CNC Machining
Integrated CNC Machining for High-Performance Components
Our CNC machining capability delivers accuracy, repeatability, and surface integrity for complex metal components. Our machining approach is incorporated throughout the complete manufacturing lifecycle, from early-stage design collaboration to the delivery of certified, fully finished parts.
Our engineers understand how material behaviour, casting processes, and downstream machining interact, enabling smarter tolerances and improved performance. With advanced CNC equipment and highly skilled machinists, we support both development programmes and low-to-medium volume production.

Machining Equipment
Precisely machined components are finished on modern CNC 4- and 5-axis machining centres. Fully equipped with in-line measuring probes, parts can be finished consistently and repeatedly to tight, precise tolerances.
Components manufactured from centrifugal and sand castings are proof-machined prior to precision-finishing to drawing. Bushes and sleeves for power generation valves, galvanising steel sheet equipment, and piston rings for marine engines are produced on these machines.
Precisely machined components are finished to extremely exacting dimensions on the most modern machining centres which are fully equipped with in-line measuring probes. This equipment permits finishing of components consistently and repeatedly to the most exacting tolerances. Can hold tolerances of 0.010mm.
Our Hurco 5-Axis CNC Milling Machine allows for full 5-Axis milling of complex shapes and geometries in various wear- and corrosion-resistant superalloys, ranging from 20-65 Hardness Rockwell C.
Typical end applications and industries for such precisely machined components include Homogenising Pumps & Valves, Food & Pharmaceuticals, Oil & Gas, Motorsport, Aerospace, Glass Mould repairs, and others.
Components requiring grinding are finished on our state-of-the-art CNC grinders, achieving extremely fine tolerances to better than 0.02mm and high surface finish. Components include parts for pumps with high processing pressures which demand accurate metering of chemical products.
Many components are specified to extremely low micron surface finishes for customers requiring extremely smooth, flat component surfaces. These are achieved using our state-of-the-art honing and lapping equipment.
Machining permits complex profiles in wear-resistant materials to be produced cost-effectively and to high precision. Wall Colmonoy’s comprehensive array of wire cutting machines enables components from a few grams to many kilos to be produced to finished drawing.
Our Facility
Precision machining is performed in-house on modern CNC machining centres within our 2180m2 machine shop at our Pontardawe, Swansea, UK facility, forming part of a fully integrated, end-to-end manufacturing environment. By co-locating machining with casting, inspection, and post-processing operations, we maintain control over quality, scheduling, and performance at every stage of production.
