Our copper CNC machining services

Penta Precision provides high-quality copper CNC machining services to engineers, manufacturers, and OEMs across the UK. We deliver custom copper parts with exceptional accuracy, using advanced technology and ISO 9001:2015 certified processes. Whether you need prototypes or full production runs, our copper machining services ensure reliable results.

Our CNC copper capabilities include 3- and 5-axis machining centres with 24/7 automation. We support both complex and straightforward part designs, with rapid changeovers for production flexibility. You can rely on us for fast turnaround, repeatable quality, and clear communication throughout your project.

We’re trusted by customers across industries including electronics, construction, and automotive. Our copper CNC machining helps deliver parts that combine conductivity, strength, and visual quality. We also offer design advice to reduce cost and improve manufacturability.

Copper milling

Our copper milling service produces clean, accurate features across a range of part geometries. Using multi-axis CNC machines, we deliver reliable results for both detailed and simple components. Whether you need prototypes or full production, we provide efficient and precise service.

Machining copper can present challenges due to its softness and conductivity. We optimise tooling, feeds, and coolant strategies to avoid burrs, tool wear, and dimensional shift. This means your copper machined parts arrive ready to use, with minimal secondary processing required.

We work from CAD files, engineering drawings, or sketches to bring your design to life. Our CAM integration ensures a seamless transition from design to production. You get high-quality CNC copper parts delivered on time and to specification.

Copper turning

We manufacture copper turned parts using multi-axis CNC lathes and conventional turning equipment. This flexibility allows us to support everything from one-off prototypes to high-volume production. You receive parts that are clean, consistent, and dimensionally stable.

Our turning copper processes are refined for speed and accuracy. We use high-quality tooling and verified setups to produce repeatable results across every batch. You can count on Penta for dependable copper turning services at any scale.

Finishing Options

We offer several finishing processes to enhance the performance and appearance of your CNC copper parts. These include surface treatments for protection and finishes for visual appeal.

  • Polishing
  • Bead blasting
  • Part marking
  • Anodising
  • Plating
  • Ultrasonic cleaning

Components & applications

Our copper machined parts are used across sectors where performance, conductivity, and corrosion resistance matter. Whether for electrical systems, thermal management, or precision fittings, we provide parts you can trust.

We machine copper components to exacting standards, every time. Here's just a few common applications that we machine copper parts for: 

Electrical & conductive

Copper’s conductivity makes it a good choice for electrical applications.
- Busbars
- Terminals
- Connectors
- Transformers
- Instrument windings
- Electrical components

Thermal management

Because copper transfers heat efficiently, it is widely used in parts that manage or dissipate heat.
- Heatsinks

Rotating, sliding & wear

Copper alloys can be durable and smooth-running, suiting them to precision moving parts.
- Motor components

Housing & enclosure

Corrosion resistance and machinability mean copper is a dependable option for protective housings.
 - Enclosures

Structural & architectural

The attractive finish and strength of copper make it valuable in both functional and decorative structures.
- Building fascias
- Plumbing components

Support & utility

Copper’s machinability ensures accuracy in jigs and fixtures used in wider production processes.
