M70V Series
Global standard Mitsubishi CNC pursuing high speed and accuracy
The minimum command unit of 0.1µm and minimum internal interpolation unit of 1nm allow highly accurate and smooth machining
High-speed error compensation function is incorporated in spindle and servo controls, which enables high-speed and high-
accuracy tapping, etc
The high-speed PLC engine enhances the operation speed, contributing to cycle time reduction
Enhanced Machining Accuracy and Reduced Tact Time
This CNC is equipped with pop-up screens that prevent operators from being bothered with screen hierarchy, and guiding func-
tion that displays guidance on operations, programs and alarms
Ethernet interface is installed as standard; thus, program management can be easily realized
A compact flash installed in front of the display allows storing of large-capacity NC programs and easy management of mainte-
nance data
Simple programming functions NAVI MILL and NAVI LATHE are installed
Easy and Advanced Operation Contributing to Setup Time Reduction
Unit dimensions have been downsized by integrating a display with CNC control part, contributing to downsizing of control panel
High visibility TFT color LCD is used. 8.4-type and 10.4-type displays are available

Specifications

G code format is available for hobbing.
A spur gear can be machined by synchronously rotating
the hob axis and the workpiece axis in a constant ratio. A
heli-cal gear can be machined by compensating the
workpiece axis according to the gear torsion angle for the
Z axis movement.
Hobbing
(Lathe System)
The control axes of each part system can be exchanged
using a program command. This enables the axis defined as
the axis of the 1st part system to be operated as the axis of
the 2nd part system.
Mixed Control(cross axis control)
(Lathe System)
This function converts the commands programmed for the
orthogonal coordinate axes into linear axis movements
(tool movements) and rotary axis movements (workpiece
rotation) to control the contours.
It is useful for tasks such as cutting linear cutouts on the
outside diameter of the workpiece and grinding
camshafts.
Polar Coordinate Interpolation
(Lathe System)
The added 3D solid model check function allows more
realistic cutting check.
Rapid traverse acceleration/deceleration is performed
according to the motor’s torque characteristics.
As the motor’s characteristics can be utilized optimally,
positioning time is reduced, and cycle time is improved.

By judging shapes in large from commanded paths, unneces-
sary deceleration is reduced even when fine steps exist; there-
by, realizing smooth and deviation free die-mold machining.
Machining time can be shorter by 5 to 30% relative to our
conventional system, especially more effective at a higher
feed rate.
