BEFORE WE QUOTE

What to include in a machining RFQ.

Clear functional requirements help us discuss the machining route and prepare a quotation. Include the following information when it applies to your component.

  1. Geometry & fits

    Identify mating surfaces, critical dimensions, tolerances and datums. Mark the features that control fit and assembly.

  2. Material & condition

    State the material grade and required condition, including heat treatment or surface treatment where specified.

  3. Surface requirements

    Call out surface roughness and finishing requirements on the relevant surfaces.

  4. Inspection & records

    Tell us which inspection records, reports or other acceptance documents you need.

  5. Quantity & delivery

    Include the quantity, destination and requested delivery date so these can be reviewed with the technical requirements.

  6. Drawings & CAD files

    Send a dimensioned drawing and, where available, a CAD model. The inquiry form accepts PDF, STEP, DWG, DXF, IGES, JPG and PNG files.
