CNC MILLING

HIGH PRECISION MACHINING FOR PROTOTYPES, CUSTOM PARTS & PRODUCTION.

We provide high-precision CNC milling services, programmed with advanced CAD/CAM software for maximum efficiency and accuracy.

Our team uses custom jigs and fixtures to streamline production, reduce cycle times, and ensure repeatable results – whether you need a single prototype or a full batch of complex components.

All parts are machined in-house to your exact specification, with a focus on quality, consistency, and quick turnaround.

ADDITIONAL PROCESSES

We offer in-house processes such as rumbling & bead blasting to improve surface finish. We can also arrange external anodising, powder coating.

 

HELPFUL INFORMATION

FOR YOUR CNC PROJECTS

  • Simply email us your drawing or CAD file (STEP or PDF) along with quantities and any special requirements. We’ll review your project and provide a clear, no-obligation quote – we try and provide a quote on the day we receive your enquiry.

  • Lead times vary depending on part complexity and quantity, but we aim to turn around most jobs within 5–10 working days. For urgent projects or one-off prototypes, we’ll always try to accommodate shorter deadlines.

  • At Karpas Engineering, we’re more than just a supplier – we’re a hands-on partner in your project. You’ll work directly with experienced engineers who not only machine your parts, but also provide honest, practical feedback to help improve manufacturability and reduce costs.

    With in-house CNC milling, turning, laser services, and prototyping, we deliver fast, consistent results while supporting better design decisions and smoother production.

NEED MORE THAN JUST MILLING?

Alongside CNC Milling, we provide CNC Turning, Laser Marking, CAD Design, Prototyping, and final assembly services. This allows us to support your project from early design through to finished, ready-to-install components.
