■ Distance to the spindle center
531 mm
(20.9 in.)
The machine has a shorter
distance to the spindle center
and a lower height of the spindle
large nose and front cover rail
to allow easy operations.
■　Height of the front

■　Height of the
spindle large nose
856 mm (33.7 in.)
The hinge type covers are adopted on the both sides of machine.
Large sheet metal used for the machine leg is divided into smaller parts.
This facilitates handling of sheet metal and improves maintainability.
Right side:　X-axis servo motor, ball screws, etc.
Left side :　Gatefold doors allows easy access to the ball screw support bearing,
the sensor for the tool presetter, etc.
Sheet metals at both sides
can be easily opened/
closed by hinges

MAPPS Ⅳ
High-Performance Operating System
for CNC Lathes
High-performance operating system that pursues ease of use, and combines the best
hardware in the industry with the advanced application/network systems.
▶　Outstanding operability thanks to upgraded hardware
▶　New functions for easier setup and maintenance
▶　In the event of trouble, DMG MORI’s remote maintenance
service solves it smoothly
MORI-NET Global Edition Advance OP
Outstanding operability
Vertical soft-keys
The vertical soft-keys can be used as option buttons or
shortcut keys to which you can assign your desired
screens and functions, allowing you to quickly display
the screen you want.
Keyboard
●
10.4-inch operation panel
A PC-type keyboard is used as standard, making key
input easy.
Program management
DNC operation using external memory (front USB port)
Improved ease of setup
OP
DNC operation can be performed using programs stored in an external
memory (USB). It is also possible to transfer data between an external
memory and the NC memory and delete/copy/rename programs in an external
memory.
File display and Memo function
Data necessary for setups such as operating instructions, drawing data and
text data can be viewed on MAPPS. Text data is editable.
Viewable file types
・PDF ・TXT (editable)
・　Any file that can be displayed
with Internet Explorer is
available
Macro programs such as GOTO, IF and WHILE cannot be used in DNC operating
programs.
●　Improved ease of maintenance
Alarm help function
When an alarm occurs, MAPPS identifies the cause of the trouble and provides
solutions.
Network application systems
Remote Maintenance/Machine Operation Monitoring Service
OP
This system enables access to customer
support services as well as high-speed, largecapacity data transmission between the
machines and Service Center, by using a
network that combines the internal LAN and the
Internet.
●　Download data
●　Remote alarm support
●　Transmission of alarm
information
Application for Data Transmission
[Standard features]
This enables high-speed transfer of programming data between your office
computer and machine, reducing the lead time of pre-machining processes.
