Jig Borer precision drill / Mill 3PH 220 / 440V 3 Axis DRO cnc kit

Precision drilling and light milling. Table 16 x 7 with 300 x 199mm travel.

3 Axis DRO with ring and line feature, great for drilling rings of holes. Throat 20cm quill centre to column, up to 4 above the table then 16.5cm to the Z slides.

Full set of collets, largest will fit a 12.7mm drill but with reduced shank Ive drilled up to 30mm diameter in mild steel, (only just). One collet is 1MT for a 1MT Jacobs chuck, included. Auto Z feed with adjustable stop and lever operated clutch so can slip if overstressed.

Vernier dials with adjustable position dials and clamp thumbscrews but these are rather obsoleted with the DRO. Dovetails, gibs and pinch levers on X and Y give a slop free movement, gets a bit tight at the ends but thats to be expected. Backlash 8 thou on X and 2! Nuts are split to adjust backlash.

Leadscrews are imperial, 1/10 inch per revolution dials are 0-100, 1 thou / div. Quill has clamp and is very solid. Spindle bearings are in good condition as far as I can tell and feel solid.

I don't see any problems when milling. Z axis assembly is counterweighted with a chain and sprocket to a counterweight in the column. Dual voltage 220 / 415V 3 phase 3/4HP motor, Made in Scotland. Currently set to 220 for domestic 3ph inverter but easy to swap for industrial units.

No switchgear as I run it directly from the inverter. I made a CNC conversion for this as posted on model-engineer, and video on YT "cnc mill cribbage". This sale is with the steppers and fixture hardware (including a new ballrace for the Y axis) but NO electronics control.

The photos are missing a second large stepper and belt, these will be included but are on another machine currently. Would suit someone who has CNC on other machines and can just hook up the steppers. I used GRBL and cheap 5A drivers. The cnc assembly fits to the machine without any permanent modifications so can be completely reversed to manual as it is now.

Its a little tricky, from memory the auto feed has to be removed and a ballscrew removed from a ballnut but I have a sleve so you dont spill your balls on the floor, no-one wants that. I have a full set of images for the conversion and also two linley manuals in pdf.

A lovely and fondly used very compact but solid machine. If I had the space I would keep it. The old filament light makes the bottom of the z-slides look rusty in the photo they are clean.

A few light drill spots on the table, not mine. Runs alot quiter than my lathe. Can sit on a stool and operate all levers. Done lots of (hobby) aluminium and brass milling and fly cutting on this.

Cut gears with an indexer (the other stepper motor).
