Haas Automation to Demonstrate New ED-400 HMC
When Haas Automation, Inc., designed
its new generation of horizontal machining centers, company engineers started
from the ground up to build a machine that meets the needs of today's customers
right out of the box - without requiring them to invest in a lot of added
options. "The performance is built into the machine," said a company
spokesperson.
The new EC-400 HMC from Haas is a T-base horizontal machining center with a work cube of 20" x 20" x 20", a dual pallet changer with 400 mm pallets and a built-in rotary indexer. The EC-400 comes standard with an 8,000-RPM, 40-taper spindle powered by 20-HP vector dual drive system. Also standard are a side-mount tool changer (24+1 tools), 1000-IPM rapids and a high-volume coolant system. The EC-400 is equipped with a triple-auger chip conveyor system that removes chips from the enclosure quickly. A belt-style chip conveyor is also available.
For added performance, a 12,000-RPM spindle powered by a 30-hHP vector dual drive system is available as an option. This spindle provides additional horsepower for heavy cuts, as well as 50% more speed for high-speed machining operations. Both spindles feature an inline, direct-drive system that couples the motor directly to the spindle rather than using belts or gears. On-the-fly wye-delta switching provides low-end torque and a wide constant-horsepower band, without having to stop the spindle to change windings.
The EC-400 comes standard with a pallet indexer that provides 45-degree incremental indexing for multi-sided tombstones. For accurate positioning of multi-faceted parts, a high-precision face-gear indexer with 1-degree indexing is available as an option. A full 4th-axis rotary table is also available for shops requiring simultaneous 4-axis motion, and a 5th axis can be added for complex work.
The servo-driven pallet changer on the EC-400 swaps pallets in just 8 seconds, and each 400 mm pallet has a load capacity of 1,000 lb (660 lb with full 4th axis). A separate load station allows the operator to safely load/unload parts or change fixtures on one pallet while parts are being machined on the other.
The EC-400 comes standard with a side-mount tool changer that holds 24 tools plus one in the spindle. A double-arm gripper swaps tools in just 2.8 seconds. To further reduce cycle times and increase tool capacity, a servo-driven 40-pocket SMTC is available that reduces tool-to-tool times to 1.6 seconds.
