heaviest workpieces. Linear glass scales, provid-
ed as standard equipment, have a resolution of
0.000002 inches (2 millionths) and support
absolute positioning. Powerful linear shaft
motors provide a non-contact, zero-wear drive
system that is inherently backlash-free and
ensures accurate table movement.

Perhaps one of the most important features
supporting high levels of accuracy is the

Thermal Buster™ thermal stability system, which
directs chilled dielectric fl uid to key structural
areas to control thermal expansion and ensures
the most accurate positioning possible.

The MV4800-ST includes Mitsubishi’s latest
CNC controller, the M800. This advanced
controller combines an ergonomic design
with sophisticated control technology. The
high-brightness 19” waterproof display tilts and
swivels to achieve optimal positioning for individual operators. In addition to a full keyboard and mouse,
the touchscreen display supports swipe, pinch, and tap operation. M800 CNC Control

The M800 includes Mitsubishi’s new Advance Pendant Box. This compact, handheld pendant has a thin,
tapered design that is easy to grip. It features a large 3.5” color LCD touchscreen that allows operators to
easily access multi-function menus and initiate several alignment and pick-up routines—making setup
quick and easy.

The controller is multitasking, allowing for complete programming and graphical verifi cation of the next job
while the current job is in progress. It also includes onboard CAD/CAM programming, enabling DXF and
IGES CAD fi les to be imported directly for conversion to NC programs.

Mitsubishi also offers a PC version

a machining conditions screen that
enables the proper technology to be
