lining up of HD lathe
lining up of HD lathe
(OP)
Hi,
i am having problems gitting the alignment right from center to center on a HD lathe which i operate. the tailstock has since been lifted from the lathe bed, and i am wondering if there is any kind of equipment to make the alignment process any easier/quicker.
A previous job which was machined was 3mm oval on the 2500m dia.
any ideas plz

We use equipment from Hamar for all of our machine tool alignment.

Mount the gunsight laser in the 4 jaw chuck, and the mirror on the tailstock.
Fiddle with the alignment of each until the reflected dot is centred on the laser, and the dot at the tailstock is centred on the tailstocks axis.
You'll need to be able to spin the mirror to check that it is square to the tailstock's bore.

Whatever happened to autocollimaters and optical squares/hexagons?
Oh well, must be older than Methusala!
Although, out of round is not alignment problem as previously stated - more likely headstock bearings/crosslide play..

On a lathe of any age the bed will have worn more in areas of high use so unless you want to do this for “every job” a compromise has to be struck, or a very costly rebuild.
Having said that I agree with others this is not likely to cause a 3mm oval.
