Bridgeport J-series mill convert
Posted: Wed Dec 08, 2021 9:08 pm
Hello members
first, sorry if there is a spelling mistake, as english is not my first language.
this project was not to make a precise machine, but to train me on cnc, cad, cam when I was laid off during the pandemic
I chose Centroid because I had previously read about the A560xl machine, and happened to see that there were retrofit kits for old milling machines that Centroid offered, and why not try to rebuild my machine, just to master CNC with a professional control
I want to share this conversion with you, in the enthusiasm of the thesis, a few pictures were taken, not so many, but those I have I will share with you.
I have a old Bridgeport mill(J-Head)that had worn out spindel bearings and a few more issues as rusty ways and oil-channels full of grease and generaly neglected.
My first task was to disassemble the entire upper end of the mill, clean it and replace all bearings, weld and build up some new worm teeth and give it a coat of paint. I needed to have a functionally head to to complete the conversion.
sorry the first picture is not straight I ordered nema 34 close loop steppers, drivers, ball screws and a VDF from the other side of the globe (cheep )and good enough for this project.
It is the path of learning. Isnt it? I have mostly been uncompromising on other things and projects, but this was just education
An old fuse box was converted into a control cabinet
VFD was scrapped at the moment due to the old elektrical engine, and interference
To be continued
