Original Press Release:

Off-Center Y-Axis Cutting Comes to Mazak's Successful Nexus Line With the Quick Turn Nexus 250MSY

The overwhelming response to the Nexus line of CNC turning centers and vertical machining centers by manufacturing customers continues to confirm it as the right response to an economy where manufacturers must have increased machine productivity and reliability through advanced technologies at a reasonable cost.

Now Y-axis cutting has been added for complete multi-tasking machining operations on a Nexus CNC turning center with the introduction of the Quick Turn Nexus 250MSY.

With advanced integral spindle/motor technology, spindle output on the new Quick Turn Nexus 250MSY is 18% higher (35 Hp, 4,000 rpm) on the main turning spindle (10-inch chuck) for heavy-duty metal removal and high-speed cutting of aluminum and other non-ferrous materials. The second spindle has a 6-inch chuck size, 10-Hp output, and 6,000-rpm maximum spindle speed. The additional rotary tool spindle for milling has 7.5 Hp output and 4,500-rpm maximum speed (with 6,000 rpm optional). Rotary tools and turning tools alike can be mounted at any position of the 12-station drum turret, and quick-change toolholders can be loaded or unloaded with a single turn of a wrench.

Production capabilities are greatly expanded with the Nexus QTN-250MSY. A workpiece can be quickly transferred between the first and second headstock to complete machining operations. The workpiece can be automatically oriented in phase for smooth, continuous operation. Rapid traverse in the X axis is 1181 ipm, 826 ipm in Y, and 1299 ipm in Z. High-gain servo control makes acceleration/deceleration fast and virtually vibration-free. Single-step 12-tool position turret indexing time of 0.2 seconds per position minimizes idle time, which increases productivity.

Equip the Nexus QTN-250MSY with an optional bar feeder and you can take advantage of the bar feeder schedule function that comes standard with the Mazatrol Fusion 640T Nexus CNC. Different parts can be scheduled and cut in varying quantities out of the same bar stock. Sets or kits can be produced continuously and automatically. The Mazatrol Fusion Control also allows networking the machines on the production floor (with optional PCMCIA interface).

All this productivity comes with environmental consciousness as well. Grease lubrication instead of way lube on the Nexus cuts lubrication use more than 50%, from 30 liters annually to 14.2. Coolant life also is greatly extended due to the lack of tramp oils in the system.

Another benefit of the Nexus QTN-250MSY is the "Tool Eye" automatic tool presetting arm, part of the machine's standard list of features. Simply bring the tool tip into contact with the Tool Eye, and offset of tool nose position, tool measurement, and data registration are done automatically, ensuring accuracy and reducing setup time. The Tool Eye also updates and constantly monitors tool wear.
