The SINUMERIK 840D sl provides maximum openness and flexibility. It is the ideal CNC for machine tools whose mechanical configuration shall be individually tailored to the needs
stated by the end-customer.



SINUMERIK 840D sl is with good reason considered as the measure in the CNC premium class. Utmost CNC performance as well as unreached flexibility and openness are the basis for nearly every machine concept.

SINUMERIK 840D sl Machine

Technical specs

  • Drive-based modular CNC

  • Multi-technology CNC

  • Up to 93 axes / spindles

  • Up to 30 machining channels

  • Modular panel concept

  • Up to 19“ color display

  • SIMATIC S7-300 PLC


  • Modular and scalable
    In addition to a scalable NCU performance, the SINUMERIK 840D sl also provides excellent modularity of the operator components. With a flexible M:N operator concept – e.g. the combination of arbitrary operating fields with the NCU – the SINUMERIK 840D sl can be ideally adjusted to the operator philosophy applied by state-of-the-art premium machine concepts.

  • Benchmark in open architecture
    The open system architecture of the SINUMERIK 840D sl is unique. For example, the CNC can be optimally adjusted to the machine technology and shows a high degree of freedom in production automation.

  • Communicative at all levels
    With PROFINET, the SINUMERIK 840D sl is perfectly integrated in the Siemens TIA environment. Totally Integrated Automation stands for unrivaled total integration – from the field level to the production level through to the manufacturing execution level.
