CNC 4th Axis On Our Bridgeport

It has 180,000 positions with very close to zero backlash.

Walter, we should try out cutting some gears with this.

That’s awesome! If you could attach a clamp instead of the round stock, it could have a lot more uses as well.

I am game, what are the specifics for the arbor need to hold the gear blank?

That’s pretty sweet!

As an aside, isn’t a device like this essentially what started Haas?

Atm it is clamped with a quarter inch bolt and washer, not that accurate, but enough for experimentation.

So the stock needs a quarter inch through hole.

Adam, This really isn’t it’s intended purpose, but I would like to consider making one of these axis for this purpose, I would consider using something like this 4 jaw chuck.

Yeah, looks like it wouldn’t be an impossibility to adapt a chuck like that.
