HCN 8800-II Horizontal Machining Center

The Nexus horizontal machining center family has expanded with the introduction of the Horizontal Center Nexus 8800-II, offering five models from 15.75" (400mm) to 31.5" (800mm) pallet size. This HMC features a larger work area and longer tool length and axis strokes than the previous model. Maximum work size is 57.09" x 57.09" (1,450mm x 1,450mm) and maximum workpiece weight is 4,850 lb (2,200kg).

The HCN 8800-II's 11.5-ton base and column are extremely rigid in construction and were designed specifically to accommodate these high levels of torque and part weight. The machine's travels are 55.12" (1,400mm) on the X-axis (3.94" longer than the previous model); 47.24" (1,200mm) on the Y (3.94" longer); and 52.17" (1,325mm) on the Z (12.8" longer).

Mazak's standard spindle is a 50hp, 10,000-rpm integral motor spindle with 433ft/lb of torque, or for tougher materials, available is the 50hp, 8,000rpm version with 900ft/lb of torque.

The HCN 8800-II features a 60-tool storage magazine with a maximum tool size of 4.92" (125mm) in diameter and 24.8" (630mm) in length when all pockets are occupied. Without adjacent tools, the spindle and tool changer can handle up to 10.23" (260mm) diameter and 31.5" (800mm) long cutters. Chip-to-chip tool change takes only 5 seconds.

The implementation of linear motion roller guide technology allows HCN 8800-II to deliver a rapid traverse rate of 2,362ipm at 0.5G acceleration.

Energy conservation is promoted by utilizing the machine's standby mode. When the machine is idle for a specific length of time, the control automatically stops the hydraulic unit, spindle chiller, chip conveyor, spiral conveyor, lubrication pump, coolant pump and machining work area light. This can lead to a 70% savings in energy costs when the machine is not operating. The HCN 8800-II uses 45% less air than the machine it replaces and it generates 86.2% less waste lubrication oil using grease lubrication as opposed to oil.

Also on display will be the INTEGREX i-150 multi-tasking center.
