Re: Okuma lathe C-acis orientation
When setting up a part we indicate across a flat on the part and calculate that as being C0
hy flast, to indicate much faster, you may use a precision level so to orientate the flat in the horizontal phishical plane, then index the C axis with the angle between the X bed and the horizontal plane ( eq30* ), then start to manualy indicate the flat : at this moment, you should need to adjust only 1-2-a few degress
another way, that may be faster, is by using X axis feed-skip, but i never tried it on an y lathe when y<>0
When we run the part the holes we drill on the on are always shifted about 1/4 degree.
is the live tool coaxial with the spindle ?
This shift varies a bit from part to part.
write down the values, observe the tendency, then, if you wish check the coaxility / kindly
ps : if you wish, i can tell you how to also check the tram, but this is not a must for tools with low diameter
