The Haas EC-400PP (Pallet Pool) is a high-volume, 4-axis horizontal machining center (HMC) featuring an integrated multi-station pallet pool designed for automated, unattended "lights-out" manufacturing.
Depending on whether you are looking at the legacy model (pre-2018) or the completely redesigned Next-Gen model (2018–present), some variations apply.
