Precision machining in China — the right process, not just the nearest machine
Milling, turning, EDM, grinding: most parts can be made several ways, and the wrong choice taxes every batch. P&A International engineers select the machining route part by part, then place the work with the vetted partner shop best equipped for it — every supplier ISO 9000 certified or better.
One dedicated engineer owns your drawing pack, inspection plan and delivery — whether the part needs one process or four.

Machining processes we manage
CNC milling & turning
The workhorses — 3- to 5-axis milling and mill-turn for prismatic and rotational parts.
Wire & sinker EDM
Hardened steels, sharp internal corners, fine slots and tooling details conventional cutters cannot reach.
Grinding & honing
Flatness, parallelism and bore finishes beyond milled tolerance — for seal faces and bearing fits.
Finishing & assembly
Anodise, plate, heat treat and laser mark — parts arrive finished, marked and kitted.
Send the part, not a process: the quote states which route wins on your tolerances and volumes, and why.
Engineering capability
- Process selection engineering: milling vs turning vs EDM vs grinding, costed at quote stage
- Multi-process parts coordinated under one drawing pack and one inspection plan
- Hardened-steel work: EDM and jig grinding after heat treatment
- Tight-tolerance bores and faces: honing, lapping and grinding to specification
- Heat treatment, anodising, plating and coating routes managed in-network
- CMM inspection with reports; gauge R&R for recurring critical dimensions
- Batch logistics: kanban-style standing orders for repeat machined parts

Why engineers & buyers choose PA
For design engineers
You get a process argument, not a price guess: where grinding beats milling, where EDM saves a redesign, where relaxing one tolerance halves the cost. That conversation happens at quote stage, with numbers.
For purchasing
Multi-process parts usually mean multi-vendor chaos. Here they mean one engineer, one quality file, one delivery — at partner shops you did not have to audit, because every one is ISO 9000 certified or better.
3 easy steps to get started
Send the part
Drawing + model + the tolerance that worries you. Process preference optional.
Route + quote
Process selection with reasoning, itemised pricing, inspection plan.
Proof, then production
First articles with CMM evidence; repeat batches on standing schedule if you want them.
Applications
Precision machined work across industrial automation, hydraulics and pneumatics, tooling and mold components, instrumentation, energy equipment and medical hardware — including hardened wear parts, sealing components and bearing-fit housings.

Which machining process fits?
Rules of thumb our engineers apply (then verify against your drawing):
| CNC milling | Prismatic parts, pockets, housings — the default for most geometry |
| CNC turning | Rotational parts; mill-turn when they also need flats and holes |
| Wire / sinker EDM | Hardened steel, sharp internal corners, deep thin slots |
| Grinding / honing | Flatness, parallelism, bore finish beyond milled capability |
What to send us for a fast, accurate quote
The more of this you can share, the quicker we can return a proposed machining route and price:
- Drawing with datums, tolerances and surface finishes
- 3D model (STEP/IGES)
- Material and hardness state (pre/post heat treat)
- Quantities and repeat-batch expectations
- The dimensions that absolutely must hold
If the part is currently made elsewhere, say what fails — tolerance drift, finish, lead time — and the route proposal will target it.
