Mini HMC
Haas Automation Inc. introduced the latest addition to the Mini line – the new Mini HMC. This compact horizontal machining center offers a generous 15" x 15" x 10" (xyz) work cube, a twin pallet changer and built-in 4th axis capabilities. The machine is equipped with a 12,000 RPM, 40-taper spindle that features a unique inline, direct-drive system that couples the motor directly to the spindle rather than using belts. This results in less vibration, less heat and less noise while providing better surface finishes and extreme thermal stability. Powered by a 30 HP vector drive system, the spindle yields plenty of low-end torque as well as the speed necessary for high-speed machining operations.

The twin pallet changer (300 mm pallets) allows the operator to load and unload parts on one pallet while the machine mills parts on the other. Once machining is complete, a servo-driven changer swaps pallets in a mere 2 seconds to maintain nearly constant spindle time. A built-in 4th axis provides precise positioning for multi-sided parts and tombstones, or allows simultaneous 4-axis motion for complex geometries. Ultra-fast ballscrews and high-torque servo motors on all axes provide rapids up to 2,000 ipm and accelerations to 0.75 g to reduce cycle times, and a 24-pocket side-mount tool changer swaps tools in just 2.8 seconds.

While gravity helps clear the chips, there is also plenty of coolant available for any machining operation.
