receiving your drawings.
Where are you based, and do you supply UK-wide?
Our facility is in Leighton Buzzard, Bedfordshire, within easy reach of Milton Keynes, Luton, Bedford and the wider South East. We supply CNC milled parts to customers across the whole of the UK, with couriered delivery on every order and scheduled call-off deliveries available through our stockholding service.
What batch sizes do you support for CNC milling?
We produce CNC milled parts in any quantity from a single prototype through to production runs of 1,000+. Our full CAD/CAM capabilities mean we can efficiently machine both one-off complex parts and repeat production batches. We also offer a stockholding service for regular call-off orders.
What is the maximum part size you can mill?
Our CNC machining centres can accommodate parts up to 762mm x 406mm x 508mm. If your part exceeds these dimensions, please get in touch. We may be able to suggest alternative approaches or refer you to a suitable partner.
