Re: SBL Magnaturn Retrofit
Hi Troy,
Wow. I've heard that hydraulic servos can be very accurate. I believe it was employed on some early semiconductor manufacturing equipment.
Looking forward to see what you do with it. What's the game plan?
Regards

Hay Tom,
To get it up and running with just a toolpost. And later will tackle the turret.
Lathe will be ballscrew with 750W AC servos directly coupled. Spindle hydraulic motor is replaced with a 5 HP Marathon Black Max motor driven by a TECO-Westinghouse A510 VFD.
And of course... Dynomotion boards. :) KFLOP/Kanalog/Konnect combo.
Got some more pics coming...

Out with the old electronics... Its something to see how tech has changed the graphics card is about the size of a mini atx motherboard. :)

So what are you keeping? The feet? :)
Re: SBL Magnaturn Retrofit

Had to replace the turcite on the saddle(Z axis). It was thin and peeling off. Glued on some new and milled it down with a fly cutter. Stuff machines so easy. Will be getting it hand scrapped also.

Now got ballscrews,servos and spindle motor mounted. This was a tight fit on X axis ballscrew as there was not much room at all for a 1" screw and nut. And got the way lube flow figured out. Now onto mounting some electrical components. :)

Needed some more room for electrical stuff. So made a custom electrical box.

Hi Troy,
I see you kept the fan. Whats the plan for the door to the 3.5inch floppies to be used for? :)

Hay Tom,
Boy.... wish my lathe was as clean as the one in your picture :) The door will eventually have USB ports.

Nice work on the electrical enclosure. I like your welding bench, how its enclosed and storage underneath. Do you have a fume extractor or something up top? I bet it would work really well like that.

Thanks.
No, but there is a big exhaust fan in wall beside it that does the job very well. Now that you mention it i could easily duct to it and use a smaller fan for welding and such :idea:

Here is a video of making the Zaxis Ballscrew nut for lathe. I used Fusion360 for the High Speed Toolpath code and using my Dynomotion retrofitted Hurco mill. :)
