CNC TURNING

HIGH PRECISION MACHINING FOR PROTOTYPES, CUSTOM PARTS & PRODUCTION.

We offer precision CNC turning with Y-axis milling capability, ideal for complex parts and tight-tolerance features. Programmed in-house using advanced CAD/CAM software, our setup is optimised for efficiency, consistency, and quick turnaround.

Whether it’s a one-off prototype, a short production run, or a custom component, we machine every part to your exact specification – reliably and with the personal service you’d expect from a family-run workshop.

To keep even our older machines sharp and efficient, we developed LEGACY Connect – our own wireless file transfer device, now used in-house and by other UK workshops.


PRECISION YOU CAN HOLD

CNC turning is where accuracy meets simplicity — round parts, threads, bores, and shoulders, all cut cleanly and consistently.

Whether it’s a one-off spacer or a full batch of precision-turned components, we machine everything in-house using CNC lathes built for tight tolerances and fast turnaround.

• CNC turning in stainless, aluminium, brass, & plastics
• Shafts, pins, bushings, threads, custom components
• Trusted by UK engineers, designers, and manufacturers.

We deliver real parts, real production — without the wait.

Send us your drawing — we’ll take care of the rest.

HELPFUL INFORMATION

FOR YOUR CNC TURNING PROJECTS

  • CNC turning is ideal for manufacturing cylindrical or symmetrical components such as shafts, bushings, spacers, and threaded parts — perfect for automotive, aerospace, robotics, and industrial applications.

  • We CNC turn aluminium, mild steel, stainless steel, brass, bronze, copper, engineering plastics (like Acetal and Nylon), and more. Need help choosing a material? Get in touch.

  • Yes — our lathes have Y-axis milling and live tooling, allowing us to machine complex features like milled flats, cross-holes, slots, and keyways in a single setup.

  • Absolutely. We specialise in low-volume production, one-offs, and prototypes — ideal for product development, testing, and short batch runs.

  • Prototype and low-volume turned parts are typically ready in under 2 weeks. Lead times for batch production vary, and we always confirm upfront. Express options available.

  • Yes — we can produce a wide range of features including internal and external threads, milled flats, cross-holes, grooves, and custom profiles. Our live tooling and Y-axis capabilities allow for precise multi-operation parts in one setup.

  • We manufacture CNC turned components for a wide range of industries, including electronics, automation, robotics, lighting, packaging, automotive, and product development. Our customers range from startups and R&D teams to established UK manufacturers.

  • We offer in-house CNC turning with fast lead times, transparent communication, and a focus on quality. Based in Hertfordshire, we support UK manufacturers with precision parts and expert advice.
