Niigata Machine Techno USA Inc. (Elk Grove Village, IL) expands the HN-5X series of 5-axis simultaneous horizontal machining centers (HMCs) with its largest model to date. Capable of traveling 49.2 inches in the X axis, 48.4 inches in Y and 47.2 inches in Z, the HN80E-5X with Fanuc 30iM controller produces workpieces 49.2 inches in diameter, 39.4 inches high, and weighing 3,300 pounds – 1.65 tons.
Featuring a solid cast iron boxway base, the ultralarge-capacity HMC provides maximum rigidity, stability and accuracy. Guideways consist of a combination of hardened and ground hand-scraped turcite for stability and vibration damping as well as long life. The cross section is thick and wide for maximum machine rigidity. Bifurcated bell-shaped column further increases rigidity and cutting efficiency.
Both ends of the trunnion table are supported by the high-load-type roller BRG and a double-lead worm gear system for low-frequency machining. Optical scale feedback system on the X, Y, and Z axes and inductive scale feedback system on the A and B axes ensure consistent accuracy.
A high-torque, heavy-duty spindle complements the rigid machine frame. The spindle head stock consists of single-piece castings for more powerful milling and greater accuracy than bolt-together spindle heads.
For additional efficiency, the tool magazine is driven by a servo motor for fast and reliable indexing.
Ideal for producing parts for customers in the demanding aircraft, automobile, power generator, mold-and-die, and semiconductor industries.
