I have 130 of these to be reworked, from China. This is a forging. I need to machine the 20deg area removing about .020-.030 thou. The areas marked in red are critical.
The carriage is about 42"-48" wide. It has to be machined from underneath as shown. There are heavy arms protruding past the area needing to be machined.
I can do this on the mill, using a 90 deg head.
tilting the head back 20 deg. But now we only have one mill. (the powers that be, decided we didn't need the Bridgeport Series II)
And I'd have to move, and re-clamp a long and slow process. Plus tram the head every time to run another job.
I'm not sure if I could set up a grinder on 4 rails, capturing it. Then using a lead screw to move it, maybe motorizing it?
Suggestions, thoughts?
