To provide an accurate quotation, we need your engineering drawings (2D PDF or DXF) and, if available, your 3D CAD model (STEP or IGES format). Please also include the required material grade, key dimensional tolerances, surface finish requirements, and the quantity needed (prototype, small batch, or production volume).

The more detail you provide upfront, the faster and more accurate our quote will be. If your drawing is not yet finalized, a preliminary inquiry with approximate requirements is also welcome.

Our standard dimensional tolerance for CNC milled parts is ±0.05 mm. For precision-critical features, we can achieve tolerances down to ±0.01 mm. Geometric tolerances such as flatness, parallelism, and positional accuracy can also be maintained to tight specifications, depending on part geometry and material.

Please specify all critical tolerances directly on your drawing. For features without explicit tolerance callouts, we apply standard general tolerances (ISO 2768-m or equivalent) unless otherwise agreed.

Lead time depends on part complexity, quantity, and material availability. For prototype orders (1–5 pieces), we typically deliver within 5–10 business days. Small production batches (10–100 pieces) generally require 10–18 business days. Larger production quantities are quoted with confirmed lead times based on current scheduling.

Rush orders can be accommodated in some cases — please mention your required delivery date in your inquiry and we will advise on feasibility.

Aluminum 6061-T6 is the most common recommendation for general-purpose CNC milled parts due to its excellent machinability, light weight, and good corrosion resistance. For higher strength applications, 7075-T6 or stainless steel 304/316 are preferred. For tooling and mold components, D2 or H13 tool steel is standard.

If you are uncertain about material selection, share your application requirements (load conditions, environment, temperature, weight constraints) and we can advise on the most suitable option.

Yes. We offer both CNC milling and CNC turning in-house, so parts requiring a combination of turned and milled features can be handled as a single order without outsourcing. This simplifies procurement, reduces lead time, and helps maintain consistent quality across all features of the part.

If your project includes both milled and turned components, please send all drawings together and we will provide a combined quotation.

Yes. We offer a range of secondary finishing operations including deburring, surface grinding, anodizing (clear and color), black oxide, electroless nickel plating, and sandblasting. Not all finishes are performed in-house — some are coordinated through qualified local finishing suppliers. Please specify your required finish in your inquiry so we can include it in the quotation.
