Here is some pictures of my small ALDRIN milling machine  (updated pictures on CNC conversion in Photos section)

CNC modification is on its way, will try some simple test arrangments with  size #23 steppers with 3:1 reduction via HTD 5 belts 15mm wide. More detailed pictures from this modification work will be entered here as time goes by....

This machine was built around 1975 by machine designer Per Aldrin here in Sweden (Buzz Aldrin's cousin).
I was working at that time as filmcamera tech at Film AB Rune Ericsson and this was one of the tools I purchased as we needed a small real *universal* milling machine, look at pictures and you see what I mean with *universal*.Recently I had the opportunity to get this machine *back home*  and now it is going to be totally overhauled and CNC modified. There was also some of these built as CNC at that time, one of the what i heard was sold to Hasselblad. Don´t know what really happened to the others but there are still some for sale now and then.

Nice platform, built on what we call a "dentist chair base". You can set your working height by pumping it up to wanted level. I think one of the goals was to have a machine adapted for handicapped.

Square cast iron table with power and electronics on right hand side with manual spindle speed control and also speed control for DC motor driving X/Y and rotation. Picture no: 9 shows this *drive-motor* attached to X axis, below a cap on rotational axis where this motor can be fitted. Very handy to have this motor *cranking* the handwheels.

Left side of table ther is the rotational axis with possibilty to 15° fixed/locked stops and top of that X/Y table with 180x180mm movement. The size of table is 340 x 150 with 3 10mm T-slots. Leadscrews with 4mm pitch (TR4 Ø20mm).
Rear column can be moved in X axis 125mm (X² ??), Z axis movement is approx 300mm on column and Z² can be fine adjusted with 65mm, here the pitch is 1mm. The Y² can be moved 300mm and also rotated 360° vertically at the base on column. Here also 15° fixed positions if needed on the rotation.

Spindle head is also possible to rotate 360°vertically, also here 15° positions apply. The spindle axis has been refitted with new precision contact angular bearings 2 months ago. Collets used on this spindle is ER25 directly on the spindle. Motor is  a DC motor (113V 5000rpm torq 1.7Nm made by Powertron/Contraves).

Overhaul and painting is ongoing for a while, I am in no rush :)
