More of a Brushless DC motor than a stepper... it's bottom speed is 50RPM.

BLDC:

The Craftex is what Engineman uses:

He has he 9516 model... and he turns amazing work with that and a Taig
lathe and mill.


More the crafstman than the tools me thinks...

I have the LMS with the BLDC - very nice.

The Craftex looks like a Seig. Essentially the same machine as a Harbor
Freight, Mico Mark, Grizzly, and Little Machine Shop (which has a much more
powerful motor than the others.)



Yes, it will run at 20 RPM, but the torque is minimal. If that is a
concern, get the LMS. Or get a 7x14 or 7x16. They all have motors at
least 50 percent more powerful than the 7x10's or 12's. Typically 500 watts
vs. 300 in the Craftex. The LMS uses a stepper motor which is much better
at low RPM's Probably more amenable to CNC'ing, as well



Overall, they are great starter lathes, and capable of reasonable precision.
I have modified mine considerably, and as such, have not yet outgrown it.
While I have not CNC'd mine, I have put a DRO on it.

Hey guys,

I'm about to purchase my first lathe, a mini-lathe, and hoping for a little
guidance. I will be using the lathe for some learning and R&D in my home
shop.

I was initially seeking a 7x12 lathe. However, recently I began looking for
an 8x12 or 8x14 mini-lathe, as I read that they are better (more solid,
accurate, etc.) than the 7x? and 9x? series lathes. I have no clue whether
that's true. I'm finding it hard to find a selection of Canadian suppliers
of 8x? units. So, now I am back to considering the 7x12 once again.

So, a few questions:

1. Is the Craftex CX704 lathe considered a good one in the 7x12 size?

2. When the 7x12 indicates 0-1100 and 0-2500 spindle speeds, can the lathe
actually operate at speeds as low as 20 RPM say? If so, why cannot the 10x22
model do the same (specs indicate low ranges of 100 and 200 RPM)

3. Is the 7x12 easily CNC-able? Any idea of the cost & effort to do so?
(I've already built a CNC machine, so I'm very familiar with the much of the
fundamentals, G-code, stepper, controller, SolidWorks, etc.)

4. Does this seem like a good starting point for somebody just learning to
use a lathe (I'm a professional engineer, 20+yrs experience, love to build
stuff, etc.)?

My limitations are the amount of floor space I wish to dedicate to the lathe
(7x12 seems great in this respect).

Any and all comments would be welcome.

Thank you!

Hi Don,

I've gone from I don't have room for a home lathe to being on the
verge of buying a new Sherline. For what I envision doing, and that I
have more confidence in North American and European products, with a
little bit of a preference to employ people closer to home, its a good
fit.

But like you, I'll let my wife know how thrilled I'll be with this
gift from her :-) That and I'll put in some overtime and find something
for her that she wouldn't have purchased for herself, other than lathe
attachments that is. Hmmm, maybe a milling machine.

Now I have to find a source of working material at a reasonable
price.

BTW, I went to Bramalea Secondary School until 1972, were we had
machine shop in grades 9 and 10.

I bought the Busy Bee CX704 lathe and the DRO kit here in Toronto on
sale at $958 CDN tax included. I have it home and cleaned up but have
not yet installed the DRO kit. I put a large bow on it to remind my
wife that it is a Christmas present from her and not a crazy impulse
purchase on my part.

It looks like a fairly easy learning curve headed my way as I
transition from my elderly Unimat DB200 that has served for 45 years
or so and will continue to do so in a reduced role.

I have made a spot for it to reside in my little shop but lack the
muscle to get it there on my own so I am keeping an eye out for
neighbours that may be attracted to short lived employment in the
moving business with a tot or two of Scotch.

Thanks Roy,

I was thinking of putting off my purchase for now, maybe I should
re-think it. They have a few books of interest, I hope that someone
will continue to offer them at a reasonable price.

Sometimes resisting the impulse buying urge means a missed
opportunity. Its hard to know what to do.

While on the subject of impulse buying, BusyBee Tools, which has a
store in Edmonton (cheaper shipping to Yellowknife from there) > > >
