The box way glides on a dual-layered oil film, wedge-shaped on the top and laminar on the bottom. The wedge-shape improves sliding the faster the box way moves, which extends the service-life of sliding surfaces under a constant load. Under fluctuating load, the laminar layer acts like a cushion and laterally disperses and dampens the impact force along the slideway.

Coolant cooling unit (separate type) <Consultation is required> OP

Raised coolant temperature causes thermal displacement in the fixtures and workpiece, affecting the machining accuracy of the workpiece. Use this unit to prevent the coolant from heating up. When using oil-based coolant, the coolant temperature can become extremely high even with the standard coolant pump, so please be sure to select this unit.

When using oil-based coolant, please be sure to consult with our sales representative.

●　 While this unit is not the only way to completely control the temperature of the coolant, it makes a major contribution to preventing increases in the oil temperature.

OptionOPHigh-Performance Operating System

Equipped with a USB interface● Data can be transferred easily between the machine and your PC.

(For the USB memory, please use DMG MORI specified products. We cannot guarantee correct operations with other peripheral equipment such as USB hard disks)

A large MAPPS program storage area＊

● We have prepared an area which is separate from the NC memory, where programs can be stored in MAPPS.

MORI-SERVERA network-enabled data management system for high-speed transfer of data between computer and machine.

＊　 Programs can be transferred between the program storage area and an external device such as an NC memory, an RS-232-C connection, a card interface, a USB interface or the MORI-SERVER. Programs that call sub-programs stored in the program storage area using M98/G65 must be stored in the NC memory.

●　 Please see the product catalog for details.●　The photo shown may differ from actual machine.●　Information about the screen is current as of September 2014.

The CPU’s processing power has been improved, with many functions which dramatically reduce the time for programming and setup. The 3rd generation operating system MAPPS Ⅲ is designed for productivity. A new interface connecting person and machine.
