Nakamura-Tome JX-250 Multitasking Turn-Mill Provides Large Work Area
The Nakamura-Tome JX-250 multitasking turning center from Methods Machine Tools provides a large work area for milling and turning of complex parts. The Twin lower turret configuration adds to the machine’s flexibility for complex part manufacturing. The machine features an automatic toolchanger and the 12,000-rpm NT Smart Cube tool spindle. The short spindle is said to allow for maximal part length on the left and right turning spindles, even when the horizontal tool spindle and lower turrets are in the cut, the company says.
To optimize part transfer, independent right spindle guideways on the lower turrets minimize the distance between the spindles at 11.8" (300 mm). A single or twin lower turret design is offered with overlapping travels and Y-axis box guideways.
The 55,000-lb horizontal bed’s low center of gravity and vertical column structure promote high machining accuracy. The NT Thermo Navigator AI controls thermal growth during machining and compensates for temperature changes.
The JX-250 has a maximum turning diameter of 12.6" (320 mm) and a maximum turning length of 65" (1,650mm). The left and right spindles have bar capacities of 3" (80-mm) and 2.5" (65-mm), respectively. The tool spindle’s X-, Y- and Z-axis travels measure 25.4" × ±4.9" × ±32.5" (645 × ±125 × ±825 mm). The B-axis tool spindle positioning range is 240 degrees.
A SmartX PC-based 19" high-resolution color touch screen works in conjunction with the FANUC 31i-B5 control for programming and control functionality.
Form tools are traditionally associated with non-CNC machines, but in certain applications they make sense on modern machines as well.
Once seen as a specialty machine tool, the CNC Swiss-type is increasingly being used in shops that are full of more conventional CNC machines. For the newcomer to Swiss-type machining, here is what the learning curve is like.
This complex milling operation is performed effectively on a machine that does turning.
