Micro-Mark has a different scale on the feeds, but if you go with a digital readout, it doesn't make a difference.

This unit if done well can do the job but requires some expertise in trade know how or a good new fresh engineer.

As noted by a previous reviewer, this same model (all made by Sieg in China) are available from a variety of sources. I purchased mine from Grizzly, largely because of the support that Grizzly provides. If I were to purchase this same milling machine again, I would probably go with Micro-Mark which is about the same price. The big difference is that the Grizzly version uses 0.060"/turn on the x and y axis and 0.0625"/turn on the Z-axis, while the Micro-Mark uses 0.050"/turn on all axis. It's a lot easier to dial in, say a 0.384 movement at 0.050"/turn than it is to divide 0.0625 into 0.384 to determine the number of full turns and the add'l thousands needed to hit 0.384 exactly.

Anyone considering a small milling machine probably knows that you'll spend nearly as much on tooling as the initial purchase price of the mill. With this mill, plan on additional purchases of a belt drive kit ($120)to replace the noisey, failure prone gear train and an air spring kit ($40)to replace the cheesey torsion spring mechanism. Without the air spring kit, the mill head will occasionally drop 50 thou or so, resulting in an undesired gouge in your work piece. Both kits are available from LittleMachineShop.com (an Amazon supplier).

Provided that you don't push it too hard, this little guy will handle machining of small steel, brass, aluminum, delrin, etc. work pieces with accuracy of +/- a few thou. To do that, however, plan on investing a considerable amount of time on tuning the machine by polishing and adjusting the gibbs and tweaking the nuts on the lead screws to minimize backlash. Besides improving the performance of the machine, this tuning will improve your understanding of how all the pieces fit together to perform the milling function.

I bought mine from Harbor Freight, an attractive option if there is a store nearby. None of these mills are ready to run out of the box, a considerable amount of cleaning and fine tuning is needed first. However, someone who is interested enough in the intricacies of machining will not find these tasks much of a problem. The Harbor Freight mill has the annoying 0.060"/turn axis, but I solved that with a Sumatech digital readout kit. Another good economical choice in DRO's is Yadro. To save even more, just mount cheap digital calipers to the axis and read them directly. The bottom line is that you will spend at least as much as you did on the mill outfitting it with bits, vises, clamps, and useful improvements like the gas spring and belt drive modifications. However, once you've spent about $1,000, you will have a capable and accurate little machine shop on your workbench. For a small machine, it is surprisingly powerful. I've cut difficult to machine materials like stainless steel on it, breaking a few bits in the process but so far no parts of the machine itself.

A few companies sell basically this same machine in the United States. I myself bought one from Harbor Freight, and it is an OK machine within its limits. The thing about the Grizzly version is it has an MT3 spindle taper, which is basically a drill press taper, instead of the R-8 taper that most other companies in the United States offer. R-8 is not a world standard by any means, but here in the US it is by far the standard spindle taper for "small" (as in Bridgeport size on down) vertical milling machines. Why Grizzly continues to offer their machine with the odd taper is beyond me. If you buy the Grizzly version, spindle tooling will be somewhat harder to find, probably more expensive, and if you upgrade to virtually any larger mill later on you will have to buy it all over again. Also the MT3 taper, in drill presses, normally does not use a drawbar whereas R-8 always uses a drawbar. For this reason MT3 has a more gradual taper so the tool wedges and does not drop out. What this means in milling machine use is that the MT3 taper tools wedge tighter in the spindle and are harder to eject when you want to eject them than R-8 taper tools.

I can understand Grizzly maybe offers better customer service on many machines. But all the parts of this particular machine are readily and cheaply available from LittleMachineShop.com anyway, so unless it is initially defective I see no big advantage. And HF has come through for me on customer service for defective items in the past, though they sure don't seem to emphasize service much on their site or in their catalogs. LMS is actually recommended by the Chinese manufacturer of these machines as a world-wide service parts supplier, by the way.

Got mine up and running in about three hours from delivery. Manageable with a two wheeler and a belt. I was able to get it on my table without help from the two wheeler, using the table as a pivot. I have a larger lathe mill and got this as an excuse for a more precision drill press, then started to look at it for a mill. My major issue is the chuck was not as concentric as needed, and tends to drive one side of the cutters harder, making a hard to soft noise. Switching out the chuck seemed to smooth out the process, so I substituted another chuck which works better. I have most of the tooling and like the MT3 set up because it matches my other machine. My big MT3 machine btw has my collet holder captive! Giving credence to the R8 comment, but my other machine holds everything from 1/8 to 1", so is fine. It takes some force on this one to pop the draw bar, I am using a 16oz brass hammer. I made a couple of replacement x and z knobs to steady the table. The long slide stop hit my vise and a circular knurled knob seems to work better with less torque. The table is very narrow, so get a small footprint vise etc. Finish with sharp cutters and light feeds is very nice. The variable speed is great to use. Noise is moderate with the stock gear package. Numerous after market upgrades are available from other vendors, I am evaluating one now. For layout work this is a base machine, if you add DRO and auto feed, it could be a money maker. Cast and hardened and ground parts are shop quality, and controls feel precise, but with plenty of backlash, so always approach from the same direction. I tried some light climb milling in aluminum, and didn't get any problems. I had the cutter stall at slow speed at a breakthrough point, which beats breaking a plastic gear a bunch.Read more ›
