My guess is that they do - but maybe not since they are transitioning to "post configurator" posts. I think there are still siemens employees that make "postbuilder" ones too. These machines have a lot of capability. I would make sure that the post you get is:
1) Forward compatible (is open? require maintenance?)
2) Has all of these capabilities : turn, mill 5 axis, mill prismatic G68, G12.1 polar, XZC mode polar, cylindrical interpolation, on machine probing, lock axis and rotate udes functional.
You would probably be served best by a "kit" with CSE ISV with it (but this may be a little expensive.)
If I were you...
Create your own test parts.
Make sure to test EVERY operation/cut type you want the post to support.
Then make sure the posted output from your part runs crrectly on the machine.
Note (for reference) my test parts are typically:
- Turning: about 20 operations PER TURRET, PER SPINDLE (i.e. 2 turret 2 spindle = 80 operations)
- Milling (5 axis): about 150 operations if table-table. 200+ if tool rotates. Add 50%-100% for 2nd spindle
Production: NX10.0.3.5 MP5 + patch/TC11.2
I'd rather be e-steemed than e-diseaseled
