We finished this up a year or so ago... But thought it might be of some interest.
This is a picture from the manual...
2 of these machines where delivered to a local manufacturer in 1968. They used them until the early 80's at which point they where thrown out. Dad came along to the salvage yard and saw them. They had the manuals still in the control and took them home to study. He liked machining and had enough machine tools to do his projects.. (lathe, mill, shaper, grinder....) After reading the manuals he decided that for the price of steel - that might be a good deal.
We added onto the shop and poured the bases.. (the table and spindle are 2 separate assemblies.)
My Junior summer in highschool in the late 80's was spent splicing thousands of control wires that where cut with a saws-all... Learned a lot . We actually ran with the original 60's control well into the 2000's until it finally died. (and we decided that we where not fixing it any more.) Originally it had hydraulic servos. 2.5 axis and the table rotated (5deg inc) 2 servos - 1 for Y and one for XZ and B.
In came linuxcnc. We found some 80's vintage brushed servos with enough torque to replace the hydraulic ones.. http://electronicsam.com/images/KandT/DSC_0242.JPG We have full 3 axis now Yay.
we went from http://electronicsam.com/images/Kand...on/hyservo.JPG to http://electronicsam.com/images/Kand.../yassembly.JPG and from this http://electronicsam.com/images/Kand...axis/start.JPG to http://electronicsam.com/images/Kand...ervo_mount.jpg
We had converted the spindle from hydraulic to 5hp/VFD in the mid 90's. So that worked great.
We went with mesa hardware. 2 5i20 cards plus 7i48 and 7i33. This gave us 96 i/o and 10 analog axis control. (10 +/-10v outputs and 10 ttl/diff encoder counters.) so true closed loop control. we went from this http://electronicsam.com/images/Kand...rcontrller.JPG to http://electronicsam.com/images/Kand...ctricalbox.jpg
Everything is working again. (plus we have everything that comes with a up to date control. - little things like tool tables and cutter comp ) We added a spindle encoder so we can also do rigid tapping and feed per rev (works nice for boring) Recently I added spindle temp comp. So as the spindle gets hot - the Z axis compensates. I cannot say enough about linuxcnc - everything was done within it. (between its hal and ladder logic)
2 pallets with changers
60 tool chain.
2 inch ball screws through out.
roller bearing ways.
The machine was built like a tank.
