Grizzly: Benchtop Horizontal Mill w/ Vertical Head (G0727)

[Doozer]

Somewhere on youtube, and I can't seem to find it at the moment...
Is a tabletop Planer made by Sieg. It looks so cute.
It is probably a one off or only sold in China.
I wonder if Pappa G has one.

Found this site on the internet http://www.mini-lathe.com/mini_mill/reviews/U1/U1.htm

Thanks for this link.

I looked at the SiegInd site. While I find no reference to the U2, either,
there is an SU1 model whose primary difference is the fitment of a 500W
motor to the SU1 in place of the 350W present on the U1.

It is possible there are some dimensional differences, but maybe this is
just a matter of data entry flaws.

** === U1 ======= **

End mill capacity 16 mm
Face mill capacity 30 mm
Table longitudinal travel(X) 300 mm
Table cross travel(Y) 90 mm
Spindle box travel(Z) 105 mm
Longitudinal milling tilting angle 45°L, 45°R
Spindle taper MT3 or R8
Motor output power 350 W
Spindle speed (Variable speed) 200-2000 rpm
Max. sawing cutter diameter ø63
Table effective size 460x120 mm
Overall size (LxWxH) 594 x 740 x 596 mm
Weight (Net/Gross) 95/115 kg
Packing size (LxWxH) 860x870x700 mm

We have had the SU1 in for testing for a while. We just havn't got around to carrying out any tests yet, as too many other things going on. One of our competitors: AXMINSTER POWER TOOLS is selling the SU1, but we dont know what it performs like as yet.

I happen to notice that Grizzly offers a benchtop horizontal mill that
might be of interest to HSM members working at smaller scales.

Why re-invent the wheel when Armor, Benchmaster, Burke #3 and other small horizontals mills (some with optional vertical heads) have been around for decades?

Gunsmithing also made two absolutely true statements.

Armor, Benchmaster, Burke #3 and other small horizontals mills (some with optional vertical heads) have been around for decades?

Why?

Who are the current distributors for new examples of any of these marques?
How many serviceable used instances are available for someone wanting one today?

Rhetorical.

Rhetorical. my ass.

Many Benchmaster, Armor, Sheldon, Vernon, Atlas and Burke (prob. other makes too!) out there are on the used market.
Have you made an exhaustive search for one? Or is weight limit a prime criteria for selection? A 95 kilo, 200lb. mill isn't going to be very rigid, which is what a horizontal mill needs to be.

[uncle pete]

To be honest, I have to agree with Rosco 100%. Even the Atlas horizontals get a fairly bad user opinion from a few members here. But comparing it's gear reduction, bottom rpm speeds and what actual torque would be available along with the built in power feeds? It would eat that Sieg design without question. Stepping up to one of the other makes he mentioned isn't even a contest. Yeah it takes some searching, but good useable models are still around. Pound for pound, any half decently designed horizontal will always out perform your average vertical mill and with less horse power. The verticals are more versitile and easier to set up the work though. I also don't think that Sieg design has close to enough vertical Z axis clearance to make it even somewhat useable in almost any home shop. They could have done a far better job IMHO.

+1 to what uncle pete and Roscoe said. I was purposely withholding making this argument as IIRC we have had it in the past and I was trying to let a genuine discussion about this machine continue. Personally, I have been tempted to get a small horizontal for quite sometime as in these parts theyre common as dirt on CList by many makers known and unknown, usually for <$500. The reason Im tempted tho is that I actually prefer a horizontal due to lack of ability and rigidity of verticals.

The design of this horizontal strikes me as rather odd due to the vertical head mounting. With it being an attachment to the overarm, one would think it would have a quill which is not evident in the pics. Many larger conventional horizontals have a fairly simple vertical attachment that attaches directly to the horizontal spindle drive, not the overarm, tho at least one Ive seen used the overarm to extend the vertical head outward for extra "reach." Does this machine have a seperate horizontal spindle drive in the column, or is the horizontal part simply like using a vertical mill with a horizontal attachment? If it lacks the horizontal drive, I would personally see this as next to useless in "horizontal" mode.

[Rosco-P]

Grizz website, machine specs. state the horizontal spindle (arbor) diameter is 5/8". Where are you going to find milling cutters for that? Certainly not on Fleabay or Craigslist.

[jkilroy]

Thats more than I paid for my last K&T, there are plenty of used horizontals out there. Actual real milling machines, which that is not, do a little shopping.
