Haas EC-400

What the maker publishes about the current Haas EC-400

Haas places the EC-400 among its 40-taper horizontal mills, and the machine works in 4 axes. A pallet changer is part of the base machine and carries 400 mm pallets. Those pallets do not interchange with the ones used by the earlier generation of the EC-400. The fourth axis is a full rotary system, and it supports synchronous motion. Spindle speed is given as 8.1k RPM. The standard side-mount changer has 30+1 positions. As options, the changer grows to 160+1, 100+1 or 50+1 tools. The machine also takes an optional 6-station pallet pool. The present EC-400 is a redesign that Haas calls all-new.

What the Haas EC-400 is used for

Haas aims the EC-400 at large batch runs and unattended machining, with a built-in changer for its 400 mm pallets, and it names a 6-station pallet pool and bigger tool changers as the route to longer lights-out running.

What to check on a Haas EC-400

• Spindle. The manufacturer gives a spindle speed of 8100 rpm. Run the spindle to top speed and listen for bearing noise.
• Spindle load. The manufacturer gives 22.4 kW (30.0 hp) of spindle power and 122.0 Nm @ 2000 rpm (90.0 ft-lbf @ 2000 rpm) of spindle torque. Take a heavy cut and watch the load meter.
• Spindle taper. The manufacturer gives a spindle taper of CT40 | BT40 | HSK-A63. Check it for fretting and that the drawbar holds a tool.
• Axes and way covers. The manufacturer gives X 559 mm (22.00 in), Y 635 mm (25.00 in) and Z 559 mm (22.00 in) of travel. Run each axis end to end and check the way covers.
• Rapids and ballscrews. The manufacturer gives a rapid traverse of 35.6 m/min (1400 ipm). Measure the backlash on each axis.
• Tool changer. The manufacturer gives the tool capacity as 30+1. Cycle every pocket and watch for a hesitation.
• Tool-change time. The manufacturer gives a tool-to-tool time of 2.80 s and a chip-to-chip time of 3.60 s. Time a tool change against that.
