When a part moves from prototype into regular demand, the priorities change: unit cost, cycle time and batch-to-batch consistency start to matter more than one-off flexibility. We set up dedicated fixtures and locked programs so every run repeats the one before it.
Set Up for Repeat Runs
Volume work lives or dies on material consistency. We standardise the grade and the mill source per part number, so the stock that arrives for run three behaves like the stock from run one.
Fast to cut, dimensionally stable and cheap to anodize, which makes aluminum the default choice for enclosures, brackets and heat-transfer parts at volume.
Chosen where corrosion resistance and cleanability are specified rather than optional. Harder on tooling than aluminum, so cycle times and tool-life planning matter more in the quote.
The workhorse where load and cost both matter. Alloy grades add hardenability and fatigue life, which typically means heat treatment after machining and grinding to finish.
High conductivity with excellent machinability. Brass in particular machines fast enough that cycle time per part stays low even on tighter tolerances.
Specified for strength-to-weight or heat resistance that no other grade delivers. These cut slowly and wear tooling fast, so we plan the tool path and the tool budget into the volume price from the start.
For volume runs where a machined plastic part beats a molded one: low tooling cost, no mold lead time, and design changes absorbed without cutting steel.
We machine production batches under strict confidentiality to protect customer designs. No minimum order quantity on the first run — talk to us about the volumes you expect.
Volume machining is a different discipline from prototype work: it rewards process stability, tool-life planning and unattended hours rather than setup flexibility.
Multi-pallet machining centres keep spindles cutting while parts load and unload, which is where volume cost actually comes from.
Bar feeders turn round parts around the clock with minimal intervention, which is normally the cheapest route to a high-volume cylindrical component.
Five-axis and mill-turn platforms machine several faces in one setup, which cuts fixtures, handling and the stack-up error that comes with both.
We design and build the workholding in-house. For volume work the fixture decides cycle time and repeatability far more than the machine does.
Holding a tolerance on part one is straightforward. Holding it on part five thousand requires process capability, not just skill at the machine.
Turnkey delivery including surface treatment, hardware installation and kitting, so parts arrive ready to build rather than needing another supplier.
Project focus: bore alignment & batch consistency across the annual volume
4-Axis CNC Milling + Boring
A356 Aluminum Casting
30,000+ Units
A Tier-1 automotive supplier needed transmission housings and covers machined as a matched set. Bearing bore alignment between the two parts is what keeps the gear train quiet, and variation between batches showed up downstream as noise and premature bearing wear.
We built a dedicated tombstone fixture that machines the housing in two operations with the bores finished in the same clamping as the mounting face, then locked the program and tool offsets for the life of the run.
Focus: repeatable finish & full material traceability by batch
CNC Turning + Swiss Machining
316L Stainless Steel
5,000 pcs per Release
A medical device manufacturer needed instrument components turned in repeated batches over several years. Every release had to match the original approval sample, and the material had to be traceable back to the mill heat.
Parts run on Swiss-type lathes with bar feeders, using a locked program and a fixed tooling package. Process records are retained against the part number so a later release is reproduced rather than re-engineered.
Focus: cross-hole alignment & pressure-tight sealing
CNC Milling + Deep-Hole Drilling
6061-T6 Aluminum / Ductile Iron
±0.025 mm
An industrial power company needed hydraulic manifold blocks in recurring batches. Internal cross-holes have to intersect cleanly for flow, and every sealed port has to hold pressure with no leakage at test.
Manifolds run on horizontal machining centres with pallet changers, using through-tool coolant for the deep holes and a controlled deburring operation that follows the same tool path.
Focus: cosmetic surface quality & anodize-ready finish at volume
3-Axis Milling + Tumbling + Anodizing
6061-T6 Aluminum
Anodized, brushed or bead blasted
A consumer electronics brand required enclosure sets machined in production quantities with a consistent cosmetic finish. A visible tool mark on one part in the batch is a reject, and anodizing amplifies surface defects rather than hiding them.
We ran the enclosures on dedicated fixtures with high-speed spindles and light finishing passes, then specified a tumbling and bead-blast step before anodizing to even out the surface across the whole batch.
