What we do
Manufacturing Capabilities
One-stop CNC services, from a single prototype to repeat production runs.
CNC Milling
3-axis and 5-axis milling for complex geometries in aluminium, steel, titanium and engineering plastics.
CNC Turning
Precision turned parts with tight roundness, concentricity and surface finish control.
5-Axis Machining
Free-form surfaces and undercuts finished in a single setup — fewer operations, tighter true position.
EDM & Wire Cutting
Electrical discharge machining for hardened tool steel and internal features that milling cannot reach.
Surface Finishing
Anodising, plating, powder coating, bead blasting, polishing and laser marking.
Inspection & QC
CMM reports, surface roughness traces, hardness checks and full FAIR documentation on request.
Each process is covered in more detail in the capabilities section. Where two processes could both do the job, the comparison pages set out the trade-offs and name a winner.
Materials
44 grades in stock, 50+ available on request
Certified stock with mill test reports. Tell us the grade you need and we will quote against it.
The materials page lists every grade we stock by alloy family, with the stock forms available. Working in a grade that is not listed? Send us the spec — we source it.
Tolerances & finishes
Built to ISO 2768 — tighter on request
Standard and precision classes below are what we hold in normal production, not best-case single samples.
| Feature | Standard | Precision |
|---|---|---|
| Linear dimension | ±0.05 mm | ±0.005 mm |
| Hole diameter | H9 | H7 |
| Surface roughness | Ra 1.6-3.2 µm as-machined | Ra 0.4 µm on request |
| Parallelism | 0.05 mm | 0.01 mm |
| Perpendicularity | 0.05 mm | 0.01 mm |
| Concentricity | 0.03 mm | 0.008 mm |
Surface finishes available
- Anodising — Type II / Type III hard anodise
- Powder coating — any RAL colour
- Zinc / nickel / chrome plating
- Black oxide and passivation
- Bead blasting and vibratory polishing
- Laser marking and part serialisation

How it works
From drawing to delivered parts
Upload CAD files
STEP / STP / IGES / Parasolid (.x_t) / SolidWorks (.sldprt) / DXF / PDF — up to 50 MB per file.
Configure your job
Material grade, quantity, tolerance class, finish and any special notes.
Get a fast quote
An instant budget price online, then a firm quote with DFM feedback within one business day.
Production & delivery
Machining, inspection report and shipping — DHL, FedEx or your own forwarder.
The RFQ checklist covers what to send for an accurate quote, and the cost calculator gives a per-part estimate before you request one.
The lead time guide explains which factors move a delivery date, and the machining guides library covers file preparation, tolerances, inspection reports and sourcing.

Precision Parts We Make
From prototype to volume production — every part inspected and shipped with full documentation.
The parts page groups what we machine by part type, starting with brackets and robot end effector components.
Equipment
Inside Our Machine Shop
A quick look at the processes your parts move through.
Replacing tooling on an existing job? The CNC tooling reference decodes insert, screw, Torx wrench and cutter body codes.
Industries
Trusted Across Industries
Six sectors make up most of our order book — each with its own documentation and traceability expectations.
Aerospace
Lightweight structural brackets, housings and fixtures in aluminium and titanium, with full traceability.
Automotive
Jigs, fixtures, prototype powertrain parts and small-batch production components.
Medical Devices
Stainless and titanium components with passivation, deburring and clean-surface requirements.
Robotics
Joint housings, end-effector plates and precision gearbox parts held to tight true position.
Consumer Electronics
Enclosures, heatsinks and internal frames in aluminium, with cosmetic anodised finishes.
Industrial Equipment
Custom machine parts, wear components and replacement spares, one-off or repeat.
Each industry page follows the same structure: typical parts, the materials that fit, the standards that apply and the failure modes that cause scrap.
Why us
Why Engineers Choose TechFoor CNC
A quality management system aligned with ISO 9001:2015, behind every order, not just the big ones.
Mill test certificates shipped with every batch, matched to the heat number.
Every part serialised, inspected and traceable back to its material heat.
Design-for-manufacturing feedback within one business day, with no obligation to order.
