Core Business
CNC Machining Services
Custom machined components coordinated from China — CNC turning, CNC milling, and non-standard parts, with production follow-up and export delivery for B2B buyers worldwide.
Custom Machining, Coordinated End to End
Jinjiuhui coordinates CNC machining for custom components: we review your technical requirements, match the part with suitable manufacturing resources, follow up production, coordinate available quality documents, and arrange export delivery from China.
Specific tolerances, surface finishes, maximum part sizes, equipment lists, and daily capacity are not published here because they depend on the part and the assigned manufacturing resource. These details are confirmed per inquiry before you place an order.
Machining Processes

CNC Turning
Rotational parts such as shafts, sleeves, bushings, pins, and threaded components. Suitable for cylindrical geometries and stepped diameters.

CNC Milling
Prismatic and contoured parts such as brackets, blocks, plates, covers, and housings with slots, pockets, and drilled features.

Custom Machined Parts
Non-standard components machined to your drawings, combining turning, milling, drilling, and secondary operations as required.
