I put our adapter beside the delivered FR10 package and the interface profile is visibly different from the drawing the seller approved; label suffix differs too, so I've left the tool unfitted while our toolroom asks what exactly is supposed to be equivalent.
Ask for the agreed and delivered configurations compared by identifier and drawing revision, with the effect on your complete tool assessed. Similar-looking bolt holes won't settle the interface.
Toolroom asked for that and the seller sent another front photograph, which is the one view that hides the profile difference; I've sent side views back with the approved drawing marked.
We spent too long discussing whether an offered substitute might work before asking whether they could supply what we'd actually agreed. I'd keep that option on the table, Grace. It needn't be your job to redesign around the delivery.
Chen, yes, provided the replacement offer names the exact configuration. 'We'll send the right adapter' can produce another exciting parcel and the same unresolved question.
They now say they can supply the agreed adapter revision, but have given no availability or delivery date; thank you Chen, I've asked for those without dropping our comparison request.
Have your tooling reviewer confirm the offered adapter matches the delivered interface and full assembly. Supplying one agreed component may not resolve every difference you found.
