    How do they work manually, given the question to be addressed -

    ?
    You think that's too expensive? You're not a Model Engineer are you? :D

    Wabeco, maybe? I think they list a "CNC-ready" vertical mill already fitted with ballscrews.

    I'm buying an AMAT25LV from Amadeal when they come in stock.
    Was going for the 30LV but can't fit it in yet and the extra rpm on the 25 will suit better. Will replace my X2.
    Converting it with ballscrews and steppers 23/34 size to run off Mach3.
    If all goes well I will move the Seig X2 conversion and use it primarily for drilling. Then in a year or so replace the X2 with the 25LV and buy a 30 to put in it's place. Might try to sell the X2 if I can bring myself to part with it.
    Could do with a lathe really, I want to make new pulleys to bump up the rpm's on both AMAT's. Got a few plans and need a re-jig in the cave.

    Keep me out of trouble for a couple of years I suppose :D
    If I didn't mind gear noise I'd have got a Warco WM18 by now but being where I am I need as quiet as possible.

    . Hi, I am thinking of converting a warco super major, and would be interested in knowing your plans for your conversion. My mill as power on the z axis and x axis, and wonder if I can keep these lead screws in the conversion. Would be glad to hear your views on this. Michael

  5. Hi Michael,
    If these are the lead screws that came with the machine then I would suggest that they are not suitable due the backlash. You would have to check to see if they are a buttress style thread, if so then you to change for ballscrews. The Super Major looks the same as my mill so I can provide some guidance and explain how I converted mine.
    I have converted mine to a 3 phase motor and VFD, kept the gearbox and can get 3000rpm which help with the smaller cutters. I could get more rpm but I don't want to explode the gearbox!
    Do you use CAD, if so what CAD system?
    Regards
    Simon

    Hi, thanks for getting back, yes I do use cad. Solidworks for drawings, fusion 360 or vcurve for g code and mach3 for the machine. I have a large cnc router that I use, but the z axis is very limited so the reason I have the warco. I would be interested in knowing which ball screws you used, what sizes etc, motors you used, in fact all the details. Michael

  7. Hi Terry,
    Send an email to simon.m at cubethree.co.uk and I'll send over my CAD in SW2018. I'll also dig out some images of the machining of the casting for the leadscrews.

  8. I used a Bridgeport to machine all in one go the ballscrew mounting features. Used a 90 head to do the end faces. Although a slightly more complicated setup it got everything square and true as best I could.

    I converted my Sieg 2.7 to CNC and I am happy with it.

    What can I say, it's Chinese, so you will need to adjust and improve a couple of things here and there, but nothing major, or difficult. I had to grind a bit of the underside of the table to be able to fit the ballscrew, but other than that it was a straight forward conversion. I read this forum extensively to get me acquainted with what drives to get, steppers, etc. and eventually I made my own toroidal PSU as per instructions in this helpful forum.

    Don't expect super fast speeds or large widths of cut, it's a small mill after all, but if you are sensible, you can have a nice machine that you will enjoy.
    The main negative is that the head is fixed, i'e, it doen't swivel or tilt forward or backward, so for tramming you need to shim the base of the column which requires a little more patience, but quite doable. If you were to get this mill, get the version with the longer table.

    I've only just finished my AMAT25. Hopefully start testing it out this week, time permitting.
