Metal Finishing
Our finishing processes refine the appearance and performance of machined parts. Deburring, polishing and surface treatments are applied to remove sharp edges, improve durability and deliver a high-quality finish suited to each application. By combining precision machining with tailored finishing, we ensure components not only meet specification but also offer the longevity and reliability demanded by production environments.
MRP System
Our MRP system ensures efficiency, traceability and on-time delivery. It integrates scheduling, material allocation, machine capacity and inspection checkpoints, so every component is monitored from order through to dispatch. This structured approach guarantees that customer projects progress seamlessly through design, machining, finishing and inspection, maintaining quality and delivery standards at all times.
Turning
CNC turning is carried out on our XYZ Proturn lathes, delivering precise diameters, shoulders and threads across steels, stainless alloys and exotic materials. Manual centre lathes complement our CNC capability for one-off and short-run parts. Together, this flexible setup enables us to produce shafts, pins, housings and bespoke components to exacting specifications, all backed by skilled operators and rigorous inspection.
Drilling
We perform drilling operations ranging from large radial-arm setups for heavy components to fine EDM small-hole drilling for intricate features. This breadth allows us to produce coolant holes, dowel holes and deep bores across a wide range of materials with accuracy and repeatability. Combined with our CNC machining centres, our drilling capability supports both standalone requirements and integrated processes within larger tooling projects.
Jig Boring
Our jig boring provides the ultra-precise hole positioning and alignment needed for critical tooling applications. Our Moore 2C borers, enhanced with CNC control and auxiliary high-rise capability, deliver sub-micron accuracy on complex jigs and fixtures. This ensures perfect positional relationships across tool steels, alloys and non-ferrous metals, supporting the tightest tolerances in press tools and precision assemblies.
CNC Milling & Boring
We leverage advanced CNC milling and boring to produce precision features and holes in steels, stainless alloys and non-ferrous metals. Our 3-axis milling fleet (Bridgeport and XYZ bedmills with automated tool-changers) handles profiling and complex contours, while our Correa CF20 & CF22 bed mill/borers perform heavy-duty bore operations up to 700 mm deep. Together with our integrated CAM toolset (VISI Machining, Artisan Ideas Master, Vero Machining Strategist and SmartCAM Freeform) we deliver repeatable accuracy, superb surface finish and rapid turnaround from CAD model to finished component.
CMM Inspection
Our Coordinate Measuring Machine (CMM) Inspection harnesses dual CMMs (Mitutoyo Euro M574 and DEA CNC A 001 CMMs), and our latest addition of the Keyence XM Series, to achieve sub-micron positional accuracy. We pair these with an OGP Smartscope 500 optical measuring system and Mitutoyo linear gauges, microscopes and projectors to catch the smallest deviations. Complementary comparators, hardness testers and a surface-measurement machine then verify form, finish and material properties before release, ensuring every component meets your exacting standards.
Tool Try-Out Facility
We rigorously test every press tool in our dedicated try-out bay using high-capacity presses, including HME 300 ton and 100 ton air-cushion units, a Rhodes 150 ton press and a flypress. By replicating real-world production loads and cycling, we confirm form, fit and function before delivery, ensuring each tool meets our exacting standards for performance, longevity and precision.
CAD CAM
At Alan Spargo Ltd, every project begins in our Design Office, where we use AutoCAD Release 2000 for detailed 2D drafting, Mechanical Desktop for parametric modelling and VERO-VISI CAD 3D for complex surface work. Sophisticated simulation tools validate form, fit and function virtually, reducing the need for physical prototypes and ensuring micron-level accuracy before machining begins.
Once the design is signed off, our integrated CNC machining suite takes over. We run 3-axis milling on 1 × Bridgeport VMC 600, 2 × Bridgeport VMC 1000, Correa CF20 & CF22 bed mills/borers, 4 × XYZ DPM bedmills and a Bridgeport GX1600, alongside our XYZ Proturn CNC lathe for complex turning. VISI Machining, Artisan Ideas Master, Vero Machining Strategist and SmartCAM Freeform drive seamless, repeatable workflows from CAD model to finished part.
Etching
At Alan Spargo Ltd, we employ the SINO-GALVO STJ-50F laser etcher to produce crisp, permanent markings on steels, stainless alloys and non-ferrous materials. Its galvanometer-driven optics enable rapid traversing across workpieces up to sizable plate dimensions, delivering fine text, logos and serial codes without mechanical contact. The result is burr-free, fade-resistant engraving with micron-level precision and repeatable quality across high volumes.
