Currently i have a very rubbish Chinese bench drill press – despite some modifications, I’ve still got about 0.5mm wobble when the quill is extended. It’s going up the tip.
You don’t necessarily need to be that cavalier with it! There are people around who have converted old small drill presses like that into perfectly acceptable tapping fixtures (assuming that it’s not an enormous one, of course). I have an old SIP one, and that’s almost certainly going to be its final guise, as soon as I’ve sorted out the pillar drill that’s currently in bits, as a replacement.
Would I buy a Chinese mill? It depends. Certainly not from absolute choice, but there are plenty of people around who have accepted the limitations of them, and managed to improve them to the extent that they seem to be perfectly acceptable, at least for model-making. If you just want to buy something that you can use, pretty much out of the box, then forget the Chinese – their quality control leaves an awful lot to be desired. Which is why the reputable suppliers offer a set-up service for them.
My personal experience of Chinese mills is limited to a Warco Major Mill/Drill at work, and this required quite a bit of work on the quill and bearing arrangements before it was even acceptable for milling aluminium, never mind anything harder. They are deceptive; the casting looks like it’s pretty solid, and I was going to tap a couple of holes in the side of it for mounting a chuck key bracket. When I drilled the holes, they were all of 1/8″ thick, so I had to use nuts as well.
I like the look of the Proxxon, but like KWIL says, they don’t exactly represent anything like value for money. You’re sort-of heading off in the other direction from the Chinese. In the approximate Proxxon price range is also the stuff from Wabeco, which looks pretty good – I wouldn’t dismiss this out of hand at all, and there might be something more appropriate there…
You asked what else you might need to get, and I have to say that if you get a mill where the head can be tilted sideways, as at least two of your choices do, one of the most useful things would be the means to get the damn thing perpendicular to the table again. I think that most people would agree that tilting-head mills are very much a mixed blessing – you are unlikely to be tilting it very often, if at all, once you’ve found out just how much hassle it is to get it back to where it was before. Almost invariably it’s easier (and probably more accurate) to tilt the work, rather than the head.
It’s very tempting to buy one of those mill clamping kits that you see advertised all over the place, but with a smallish mill, you will find that many of the kit bits are a tad on the large side, especially when it comes to model-making, and can easily get in the way of cutters. Invariably you end up making your own clamping bits, and it’s worth looking back through MEW for articles about this; there have been several – try Harold Hall’s, for instance.
As for what else you get or need – well, it depends on what you want to make with it. At some stage, a milling vice is useful, and for many tasks, especially on machines without DROs, a rotary or indexable table is useful too.
