We worked this out, the solution was to run a profile cut on all the jaws we ever put in the machine. This way we can run the stick parting tool .800" closer to the holder, and get the rigidity we need. It seems the parting holder for the package could be tremendously improved by making it left spindle side, with the 3/4" pocket coincident the right sub side of the tool, making it wedge type for better rigidity, and taking the coolant ball step and cutting that flat to the base of the holder. At that point the Lynx would be like every other CNC turning machine we have in that regard- not requiring a jaw turn for a rigid parting settup and operation to occur.
We put the 3mm groove tool into a half index holder so we could shorten it up, and that got it cutting ok.
The Lynx could also drastically benefit from a recessed pocket for long drills, and a 6" sub chuck. Our 2100SYII has such a pocket but it is only 3" deep and should be more like 6" deep for optimal versatility. We outfitted our Lynx with a 6" subchuck- we've found those to close jaws much more perpendicular (not angular like the ****ty hobby 5" B205 chuck which doesn't belong in industry CNC machine). With those 3 changes, and some puma like clearance on the sub side of the turret for a conventional main/sub reversible live tool without 2 different style tools required, the Lynx could really deliver all the value Doosan markets it as having.
The first settup on this machine was 12 days, probably half of that was employee under-performance and the other half was relocating the part basket and chute, and figuring out how to get parting tools over a BB206 chuck and cut rigid. Figuring out the C axis brake can only be adjusted manually in the low clamp mode, and that it needs to be between 5 and 7.5 bar pressure to work properly was another development. We also had to plumb a braided line between two holes on the half index holder to get upper coolant to work in a half index mode. We're using Y axis turning and some crazier holders and that had a learning curve. The TT has an A axis, and the Lynx and 2100 a B, Also spindle address commands are different- that's confusing unneccessarily- that axis and those spindles have the same function and those values should be the same. Lots of little quirks in the Lynx. I think the Puma will be easy to work with compared.
