METHODS MACHINE TOOLS introduced the Nakamura-Tome JX-250, high-performance multitasking turning center, which offers the largest machining area envelope in its class for high-precision milling and turning of complex parts, along with a novel, twin lower-turret configuration that allows considerable flexibility for complex component manufacturing.
The ATC-style Nakamura JX-250 features the NT Smart Cube Tool Spindle, which Methods described as "the shortest tool spindle on the market today." The 12,000-RPM tool spindle permits maximum part length on the left and right spindles, including when the horizontal tool spindle and lower turrets are in the cut.
The new multitasking machining center provides up to 168 tool stations.
"We are pleased to offer the highly precise and efficient Nakamura JX-250 mill/ turn solution for precision manufacturing in a broad range of industries, including aerospace, medical and automotive," said Sergio Tondato, Nakamura-Tome product manager at Methods Machine Tools, Inc. "The JX-250 is exceptionally productive — allowing maximum part length and performing left and right simultaneous machining.”
The Nakamura JX-250 achieves process accuracy with rigidity due to its horizontal bed design with a wide, low center of gravity and vertical column structure, weighing 55,000 lbs.
NT Thermo Navigator AI technology controls thermal growth during machining and compensates for temperature changes.
The JX-250 features a SmartX PC-based, 19-in. high-resolution color touchscreen, which works in conjunction with the Fanuc 31i-B5 control for a high degree of functionality. A five-axis precision milling software package optimizes five-axis milling.
The JX-250 comes equipped with several Smart features, including the NT Work Navigator that can recognize the coordinates of machine parts with non-round shapes (such as those in forgings and castings) without any additional costs involved. This feature eliminates the need for costly positioning fixtures and clamping devices.
The Advanced NT Nurse System all-in-one software package also is included, providing convenient, easy-to-use support for the operation, programming and production on the JX-250. Critical functionality includes phase recognition (for multitasking); direct chucking, enabling transfer without positioning error; and precise synchronization of the left/right-hand spindles. Additional functions include a load monitor for identifying tool wear/breakage, tool life management, and machine monitoring.
All Nakamura-Tome machines are equipped with a standard, electronic detector safety feature to reduce the impact and force of a machine collision. Should a crash occur, within four milliseconds after the crash, servo motor-feeding direction is reversed and the machine will stop in EMG mode.