Our production cells run multi-axis machining centres and bar-fed lathes with tool-life management and in-process gauging, set up for repeat batches rather than one-off parts.

We are your professional production partner. Talk to our engineers about capacity, scheduling and the volumes behind your programme.
On a production run, the figures that matter are the ones you would put in a supply agreement. These are the targets our production cells are managed against.
This service is built for batches from 500 pieces upward. Smaller quantities run through our standard CNC machining service.
Critical features are trended against a capability target rather than accepted on pass or fail, so drift is caught early.
Confirmed per order against quantity and finishing route. Repeat runs are usually faster because fixture and program already exist.
Every batch ships with an inspection record covering critical dimensions, with FAI and material certification available.
A streamlined workflow that removes unnecessary time cost and keeps your programme moving from drawing to delivered batches.
Upload drawings with quantities for volume pricing and a manufacturability review.
We plan the routing, workholding and tool life before the first part is cut.
A full dimensional FAI is produced and approved before the batch is released.
Batches run with in-process gauging and capability trending, not end-of-run sorting.
Surface finishing, hardware installation, kitting and global dispatch.

For us, high-volume production starts at roughly 500 pieces and runs upward through recurring batches. Below that, parts are better served by our standard CNC machining service, where setup is amortised over a smaller quantity and the fixture investment is not justified.
The practical threshold is economic rather than technical: once the fixture and program cost is spread across enough parts, the per-piece price drops sharply on the second run and stays there.
The engineering effort moves from making one part to making the same part identically, repeatedly, at a predictable cost.
Fixturing: a dedicated fixture replaces general workholding, so location is repeatable without operator judgement. Tool life: cutting tools are changed on a schedule derived from cut time, not when they fail. Process control: critical features are trended with SPC so offsets are adjusted before parts go out of tolerance. Capacity: pallet changers and bar feeders add unattended hours that a prototype job never uses.
Standard machined tolerances are ±0.025 mm (±0.001 in), with precision features held to ±0.005 mm (±0.0002 in) where the drawing requires it. The more useful figure on a volume run is process capability: we target a CPK of 1.33 or better on critical features, which is what actually guarantees the last part in the batch matches the first.
Aluminum alloys, stainless steels including 304, 316L and 17-4 PH, carbon and alloy steels, copper and brass, titanium and nickel alloys, plus engineering plastics such as POM, PEEK and nylon. On volume work we standardise the grade and mill source per part number, and hold the material certificate against each batch so a later run is cut from comparable stock.
By retaining the process rather than re-deriving it. For each part number we keep the program, fixture, tooling package, inspection plan and the recorded offsets. A repeat order runs against those records instead of being set up from scratch.
Within a run, in-process gauging feeds SPC trend charts, and the inspection record ships with the batch so you can see the actual distribution rather than a single pass or fail result.
As-machined finish is Ra 3.2 µm (125 µin), with fine machining reaching Ra 0.8 µm. For production quantities we normally add a tumbling or bead-blasting step, because it evens out the surface across the whole batch rather than only on the parts that happened to cut cleanest.
Decorative and protective finishes including anodizing, plating, passivation and powder coating are coordinated before dispatch.
Tooling is the largest variable cost in volume machining, so it gets planned rather than discovered. We calculate expected tool life per operation from the material and cutting parameters, schedule changes by cut time, and quote the tooling consumption into the per-piece price. On hard or abrasive materials such as titanium and glass-filled plastics, that planning is usually what separates a competitive quote from an optimistic one.
Yes. Surface treatment, insert and hardware installation, riveting, light sub-assembly and kitting can all be included, with volume-appropriate protective packaging for the parts. Consolidating those steps with the machining removes a second supplier from your schedule and keeps responsibility for the finished component in one place.
Standard production batches typically run on a 5–10 working day cycle, confirmed against your quantity and finishing route. Repeat orders are usually faster because the fixture, program and tooling already exist. Where a programme needs scheduled releases across a year, we can plan capacity against those dates rather than quoting each batch separately.
