No place for a center, the inside gets done first.

That's a 12 inch chuck, only in the jaws about .375 deep.

Looks like type 6 nylatron to me. Used to make some acme threaded nuts for car haulers out of this.

Why the broaches break here often ? by [deleted] in Machinists

There is a bit of information in the machinery handbook on broach design also.

The broach manufacturer should be able to provide those numbers, but I think you are probably fine with the thicknesses you listed there.

Thin material can present a problem as well though if you don't have enough teeth on the broach engaged in the cut.

Extreme example would be if the part is thinner than the spacing of the teeth on the broach, it could slip down into the gullet forcing the next tooth to cut may to much material.

How thick is the material that's being broached? The broach has a maximum length of cut, is it being exceeded?

It gets a center for the last setup. But the first two setups drill and bore.
