Preparing a drawing for a machining inquiry(副本)(副本)

A checklist of drawing, material, quantity and inspection details to include when asking about a custom component.

Start with the part drawing

A dimensioned drawing helps define the component you need. Identify the features that control fit and function, including critical diameters, mounting faces and reference datums.

State the material requirements

Include the material grade and condition where these have been specified. Add any required heat treatment or surface finish. If a requirement is still open, identify it as a point for discussion.

Include quantity and delivery details

State the number of pieces, the delivery destination and the requested date. These details help frame the manufacturing review.

Describe the inspection needs

Identify the dimensions and features that need particular attention. Tell us which inspection records or reports you need so that these can be discussed during drawing review.

Attach the available files

Our inquiry form accepts PDF, STEP, DWG, DXF, IGES, JPG and PNG files. A drawing and the relevant CAD model can help explain the same component from different viewpoints.

Share the available information through the inquiry form, and include any questions that should be resolved before manufacture.
