💡 What is Siemens SINUMERIK

The Siemens SINUMERIK family is one of the most advanced computer numerical control (CNC) systems in the world.
It is the brain that governs machine tools and production systems, translating digital commands into precise, perfectly synchronized movements.

Thanks to its modular architecture and seamless integration with SIMODRIVE and SINAMICS drive systems, SINUMERIK controllers deliver high performance, reliability, and scalability — from single-axis machines to the most complex multi-axis production lines.

⚙️ Main technical features

High-performance multi-axis control with simultaneous interpolation
Micrometric precision in positioning movements
Full compatibility with SIMODRIVE, SINAMICS and Siemens motors
Integrated interfaces: PROFINET, PROFIBUS, Ethernet/IP, DRIVE-CLiQ
Upgradable and customizable Siemens CNC software
Advanced functions: 3D simulation, tool management, intelligent diagnostics
Available versions: SINUMERIK 802D, 810D, 840D, 840Di, 828D, 840D sl

Each version is designed to meet specific automation needs—from compact machine tools to high-speed production lines with automated tool management.

🏭 Typical applications

SINUMERIK systems are used across all major areas of industrial mechanics:

• CNC machining centers for milling, turning and grinding

• Laser, plasma and waterjet cutting machines

• Robotic lines and handling systems

• Machine tools for automotive, aerospace, energy and molding

Their high reliability and long service life make SINUMERIK the ideal choice for companies seeking precision, productivity and fully digitalized processes.
