Our Core CNC Machining Services
Elmax provides complete machining from raw material procurement through to finished, inspection-certified precision parts. Our core capabilities include:
- CNC milling service — 3-axis and 4-axis in-house, with access to 5-axis milling through trusted local partners for complex geometries
- CNC turning services — shafts, bushings, spacers and threaded components in mild steel, stainless steel, aluminium and non-ferrous alloys
- Cylindrical grinding services — superior surface finishes and tight roundness on pins, rollers and precision bores
- Keyway slotting — gears, pulleys and couplings for drives, conveyors and power transmission assemblies
Every job passes through our documented production process, ensuring consistency from first-off to final part.
CNC Milling and 5-Axis Capability
Our Stockport facility houses 3-axis and 4-axis CNC milling centres suited to prismatic parts, plates, brackets and housings. When components require complex 3D shapes and fewer setups, 5-axis milling completes them in a single setup — which we provide through established local partners with a proven track record.
- Milling tolerances of ±0.01mm on critical features are achievable depending on material and part size, tightening to ±0.005mm where required.
- CNC machines handle complex 3D shapes and geometries, making them the right choice for intricate parts that would otherwise need multiple operations.
- Typical work: aluminium medical housings, stainless food-grade blocks and mild steel construction brackets machined for North West OEMs.
- CAM programming and fixture design reduce cycle times and ensure consistent quality across repeat orders.
CNC Turning Services
CNC turning produces cylindrical components with high precision — our turning capability covers everything from small precision pins to larger shafts used in conveyors, mixers and automotive jigs.
- We produce stepped shafts, threaded connectors, bushings and spacers in mild steel, stainless steel, aluminium and engineering plastics, achieving tolerances as tight as ±0.01mm on turned features.
- Turning handles both prototypes and large-scale production — we set up fast for prototype runs of 5–20 parts and maintain stable processes for repeat batches into the hundreds.
- Turned parts are often combined with secondary milling, drilling or keyway slotting in a single setup, delivering complete cylindrical components without multiple suppliers.
- Milling and turning in-house means fewer handoffs, lower risk and shorter lead times for your supply chain.
Cylindrical Grinding and Keyway Slotting
Cylindrical grinding adds a level of finish and dimensional control that standard turning alone cannot reach. For applications needing fine surface finishes — typically Ra values below 0.8 µm — and close concentricity, grinding is the answer.
These services are critical for bearing journals, press-fit pins and rollers used in medical equipment frames, food-processing machinery and automotive fixtures supplied from the Manchester area. Tolerances as tight as ±0.005mm are achievable on ground features, delivering true high-precision results.
- Keyway slotting for gears, sprockets and couplings lets us supply ready-to-assemble drive components.
- Combining precision grinding and keyway slotting with CNC machining in one facility reduces logistics and lead times.
- This integrated approach eliminates shipping parts between suppliers, ensuring consistency and reducing risk.
Materials and Precision Engineering Expertise
Material selection directly affects part performance, machinability, cost and lead time. CNC machining is known for its material versatility, and our engineering team advises on the right choice for each application.
| Material | Grades | Typical Applications |
|---|---|---|
| Mild steel | EN3B, EN8 | Construction jigs, structural brackets, fixtures |
| Stainless steel | 304, 316 | Hygienic food and medical parts, corrosion-resistant assemblies |
| Aluminium | 6082, 7075 | Lightweight automotive brackets, housings |
| Engineering plastics | PEEK, Nylon, Acetal | Low-friction bushings, insulation components |
Beyond standard grades, we can machine titanium and specialist alloys for advanced applications, and source biocompatible materials for medical work where the end-use environment demands it. Where parts require heat treatment, anodising, passivation or bead blasting, we coordinate finishing through trusted subcontractors to deliver a complete solution.
Handling Complex Geometries and Tight Tolerances
Complex parts with pockets, intersecting bores, angled faces and tight positional tolerances demand both technical expertise and careful process planning. Precision CNC machining can achieve tolerances as tight as ±0.005mm on critical features, though feasibility depends on design, material and feature geometry.
- We use multi-axis setups, custom fixtures and probing cycles to keep features aligned and within specification.
- Experience with complex geometries means we know when a part needs additional setups or partner 5-axis capability — and we communicate that up front.
- Indicative tolerance ranges: bore diameters to ±0.01mm, flatness to 0.02mm, true position to 0.05mm — tighter where supported by design and material.
- Every complex component is backed by in-process checks and final inspection reports before despatch.
Industries We Serve and Typical CNC Machined Parts
Our industry experience spans more than two decades, delivering complex components across regulated and performance-driven sectors. That cross-sector knowledge means we understand what demanding specifications look like in practice.
- Food industry: stainless steel manifolds, mixer shafts, bearing housings and mild steel frames with food-safe finishes

Lead Times, Batch Sizes and Machining Partnerships
Elmax handles everything from a single prototype through small batches to ongoing production runs, with a flexible approach to volume and scheduling.
- Prototype and one-off parts (1–5 units): typically delivered in 1–4 weeks depending on complexity, material and finishing, supporting fast design iteration and testing.
- Small and medium batch production (6–100+ units): lead times of 5–7 weeks are common, shorter for repeat orders with established fixtures.
- Fast turnaround: simple, non-complex parts in standard materials can sometimes ship in days when capacity allows.
- Scheduled supply: long-term relationships unlock locked-in pricing, stable quality and reduced approval time for repeat jobs.
We encourage OEMs and engineering firms to view Elmax as a strategic machining partner — not an occasional supplier — and we coordinate finishing, heat treatment and other subcontract operations to deliver a single, integrated solution.
How to Start a Precision CNC Machining Project
Getting started is straightforward. Here's what to prepare:
- Drawings or STEP files with tolerances, material selection and surface finish requirements clearly defined
- Batch quantity and required delivery date
- Any special quality requirements — material certificates, inspection reports or specific quality standards
We encourage early contact during the design stage so our engineering team can advise on tweaks that reduce machining time and cost — our DfM feedback has saved customers both money and weeks of development. Based in Stockport with easy access to the M60 and the wider North West, we're well placed to support long-term partnerships.
