Verdict
With the same pallet, load and rapids, choose by tooling. The Makino a51nx fits cells that run a family of parts from one magazine: 60 tools as standard and up to 311 as an option, with a 20,000 rpm spindle available. The DN Solutions NHP 4000 fits production of a few part numbers that 40 tools cover, and gives 15,000 rpm as standard and 660 mm (26 in) of Z for deeper tombstone setups.
