CNC Machining
Custom CNC Machined Parts
Non-standard components machined to your drawings and specifications. We coordinate sourcing, production follow-up, and export delivery from China — minimum order quantity, price, and lead time are confirmed per inquiry.
Machined to Your Requirement, Not from a Catalog
Custom CNC machined parts are components produced against your drawings and specifications rather than standard catalog items. Jinjiuhui coordinates the sourcing and machining of such parts through manufacturing resources in China, covering turning, milling, drilling, and secondary operations as the part requires.
We are a trading and sourcing coordination company, not a factory. Part feasibility, tolerances, surface finish, and achievable dimensions depend on the part itself and the assigned manufacturing resource, and are confirmed with you per inquiry before any order is placed.
Information Needed for a Quotation
A complete requirement lets us confirm a quotation faster. Please prepare the following before submitting the form:
- Product name and intended application
- Material (e.g. aluminum, stainless steel, carbon steel, copper, engineering plastics)
- Quantity (prototype, small batch, or production volume)
- Key dimensions and critical features (a dimension list or drawing reference)
- Required delivery date and destination country
This site does not accept drawing uploads. After you submit the quote form, drawings (PDF, STEP, etc.) can be shared by email or another agreed channel.
Suitable Part Examples
- Shafts, axles, and stepped pins
- Sleeves, bushings, and collars
- Brackets and mounting plates
- Connectors, fittings, and adapters
