Hey Boys,
I been thinking about taking advantage of Okuma Year End Promos on in stock 2019 machines. Looking at the LB3000MYW Lathe to replace the 2 axis LB15 I currently have. Dealer has either a standard bore with 450mm bed or a big bore with 800mm bed. Most(95%) of the parts I make would be smaller diameter, shorter length (think .25Dia up to about 2" Dia.) and well within the range of a 450mm bed. So the 450Bed with the standard bore would be fine for those parts. Thing is, this would be my only cnc lathe in the shop and I really think it would be nice to have the longer bed for those rare jobs that come up occasionally. There have been a few times I have pushed the Z limits on the LB15 and had to get creative . Question is if I went with the big bore in order to get the longer bed length would it be such a bad fit for the smaller work that I would end up disappointed with my choice? The standard bore gives 2.5" thru spindle with 5000rpm. The BB gives 3" thru spindle with 4200rpm. Oh, one more thing, none of this is high production work. So, I'm not sweatin a few seconds more cycle time per part if the big bore is gonna be a little slower.
Thanks for the input...
