What makes a sheet metal component precision rather than standard?

Precision in sheet metal is not one tolerance applied to a whole part. It is a small number of critical dimensions, usually mounting hole positions, mating faces and overall envelope, held tighter than the general tolerance while everything else stays at standard. Treating a whole part as precision multiplies cost without improving fit. The practical approach is for the drawing to identify which features are critical and what the functional requirement is, so process route and inspection can be planned around those features specifically. YBT quotes against a drawing that marks critical dimensions and inspects those features against the drawing before production release and during the run rather than only at final. Stamped features are held to ±0.05 mm and laser-cut profiles to ±0.1 mm.

Questions you may have

Do you provide a first-article inspection report?

Critical dimensions marked on the drawing are measured before production release and the results are supplied on request. If your purchasing system requires a specific report layout, send the template with the drawing and it is used as the reporting format.

What tolerance can you actually hold?

±0.05 mm on stamped features and ±0.1 mm on laser-cut profiles. Tolerances on bends and assembled dimensions depend on geometry and are confirmed against the drawing at quotation rather than quoted as one blanket figure.

Do you measure with a CMM?

Dimensional inspection is carried out with conventional measuring equipment against the drawing; YBT does not list a CMM among its inspection equipment. Where a CMM report is a contractual requirement, say so at enquiry and it is arranged through an accredited laboratory.

Can you work to our inspection plan?

Yes. Send the inspection plan with the drawing so the critical dimensions and sampling are agreed before production.
