Milling · turning · 5-axis · grinding · wire EDM
4
Finishing
In-house + global partner network
5
Inspection & delivery
CMM + vision, with documentation
MATERIALS & FINISHES
(Turning and milling typically to ±0.01 mm; grinding and polishing to ±0.005 mm, under controlled conditions. Inch values converted at 1 in = 25.4 mm.)
FAQ
What tolerances can you achieve?
Micron-level tolerances on critical features.
What finishing do you offer?
Clear and hard anodising, electropolishing
Do you machine ceramics and exotic materials?
We machine aluminium, stainless, and technical ceramics such as alumina.
Can you hold high flatness and fine surface finishes?
Yes. Precision grinding and lapping deliver tight flatness and fine finishes on critical surfaces.
Do you machine vacuum-compatible parts?
Yes. Parts are machined and packaged for diverse applications.
CASE STUDY
Process Consolidation
Aluminium Enclosure for Measurement Instruments
Product: A5052 aluminium enclosure (Ø50×30L to Ø150×100L) for measurement instrument cases
Machine: 5-axis machining center + hairline finishing machine
Lot size: 200–500 pcs
Challenge: Complex geometry with hairline surface finish required four separate machining operations in Japan, with high labor cost for the finishing step. Manufacturing cost was excessive.
Result: Aizaki Vietnam’s 5-axis machining center consolidated four operations into two. Hairline finishing was performed in Vietnam at lower labor cost. The client, initially concerned about cosmetic quality on exported parts, was reassured by the Japanese-standard quality management system in place.
