阅读:138次

Modular structure

Machine tool operation panel, CNC control unit, drive system and motor have many choices in hardware, which can be matched as needed to suit different applications

Networked connection can realize data communication at all levels

Machine tool enters factory digital network: Industrial Ethernet

System internal interconnection: Industrial Ethernet

Drive SINAMICS S120 components interconnection: drive Cliq drive bus

Machine tool IO control: PROFIBUS industrial fieldbus; PROFINET industrial fieldbus

Various intelligent devices: devices supporting PROFIBUS / PROFINET industrial fieldbus

Multiple NCU connections: NCU link

Excellent performance

The NC unit controls up to 93 feed axes / spindles, and any number of PLC axes can control up to 30 processing channels

The new SINUMERIK black line plus series panels are available in 15 ", 19", 22 ", 24" sizes (classic panels are available as usual)

The new ipc427e offers 240g solid state drives

SINAMICS S120 driver with high dynamic performance can cover 300kW in machine tool application

Common rotary servo motors 1FK7 / 1ft7 and 1ph8 meet most applications

Direct drive motors - linear motors, torque motors and motorized spindles are required for high-performance machine tools

Powerful function

Five axis RTCP, three-dimensional tool compensation, anti-collision function, spatial error compensation function, complex spatial transformation, multiple axis coupling modes, and many functions cannot be listed one by one

Siemens has accumulated a variety of process knowledge, which can be used for a long time

Turning, milling, grinding, stamping, laser processing, composite processing, handling equipment and robot control

The application of composite technology makes the machine tool a generalist and greatly improves the machining efficiency and accuracy

Typical applications: milling and milling compound, turning and milling compound, compound of increasing and reducing materials

Provide industry solutions

Siemens can provide solutions for many industries such as die processing, aerospace and so on

Intuitive and unified operation mode


The SINUMERIK operate operation interface complies with the manual operation rules and can be started after simple training. Installing sinutrain software on the computer is like operating a real CNC system. A large number of short video tutorials, you can learn operation programming anytime and anywhere

Open architecture

Through a variety of development tools of create myhmi, the general system can be turned into a special system, or even a system

Security integration

Machine tools are becoming more and more complex, and the operation is more high-speed and efficient, but we should also pay attention to the safety of machine tools and personnel. Siemens CNC has a powerful f-plc and drive system to provide safety integrated solutions, which meet the standards and protect the safety of machine tools and personnel

Support digital applications


Whether it is stand-alone application, factory network or direct to the cloud, the machine tool data and production data are clearly displayed
