It doesn’t look terribly special, IMO. For instance, unsupported round rails are less than ideal as far as rigidity goes, and rigidity is probably the most important consideration when it comes to milling. Although I’ve heard good things about Kress spindles, I’m guessing that spindle isn’t going to do you many favors with milling metal. I’m guessing the spindle is high-speed, which is good for small bits, so that’s a plus. But small bits take small bites, and using a small bit to mill away a lot of material will take a very long time, especially if rigidity is an issue with the machine. And in the end the surface finishes will probably be terrible. If you want to use larger bits, you’re going to need/want to use slower speeds, which some spindles cannot do. A way to avoid milling away lots of material is to do “slot” cutting. Slot cutting works OK on paper, but it is problematic in a variety of ways. Their commercial doesn’t show any coolant being used - slotting without coolant is a recipe for disaster (and adding coolant to a machine that isn’t designed for it can be disastrous too). Steel will also require slower speeds.
How much is it? How important is the price of the machine in your decision? Is one of the intentions of the training class to use a low-cost machine, possibly with the goal that some of the students will buy a similar one?
Using this machine will probably mean your class will mostly be about working around the limitations of this machine and about hand-finishing metal parts. I can’t remember how much you’ve talked about milling, @jamesdhatch, but it’s not something that most people can pick up in a short amount of time, especially not with the proficiency required to teach it to others. In my opinion, laser-cutting is absolute child’s play in comparison.
I haven’t looked at what small mills are available in a long time, but (despite my ignorance) I’d say the Tormach 440 is probably the smallest/cheapest you’d want to go if you’re looking to do “real” CNC metal machining, and I believe they run around… I don’t know… $8k or so when you add up everything you’re actually going to need.
