RE: [CAD_CAM_EDM_DRO] Re: Monarch 10EE lathe

To whoever was looking for one of these, I've got a line on an older 10ee
with a Dro, a couple of Chucks, toolpost, a steady rest, on a cabinet, with
a three-phase on it. It's in pretty good shape. I'm thinking the guy wants
around $3k for it. I'll find out more. E-mail me off-list if you are
interested.

P.s. Sorry for the Spam
p.s.s. It's in Columbus OH.

The Monarch has two V belts driving the spindle, as does my Tree CNC lathe.
The Tree is direct drive and the Monarch has a two speed gear box on the
motor so the Monarch can produce more torque at low speeds. I'm not sure if
the belts would slip or the motor would stall first on the Monarch. I
haven't had a problem with either, but then I don't usually push it really
hard either.

I was assuming that you are talking about 0.100 on the diameter. I don't
think this would be a problem. Taking 0.100 on the radius might run it out
of power (or slip the belts) though. I've taken cuts like that on my gear
head Monarch just to try it, but wouldn't do it as a frequent thing.

Thanks,

Ward M.

#)Marcus,

#)FWIW, I don't think either of my 5hp CNC lathes would do that cut.
#)
#)The 10EE is a belt drive machine so I'd guess that at that diameter
#)it may not have enough belt "traction". At 450sfm cutting speed, the
#)spindle rpm would be about 575. Pretty slow to transmit much torque
#)without a gearhead.
#)
#)Incidently, Machinery's Handbook has a section on estimating
#)horespower for various machining operations. To use their info you
#)would have to know the approximate hardness of your material.
