Easimill 12075 built October 1985 ... the rebuild.

Anybody out there interested to know about this?

The Easimill is a Denford conversion of a Taiwanese made T1P manual milling machine which they marketed as a "Viceroy", a manual for that version can be found here:

With some bits deleted or chopped off, the replacement of the acme leadscrews and nuts with ballscrews and nuts, some fabricated brackets, stepper motors and a control system you got, for about £ 9000 in 1985, this:

Mine arrived with me about a month ago and here it is, much to the annoyance of the Boss, awaiting the heavy gang to get it in the shed (AKA workshop), which meant taking off the table and the PNC3 control box to get it through the "Workshop" door. Thanks to Dave, Ian, Brendan and Neil, it is now in residence.

i'm interested, keep the pics coming, i have a couple of Denford Quatros that i'm "improving".

I forgot to mention that the magnetic panel enclosure, flood coolant and mist coolant were taken off at that time.

I hope that this story of my conversion of a 415v 3 phase belt drive head Denford Easimill built in 1985 will be of assistance to others who are contemplating or engaged in a similar project.
The object of this project was to operate the Easimill from a remote computer, running motion control software – Mach3 in my case.
If your machine is single phase and fitted with an inverter or has some of the optional extras fitted you will want further information which I do not have, but you will find the wiring diagrams and other information on this web-site.
I do list the Suppliers and model numbers of new equipment I have used but I have no connection with any of the Companies mentioned, other than as a satisfied customer.
I have but scant knowledge of matters electronic, although I am able to read a circuit diagram and during my working career have assisted Electricians in the building or modification of control panels, so DIN rail, klippon terminals, relays etc are quite familiar to me.
Making the first decision to bin all the 415v 3 phase stuff was easy, as I don’t have that in my workshop but the contactors can be re-used for single phase switching, mine had 24vAC coils, there is a 250v – 24v AC transformer in the enclosure on the back if the machine. The contactors are quite large and as space for me is at a premium, these went.

Hi,
Just joined the forum. Noticed your post and photo. My machine came in one difficult lot. the only item removed was the suds tank.
I converted to a singlee phase motor using the smae supply to powere the stepper motors, also fitting hand wheels to x and y axis. I realised that whe not energised the stepper motors supplied a few volts feed back and an isolator switch was fitted in order to prevent this.
It meant that the z axis motor would be energised when winding the table in either direction, thus giving a lock that would prevent the spindle moving.
This has worked satisfactorily until recently whe a friend asked me to drill a series of hole in two lines. Ideal job for CNC.
Two of the stepper motor drives CD20's did not work. Now having difficulty to get repairs done on a budget.
Do you have any suggestion as to how the CNCside can be modified or simplyfied. I am not electronic friendly although some simple electrical circuits can be interpreted.
Any suggestions please. My machine is a 1986 model no. 27016.

I'd be tempted to save the repair money and replace with modern stepper drives.
google words like "diy cnc stepper uk" "3 amp stepper drive"
and you'll end up finding stuff like this

There are loads of CNC stepper kits and breakout boards for the likes of Mach 3, it's just a case of researching and asking in other forums.

Thanks, Will give that a try
