CNC Milling
At GPR Ltd, our CNC Milling services deliver exceptional precision and quality. Based at our Camberley facility in Surrey, we serve prototype, small‑batch and production requirements across aerospace, medical, automotive, telecoms and general engineering sectors.
We are fully accredited to BS EN ISO 9001:2015, ensuring robust quality management at every stage. Our highly skilled workforce operates state-of-the-art CNC milling machinery—capable of both 3-axis and advanced 5-axis machining—enabling us to produce parts with complex geometries while maintaining tight tolerances and excellent repeatability.
Advanced Capabilities
- High Precision 3 & 4 axis CNC Milling of metals and plastics
- 3 Axis Machining: Ideal for flat and prismatic components. We deliver fast, accurate milling for prototypes and quick-turn manufacturing without compromising finish.
- 5 Axis Machining: Our investment in dual Matsuura MX-520 5 axis mills enables us to handle intricate, freeform components in fewer setups—reducing cycle time and improving accuracy. It’s perfect for parts with undercuts, multi-angle faces, and complicated contours.
- Materials Expertise: We machine a wide range of materials—including aluminium, stainless steels, brass, titanium, and engineering plastics like Delrin and PTFE—tailored to your project’s demands.

CNC Machining Process
01. Design Input & Quotation
Upload CAD/DXF files, and we’ll provide a competitive, no-obligation quote after reviewing material, tolerances, geometry, and finish requirements.
02. CAM Programming
Our in‑house programmers develop optimised toolpaths tailored to your part, ensuring efficiency and geometrical accuracy.
03. Prototype Milling
We run initial prototypes on either 3‑axis or 5‑axis mills, including first‑piece inspections to confirm precision before progressing to full batches.
04. Quality Inspection & Reporting
All components undergo inspection via calibrated CNC CMMs or manual gauges. We supply comprehensive inspection documentation aligned with ISO 9001 standards.
05. Finishing & Secondary Processes
Available services include deburring, polishing, anodising, painting, and part marking—delivered in partnership with trusted specialist subcontractors as needed.
06. Delivery & After Sales Support
We ensure on-time delivery with full traceability documentation. Our dedicated support is always available to discuss performance, reorders, or custom process adjustments.
