Monarch lathe
I was watching a video featuring the Monarch model 10EE lathe and noticed that the X and Y axis can both be powered at the same time. What application would use this feature?

Cutting a taper.
Re: Monarch lathe
A very specific and not terribly useful taper since you don't have any control, much less fine control, of the feeds independently. Unless there is something I'm missing, I would expect it's just a peculiarity of the design that didn't require independent lock-out rather than actually a feature.

Re: Monarch lathe
Monarch makes (made?) taper attachments.

I expect they are still made, or can be had made, but only lawyers (and their cousins the politicians) can afford them.

Re: Monarch lathe
Yeah, ok, but they wouldn't know what to order, and it doesn't come in gold plate.

Re: Monarch lathe
But it is the ratio of the feeds that controls the taper, since everything is gear-driven and therefor synchonous.BadDog wrote: ↑Tue Jul 10, 2018 5:14 pm A very specific and not terribly useful taper since you don't have any control, much less fine control, of the feeds independently.

However, it turns out that you can't engage the leadscrew and the power crossfeed at once: just the power feeds. There may not be many options after all.
Re: Monarch lathe
Exactly my point. The taper is defined by the ratio of the long feed vs the cross feed with no way to change the ratio. If that happens to be 2:1, then you can turn 2:1 (half angle) tapers, perhaps with the compound for depth of cut, but it's not much use otherwise. Maybe that might produce things convenient for an aesthetic feature, but not likely anything else.

Re: Monarch lathe
Correct. If it generated a 45° angle, it would be quite useful, but it doesn't. It can be used to break edges when the angle isn't critical, however. That was something I did on occasion when I was assigned to an EE. Problem was, pretty much everything was specified (including edge breaks), so I wasn't at liberty to use it much.

Re: Monarch lathe
I don't think it cuts a 45 on mine. Maybe it does. It is certainly not a substitute for the taper attachment. I agree with BadDog that it's not necessarily a "feature", but something that didn't need to be made another way.

Re: Monarch lathe
The ATLAS 12" lathe will also engage both lead-screw and cross-feeds at the same time, but I have never tried it. Might be fun to see the flinders fly.
