Machining Services, Prototype to Production
Most parts need metal removed somewhere — and the right machining route controls cost and lead time. P&A International engineers milling, turning, drilling, boring and grinding of standard and complex parts across many machine types in the partner network, in metals and engineering plastics, in low and high volume.
As an engineering-led contract manufacturer founded as an engineering consultancy, we assign one dedicated engineer who advises on design-for-machining, specifies materials and delivers free off-tool samples, then scales into volume through our vetted partner-factory network, where every supplier is ISO 9000 certified or better.

What we deliver
Milling
3-axis and multi-axis milling of prismatic parts, plates, housings and brackets to your drawing.
Turning & lathe work
Turned shafts, pins, bushes and round parts, with live tooling for milled features in one set-up.
Drilling, boring & tapping
Precise holes, bores and threads, including deep-hole and multi-spindle work for volume parts.
Grinding & finishing
Surface and cylindrical grinding for tight tolerances and fine finishes, plus deburring and coating.

Why engineers & buyers choose PA
For design engineers
A true design partner — one dedicated engineer, design-for-machining advice, material specification and tolerance review across milling, turning and grinding. We help reach the tolerance and finish you need without over-machining the cost.
For purchasing
Low-risk scalability — free off-tool samples before mass production, prototype and production both supported, target-cost DFM, a single point of contact, and a vetted ISO 9000+ partner network managed end-to-end by P&A.
3 easy steps to get started
Send us your part
Share a model or drawing with material and quantity — or just the part. One dedicated engineer reviews machinability and quotes.
Proposed approach & quote
You receive a proposed machining approach and indicative pricing — typically within 48 hours — to review and refine together.
Samples & production
Free off-tool samples with quality-assessment reports. On approval, parts are machined, finished, inspected and shipped through our partner network.
Applications
Industrial equipment · automation · electronics & thermal · energy · instrumentation · automotive · prototyping & spares.
Machining is one part of our metal capability. For tight-tolerance and titanium work see our precision CNC machining page; also explore the aluminium & metal hub, metal & steel fabrication, and metal stamping.
Choosing the right machining route
A few early decisions shape every machined part — sharing this detail lets us quote and prototype faster:
| Milling vs turning | Prismatic parts mill; round/shaft parts turn; many parts use both in a mill-turn set-up. |
| Tolerances | Hold tight tolerances only where they matter; grinding handles the tightest and best finishes. |
| Material | Aluminium for cost and weight; steel/stainless for strength — match to the duty. |
| Finish | Specify surface finish only where needed; coatings need the right base material. |
| Volume | Prototype and production pricing differ — share both for the right route. |
What to send us for a fast, accurate quote
The more of this you can share, the quicker we can return a proposed design and price:
- A model (STEP/IGES) and/or a drawing with key dimensions
- Material and any critical tolerances
- Surface-finish needs on key faces
- Prototype quantity and production volume
- Finish and secondary operations
- Target cost and call-off pattern
