    Default Still Tripped Up On Spindle Motors

    Hi,

    My homemade milling machine is almost done, and I am not sure about a spindle motor.
    I see myself milling a mixture of metal and hardwood (maple), on a fairly tough 3'x4' gantry mill.

    I would like more bit options for a spindle motor, so it would seem that something with a ER 20 or ER 16 would be good, but I would only have a 110v outlet with the remainder of power for my machine. I don't think I need a whole 2.2kw, the bit and collet options seem like a good thing.

    Is it possible to run a Huanyang 2.2KW ER20 well from 110?
    Can I lower the current so my breakers won't be as tripped up as I am?

    Something like this?

    I still wish I had something that could go slower, as well.

    Any advise and experience is welcome : )

    Thanks,
    BrendaEM

    It's doubtful you will really be able to machine metals (with the possible exception of aluminum) effectively on your home-made gantry mill, so concentrating on a spindle that can cut wood makes most sense. Those Chinese 2.2KW spindles are designed to run on 220v; are you sure there isn't a dryer or stove circuit you can use? Otherwise you're stuck with a regular router, unless you want to rig up your own spindle assembly.

    In theory you could, you wouldn't be able to run at full power (unless you have a 30A 110v plug.. unlikely,) but you'd still be able to get full torque at lower RPM's.

    Awerby, thank for the reply.

    Fortunately, aluminum was what I was looking to mill for metals.

    My home-made gantry mill is pretty stout. The x-axis alone weights around 60 lbs, the Z about 32, the Y about 120. That's not to state that weight makes rigidity, so I have 4 corner braces made from 1/2" aluminum to keep it square. The X-and z rails are excessively thick NHK hardened affairs, with two rows of bearings on each side. The Y axis, has some esoteric low-profile rail.

    Still it comes down to tool diameter and depth of cut, but of which would have to be small compared to something like a G0704, but then again, they say that the G0704 column ain't all that.
