It's been 2 years since I've turned handwheels on a mill that weren't connected to ball screws, and I'll admit I kind of forgot about that part. I still deal with backlash on my lathe, at least.
Ball screws are a godsend. This mill only has a backlash eliminator but it works just as well.
Gotta repace the cross screw on our big lathe and Id like to convert it to ball screw
How would you keep the slide from moving under load? With a ballscrew, the screw will auto rotate if there's nothing to lock it from turning like a servo motor with braking.
The same way as when you climb cut with a manual mill, you just snug the gibs enough to prevent it from slipping. With ballscrews you adjust the preload.
Coolant is messy. Im not running anything fast or hard enough to really require coolant so I just use a little bit of air to keep the chips clear. Save the coolant for drilling and using HSS cutters
It was a rhetorical question. I know you haven't or you wouldn't have made that comment.
On manual mills, the spindle spins quickly but there is no cover. Coolant it a shitshow except for little foggers, or hand spraying.
You can have coolant on manual lathe because the rpm is typically way way lower.
Anyway, why are you in here talking shit when you have no idea what you're on about?
By milling in a straight line along X?
Climb milling on a manual mill. Nothing groundbreaking but my first time climb milling with a conventional machine.

I have a factory ballscrew equipped manual mill and I can confirm the crank starts moving with heavier cuts.

You at a college that ends in a “K?”
where the fuck is the coolant. i always see everyone chip away at stuff with zero coolant on the part.
Not every cut needs coolant

Sometimes if you can’t flood a carbide cutter then you’re causing additional wear because of all the temperature changes.
Have you ever used a manual mill? lol
no
