Precision CNC Milling in Leighton Buzzard
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's the method of choice for parts that require features on multiple faces or intricate geometries that turning alone cannot achieve.
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 — 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?
CNC milling costs depend on material, part complexity, number of setups required, tolerances and batch size. We use CAD/CAM simulation to provide accurate quotations before any machining begins. Contact us with your drawings or 3D models and we'll provide a detailed quote, typically within 24-48 hours.
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.
