Niigata HN80D Horizontal Machining Centers from SNK America

The high-powered, ruggedly built Niigata HN80D Horizontal Machining Center from SNK America, Inc. efficiently and reliably machines medium to large parts in a wide range of materials, the company said.

"Featuring traverse rates of 1,181 IPM and feed rates of 592 IPM on heavy-duty box ways, the HN80D quickly machines parts," said a spokesperson. "Full 50 HP cuts are achieved through an advanced two range geared headstock. With only three rotating components, maximum power is transmitted simply and efficiently to the cutting tool. Large diameter ball screws, coupled direct to powerful AC digital servo motors, provide high thrust drilling and allow utilization of the latest tool technologies.

"HN80D spindles are as rigid as they are rapid. A large spindle diameter and a single piece, snout type head design ensures heavier milling capability and greater accuracy as compared to traditional bolt-together type spindle head designs.

"Other features contributing to the sturdy construction, and thereby accurate performance, of the HN80D include heavy-duty box ways with hand-scraped mating members, massive columns and bed type (triangular rib structure) construction. The bed type design provides full support over the entire X-axis travel, eliminating the possibility of overhang weakness. The Y-axis double guide system results in enhanced stability and ensures maximum rigidity and improved contouring capabilities.

"Further contributing to the precise performance of the HN80D is the incorporation of a spindle chiller unit. This unit removes excess heat from the spindle and bearing housing. Oil temperature is controlled by a sensor in the machine base that adjusts the lubricating oil temperature relative to the machine's thermal characteristics. This feature reduces thermal displacement of the spindle and provides consistent accuracy during machining. In addition, the stand-alone ATC of the HN80D does not transfer vibration, or compromise precision, to the spindle during tool selection.

"For exceptional reliability, the spindle bearings of the HN80D are constantly lubricated using an oil injection system. This not only maximizes bearing life, but also minimizes preventative maintenance downtime.

"Other design features of the HN80D include an automatic rotary-type pallet changer, a Fanuc CNC control, a variety of built-in diagnostic features, accessible service points and more."
