Re: LB15 SPINDLE ORIENTATION
hy until you figure it out about the M19, you could use a shaft into the back of your spindle ( thus into the hydra cilinder hole ) with few hundreds tolerance, with a flange with through holes ( so to screw it to the frontal of the hydra cilinder ), then continue outside the machine, into a classical mechanical divider
this should increase rigidity near the far end of the spindle, and may be enough to cut a few splines
if the mechanical divider has play in it, use it with a divider disc that is in good condition
for splines, you have to align the tool shank concentric with the spindle ( use a coax ), and the insert middle plane coplanar with machine ZX plane ( use a dial ); ding for more infos
also, your machine should be able to feed without rpm, and this may require an interlock
what are the spline dimensions ? however, be carefull, not to trash your machine, because a lathe is not designed for 'rough spline-ing'; if splines are relatively small, consider trying rotary broaching
why not outsource these splines ? kindly
