Greetings all.

Relative newb to machining here. I work on primarily aluminum block engines ands cylinder heads. Looking into a CNC Mill for block and head decking, tapping for thread inserts, PCD cylinder boring, and some part fab.

I have a line on a Hurco Hawk 5M for cheap. The machine runs well, but currently the auto speed does not work so back gears for rigid tapping won't work until fixed. Down the line a control retrofit will be in order, but until then would like to get auto speed working.

Anyone still have manuals for these or perhaps experienced this problem?

Thanks,
Jim
