Mazak's Successful Nexus Line Now Features Multi-Tasking Capabilities
(FLORENCE, KY) - First introduced by Mazak at IMTS 2002, the Nexus line of CNC turning centers and vertical machining centers has proven itself the right response to an economy where manufacturers must have increased machine performance and reliability through advanced technologies at a reasonable price. Now the Nexus machines achieve new levels of productivity and value with the introduction of the Nexus QTN-250MS with multi-tasking capabilities.
The Nexus QTN-250MS features advanced integral spindle/motor technology (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. An additional rotary tool spindle has 7.5 Hp output and 4,500 rpm maximum speed. 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-250MS. 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 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-250MS 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).
Another benefit of the Nexus QTN-250MS 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.
Manufactured and assembled in Florence, KY, Nexus machines benefit from Mazak's recent $20 million investment in its own manufacturing operations.
In July 2004, Mazak Corp. celebrates 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.
