X-Class Machine Tools Offer Affordability, Rigidity, Stability

DMG/Mori Seiki’s X-Class machine line has been designed as a result user feedback on the company’s popular N Series. In the fall of 2010, the company introduced four X-Class machines at both the IMTS exhibition in the United States and JIMTOF in Japan.

The X-class offers precision, quality and reliability at an affordable price with the flexibility to meet customer needs, the company says. The first aspect of the X-class that differentiates itself from other machines in its category is its rigidity. The X-class machine uses a thick, high-rigidity bed with the X- and Z-axis linear guides in a high position; a spindle with a large-diameter bearing; and a table and pallets with a powerful clamping force. The high-rigidity structure ensures stable machining for heavy-duty cutting.

Measures that have been taken to combat thermal displacement further distinguish the X-class machines from others, says the company. The X-class machines use a heat-symmetrical structure that disperses heat evenly and coolant circulation inside the castings to minimize thermal displacement. In addition, the machines exert active control over thermal displacement to enable high-precision machining.

Additionally, the X-class offers economy in energy saving, as well as compact design. The X-class machines use LED lighting and a hydraulic unit equipped with an accumulator, and are designed to reduce environmental burden and running costs. The total power and lubricating oil consumption have been reduced dramatically compared to other larger models.

The X-class machines is available in a variety of models to accommodate different workpiece sizes, machining operations and automation requirements. Currently, the X-class machines are available in the NLX, NVX, NHX and NTX models. They use the MAPPS IV high-performance operating system and are equipped with extensive programming functions, including the standard automatic conversational programming function. The 3D interference checking function is also incorporated in the X-class multi-axis machine as standard, offering effective protection against interference. In addition, Esprit CAM software enables complex 3D programming.
