Services
CNC Milling
Our CNC milling capabilities handle complex 3D geometries using vertical and horizontal machining centres with up to 15,000 RPM spindle speeds. We process components up to 1 metre in length with 60-tool capacity magazines, supporting both prototype and batch production. Advanced programming software optimises toolpaths for precision in materials ranging from aluminium to exotic alloys.
CNC Turning
Specialist CNC turning services produce precision components with diameters up to 200mm using multi-axis lathes featuring sub-spindles and live tooling. Our machines enable simultaneous operations for complex parts, reducing setup times while maintaining tight tolerances. Capabilities include bar feeding systems for high-volume production of turned components.
Finishing and Assembly
Comprehensive finishing solutions include anodising, plating, and electropolishing through certified supply chain partners. We coordinate complete component assembly processes, ensuring final products meet exact specifications through rigorous inspection protocols before delivery to clients in aerospace and medical sectors.
Materials Machining
We machine diverse materials including stainless steel, titanium, Inconel, aluminium alloys, and engineering plastics. Our expertise extends to exotic metals like Hastelloy and Monel, with dedicated processes for flammable materials. Pre-machining services handle supplied blanks, forgings, and castings for precision component manufacturing.
Quality Inspection
ISO 9001-certified quality systems ensure 100% compliance through advanced measurement equipment including Mitutoyo CMMs and surface finish analysers. All calibration records are maintained online for immediate access, supporting traceability and adherence to aerospace, medical, and defence industry standards.
