Grizzly DRO for the G4003G

Dave Short said:
Ron,
The symbol is "Microns". A micron equals 40 millionths of an inch, or .00004".

Keep in mind that the lathe will not be any more accurate with the DRO, even though the readout will read to the ten thousandth......The machine is the limiting factor here.

The machine being the limiting factor is true, though I mostly use old USA iron I have checked spindle run out on 20 year old Enco lathes from Taiwan that had a tenth or less run out. The tolerance spec on a new 4003G is four tenths to almost five when new..

crb: are you sure about your information?
I downloaded the manual and it says the carriage travel is 24", and the cross slide travel is 6.25 inches. The Specification sheet has the same listing.

I canceled the order for the Grizzly DRO and decided on the Easson ES-10, the Grizzly was supposed to be the Easson ES-8. The ES-10 is a newer model and has an aluminum housing, whereas the Grizzly (ES-8) is a couple of years old and has a plastic housing, and costs $76 more.

I know sometimes there are misprints in the manuals. Does anybody know what is the correct information so I can order the right length scales? (I am inclined to go with the web sites manual)

Check this site and ask Steve if you have any questions not answered as he is a helpful person and has the lathe in question. :)
