Source custom CNC machined metal parts from China with one point of contact for drawing review, manufacturing coordination and delivery. RB TradeBridge works with manufacturing partners in Dongguan to support overseas buyers in robotics, automation and industrial equipment.
CNC milling for custom metal components
CNC milling removes material with rotating cutting tools to produce features such as pockets, slots, holes and mounting faces. Share drawings for brackets, housings, mounting plates or other custom components so we can review the geometry and manufacturing route with the appropriate partner.
For a useful milling review, identify the critical features: mating faces, hole positions, threads, flatness and any surfaces that need a specific finish. Mark the dimensions that affect assembly or function.
CNC turning for shafts and cylindrical parts
CNC turning is suited to rotational features such as diameters, shoulders, grooves, bores and threads. For shafts, sleeves, bushings and similar parts, include the dimensional drawing as well as the model so fits, concentricity and inspection requirements can be discussed before quotation.
Additional processes for your drawing
Our coordinated processes include 5-axis machining, EDM, wire cutting, grinding and surface finishing. The manufacturing route depends on the material, geometry, tolerances and quantity. When a part needs several processes, the sequence and inspection scope are reviewed together.
Material, quantity and inspection requirements
- Material: specify the grade, condition and any material documentation needed. If a substitute is acceptable, tell us before quotation.
- Quantity: state the quantity per part number and whether the inquiry is for a prototype, a first batch or repeat production.
- Finish: identify the finish, cosmetic surfaces, masking areas and any dimensions that apply after finishing.
- Inspection: highlight critical dimensions, datum references and any report or traceability requirements.
We confirm the proposed scope with the manufacturing partner for each project. Tolerance capability, lead time and documentation are assessed against the actual drawing.
How your project moves forward
- Share your requirements. Start with the part description, quantity, material and target delivery date. For confidential drawings, contact us to agree on a sharing method.
- Review the drawing. We identify missing information and discuss the manufacturing and inspection requirements with the partner.
- Review the quotation. Confirm the manufacturing scope, price, lead time and delivery terms before placing an order.
- Coordinate production and delivery. Tim remains your point of contact for agreed project updates and delivery planning.
Frequently asked questions
Are you a factory or a trading company?
RB TradeBridge is operated by Dongguan Runben International Trading Co., Ltd. We coordinate manufacturing through partner factories in Dongguan. Your quotation and order should identify the agreed commercial and manufacturing responsibilities.
Can I request a prototype or small batch?
Include the required quantity per part number in your inquiry. We review prototype and production requirements with the partner and confirm project suitability and commercial terms before quotation.
Do you offer instant online prices?
Quotations are reviewed against your drawing, material, finish, quantity and inspection requirements. We do not provide an automatic price without checking the project scope.
