Mitsui Seiki’s new HU100-TS 100 tilt-spindle 5-axis horizontal machining center is built to handle machining of large, hard-metal workpieces that are better suited for tilt-spindle processing than trunnion table operations. The machine’s fixed table and tilting head arrangement facilitates production of heavier and larger parts and can permit use of shorter, more rigid tooling. The new machine offers high rigidity and accuracy when machining tough materials such as titanium and Inconel that are common in aerospace, power generation and other high-value applications.
The horizontal table of the HU-100TS can accommodate workpieces up to 1,900mm (76") long and 1,250mm (50") in diameter, weighing up to 2,000 kg (4,400 lbs.). X, Y and Z-axis travels are 1,300mm (52"), 1,500mm (60") and 1,400mm (56") respectively, with B-axis rotation of 360˚ and A-axis rotation of -30˚ to +120˚. The machine’s compact 5,530mm (221") x 8,431mm (337") footprint is similar to that of its 4-axis equivalent.
The column width and length/height ratio of the HU100-TS are engineered to maximize stability in heavy machining. The machine’s HSK-A100 taper spindle provides up to 150 kW (201 hp) power and 1508 N-m (1,112 lb-ft) torque. A standard automatic toolchanger has capacity for 60 tools (180 optional), up to 500mm (20") in length. Maximum tool diameter is 125mm (5"); tools stored without adjacent tools can be up to 216mm (8.6") in diameter.
Scott Walker, chairman of Mitsui Seiki USA said, “For aerospace manufacturers and others machining tough alloys, the new HU100-TS offers 5-axis, tilt-spindle flexibility and the automation potential of a horizontal machining center as well as the rigidity, accuracy and reliability of a heavy-duty design.”

- automatic toolchanger
Mechanism typically included in a machining center that, on the appropriate command, removes one cutting tool from the spindle nose and replaces it with another. The changer restores the used tool to the magazine and selects and withdraws the next desired tool from the storage magazine. The changer is controlled by a set of prerecorded/predetermined instructions associated with the part(s) to be produced.
- machining center
CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
Carriage or drum attached to a machining center that holds tools until needed; when a tool is needed, the toolchanger inserts the tool into the machine spindle. See automatic toolchanger.
