Old Bridgeport power feed not 6f/8f

Ballscrews have minimal rotation resistance. Acme screws have more resistance.
Using the periphery of an end mill can make the table take off.
Other operations as well but that has been the worst one.

So I have ball screws on my x and y...would I have to cut the lead screw to put on a servo type unit? You guys are saying extensions? I’m confused lol

I can't say for sure.

On my mill, I have a 6F power feed. The design of that uses a truncated lead screw that is coupled to a shaft extension in the power feed. If I ditch the 6F, I would have to use a different shaft extension.

You can see that here in this video:

Thank you for clarifying I didn’t know that.

thanks for the video....I hope that’s how mine is. I can’t imagine having to cut the lead screw for a power feed

Just look up under the table. You should see the coupler if there is one there.
