Ask them to weigh or calculate the complete tool and part, then provide the centre of gravity and inertia information needed for the manufacturer's load assessment.
15 pointsOne supplier sent a revised total with the fingers included but left out the adapter. I sent the assembly drawing back with every carried item marked. Not a very glamorous planning task, but apparently necessary.
3 pointsIt is necessary. And the geometry matters too; a correct total doesn't tell them where all that weight sits.
13 pointsAre both quotes using the same finger length, or are you comparing two different reaches as well as two prices?
9 pointsWorth checking against the nest access. Short fingers look good in a load table until they cannot reach the job.
7 pointsWho approves a replacement finger later? Put that name on the tooling paperwork too
-1 pointsAnd the approved drawing revision. The next person needs more than a name if the spare in the drawer looks almost right.
8 pointsThey were quoting different finger lengths. We now have one defined access requirement and complete assemblies for each proposal. Our tooling lead owns later changes. The supplier load assessments are still outstanding, so price comparison waits.
