I need to replace my screws the x axis is 57'' overall the pitch is 4 and it was 1 inch in dia. The y axis is 37'' overall the pitch is also 4 and 1 inch in dia. The mill is a ycm 16 vs 3hp. With Anilam retrofit cnc package 1100s controls. I would like to get a high precision ground screw that I could just slide in and rebolt everything back together. Does anyone have a solution? would greatly appreciate any info.
