Conect (sic) mill

[IanH]

Help! Has anyone any information on the UK schools' mill from CONECT. I have been given one and replaced the stepper drivers and it works but I would like to know which company built the mill for CONECT.

I've seen a number of lathes labeled under that brand name, and they just looked to be CNC converted Myford lathes of a pretty old style, and mounted in a steel enclosure. D&M was another brand name on some of the same units. Don't know how that ties in though. Hope that gives you a bit of a start at least.

Never seen a Conect mill however, don't know what it would look like or what maker it originally came from. Maybe if you post a pic someone will recognize it.

I will post a photo as soon as I have time and finished current task.

boxford made some of this stuff i think

Here is the machine, in all it's glory. Anyone recognise the manufacturer.

is that a servo motor driving the spindle..if so, how's it run? I have a small servo motor and would love to run have it run a little boley lathe, any ideas?

and is the plate on the conect mill a inf plate?

[The Blight]

Thats a beautfil lathe you have there. And it also looks like a servo motor, but I don't know what type of encoder that is.

We have several boley lathes at work, and I just love seing those old machines doing their thing.

You didn't say what voltage it is? I would guess 60~80 v?
Otherwise for 90vdc, you can use one of the KB/Baldor scr drives, right off the 120vac line.
I would even suspect they will run at lower AC in if a step down transformer was used.
If much lower, get one of the AMC or Copley servo drives off ebay.
It appears not to have a tach, so it may not run as well in open loop as a velocity mode.

Hi
The motor is a DC motor. the rating plate says:- 130v, 37A, 4000rpm

It's UK 230-240 volt AC

130v at 37a is a 4kw (~6.5hp) motor? Sure its not 3.7A?
It sure doesn't look THAT big.
From the apparent size in the pic. I would think that 37a is the demagnetization point, not the stall torque current.

Hi

I keep checking the plate and it says 37A and the digit spacing doesn't appear to leave space for a missing decimal point. It is a SEM 'Ferrite Brushed DC Servomotor'.

hi Ian,

I have been searching the forum for threads on the conect minor mill and found yours. Did you find any more info? I am awaiting mine to be delivered at the moment but i am expecting to have to convert it to run off mach, it is coming without any pc/software you see. Have you had to do the same?
The only thing i have found so far is that the company maker is called Conect Numerical Controls Ltd. Thats all i have at the moment.
Mine does look the same as yours except it is in an enclosed box.

Any info would be appreciated.
Thanks
