A 5‑axis main spind­le and three addi­tio­nal mil­ling units on the same sup­port – this dis­tri­bu­tes the work in stair­ca­se con­s­truc­tion to spe­ci­fi­cal­ly desi­gned units, redu­ces tool chan­ge times and saves a total of 20 per­cent time. Like the gim­bal-moun­ted 5‑axis main spind­le, the units are moun­ted on the Y‑support.
