Capabilities

At Sterling Machining, our CNC capabilities are built around one core principle: precision across every material. Whether you need stainless steel valve components, complex aluminium housings, or Inconel parts for extreme environments, we have the tools, expertise and processes to deliver.

Our CNC turning capacity covers diameters from 10 mm to 500 mm and shafts up to 3.5 metres long — perfect for aerospace, oil & gas and extrusion applications. On the milling side, we offer 4-axis machining with travels to 1500 mm, enabling high-accuracy multi-face operations in fewer setups.

We routinely hold tolerances to ±0.01 mm and achieve surface finishes to Ra 0.8 µm, even on exotic alloys like Monel, Waspaloy or Super Duplex. Our cutting strategies and tooling are optimised by material type — with custom feeds, speeds and toolpaths ensuring repeatability and process control from first-off to final batch.

For polymers and non-ferrous metals, we take extra care to minimise heat distortion and produce burr-free finishes. All work is backed by an ISO 9001:2015-certified quality system and a team with decades of hands-on experience in low-to-medium-volume manufacturing.

Our in-house team also supports rapid prototyping, fixture design and material sourcing — including heat treatment, grinding, and surface coatings via trusted partners. If you’re looking for a reliable partner to machine the materials your designs demand, we’re ready to help.
