Drawing
2D PDF and, where available, STEP or IGES. Mark critical dimensions, threads, tolerances, and inspection points.
Sourcing custom CNC machined parts in China
We organize drawings and commercial requirements, compare quotations, coordinate samples, and follow approved CNC parts through production and shipment.
Start with the drawing
Information needed for a comparable quotation
Material & finish
Aluminum, stainless, carbon steel, brass, plastics. Anodize, plating, passivation, or as-machined.
Quantity & clock
Prototype quantity, expected batch quantity, destination, and required timing. These affect the suitable manufacturing route and quotation.
CNC milling parts
Prismatic parts, housings, and small production lots from 3-axis and mill-turn drawings. We hold the dimensions you mark as critical and flag anything the drawing leaves open before cutting metal.
- Typical: aluminum and stainless brackets, covers, fixtures, industrial components
- Need from you: STEP + 2D, material, anodize/color if any
- Quotation review: compare process assumptions, tooling, sample lead time, and unit price by quantity
CNC turning & swiss-type parts
Shafts, pins, screws, inserts, and small-diameter parts where concentricity and thread quality matter. Brass and stainless are common RFQs.
- Typical: precision screws, aviation-style pins, brass inserts, turned sleeves
- Need from you: thread spec, material, plating, inspection points
- Order control: keep the approved sample and inspection points attached to the production order
Custom CNC gears & sprockets
Milled gears and sprockets from your tooth profile — not catalog-only SKUs. Send module/DP, tooth count, bore, and material.
- Typical: aluminum sprockets, hardened carbon-steel gears, anodized finishes
- Need from you: gear data table or CAD, heat-treat if required
- Before sampling: collect manufacturability questions before the drawing is released
Fixtures, shaft sleeves, non-standard parts
Fiber fixtures, non-standard shaft sleeves, and one-off industrial parts that do not fit a catalog. These RFQs need the drawing more than a product name.
- Typical: optical/fiber fixtures, custom sleeves, small housings
- Need from you: mating part or photo plus CAD
- Before sampling: confirm datums, mating surfaces, and inspection requirements in writing
FAQ
CNC quoting questions
Can you work from a sample if I have no drawing?
A physical sample or clear photos can help start the discussion, but a controlled drawing is normally required before a firm quotation and production.
Do you quote one-off prototypes?
Yes. Tell us it is a prototype so we price a sample lot, not a production assumption.
What is a complete CNC RFQ?
Drawing, material, quantity, tolerance class, finish, and destination port or Incoterm. Incomplete packs get a checklist back, not a guessed price.
