Horizontal Center Nexus 5000 features 40 hp, 18,000 rpm spindle as standard equipment. Spindle acceleration reaches 18,000 rpm in 3.8 sec. At 91.7 in. wide, rapid-traverse rates in X, Y, and Z are 2362 ipm, and acceleration is 0.8 G. Maximum workpiece size is 31.5 x 39.4 in. The 400 mm[sup.2] pallet indexes 90[degrees] in 1.5 sec, and 2-pallet changer indexes in 7 sec. Forty tools are standard and 80-, 120-, and 160-tool magazines are optional.

Proven in the marketplace as leading machine tools for improving a manufacturing organization's competitiveness and profitability, the successful line of Nexus CNC turning centers and vertical machining centers from Mazak is being extended with a new 40-taper spindle horizontal machining center, the Horizontal Center Nexus (HCN) 5000.

Designed as a general-purpose horizontal machining center for universal applications, the HCN 5000 is anything but commonplace in its technology, performance, and value. It features a high-speed, 40-HP, 18,000-rpm spindle as standard equipment. Spindle acceleration to reach 18,000 rpm is only 3.8 seconds, making the HCN 5000 a high-production work center. And, at 91.7 inches wide, it is space-efficient, with the lowest machine width in its class.

The HCN 5000 has many more outstanding, high-performance features, with various capacities of tool magazines. Forty tools are standard, and 80-, 120-, and 160-tool magazines are optional. Rapid-traverse rates in X, Y, and Z are 2362 ipm, and acceleration is 0.8G. Maximum workpiece size is a generous 31.5 x 39.4 inches. The 400-mm-square pallet indexes 90 degrees in 1.5 seconds, and the 2-pallet changer indexes in seven seconds.

Like the other Nexus models, the HCN 5000 is designed for ease of maintenance and environmental consideration. In previous models, the entire 771-lb spindle/motor assembly had to be removed to change bearings or springs. On the HCN 5000, only a 132-lb. cartridge needs removing to reach bearings or springs. The stator and other components remain in the headstock.

Sealed grease lubrication in all axes instead of way lube greatly reduces oil consumption and extends coolant life due to no tramp oils in the system. All machine units requiring daily maintenance are centrally located with excellent operator access.

30 Years of Machine Tool Innovation

In 2004, Mazak Corp. celebrated its 30th anniversary at its Florence, KY, complex. In 1968, Mazak opened its first sales office in Long Island, NY, and moved to Greater Cincinnati in 1974. Expanding 12 times since then, the Kentucky manufacturing operation is now fully ISO 9001:2000 certified. The entire Florence campus includes a Lean Manufacturing Facility, National Technology Center, and Optimum Customer Support Center. Also established are Technology Centers in such major market areas as Los Angeles, Houston, Chicago, Atlanta, Hartford, and Mexico. These facilities provide complete customer support in manufacturing solutions, process applications, service, parts, and customer training. Mazak produces more than 30 innovative models of machine tools at its Florence facility. The Nexus series of CNC turning centers and vertical machining centers is the latest and most successful high-performance Mazak machine tools manufactured in the United States.
