We have sheaves that we inspect from suppliers from time to time and we are in a debate about whether we are using the best method to check them.
We have a fixture, that is quite old, that holds the sheave on a zero spindle with an expanding mandrel and then has two dial indicators with balls on them that we move in to check wobble and hop. The problem is that the error in the fixture is pretty close to the tolerance available. We need to update the fixture and don't know if we should just check them on the CMM, which method do we use, or do we invest in a Runout machine.
I was hoping that someone in this forum has experience in checking sheaves and could lend me a hand.
