The EC-400PP HMC from Haas Automation expands the company's EC series of HMCs. It has added the integrated, six-station pallet pool tot he EC-400. Designed for high-volume production and untended operation, the machine features a 70-pocket side-mount toolchanger, 1,000 ipm rapids, 300-psi through-spindle coolant, 1 MB of program memory, USB port, remote job handle and a high-volume coolant system. To remove chips quickly, the machine also has an auger-fed, belt-type chip conveyor system.

Each of the 400-mm pallets has a load capacity of as much as 1,000 lbs. The pallets can be scheduled individually according to priority and sequencing requirements, which allows high-priority parts to be machined first and/or staged more often. Completed pallets are returned automatically to the holding location, or can be sequenced to a protected operator station for immediate unloading and re-loading.
