SINUMERIK 840D 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.

Typical applications

High-performance milling and turning is one of the strengths of the SINUMERIK 840D. Further, the SINUMERIK 840D opens up a nearly inexhaustible technology range: From grinding and laser machining to gearwheel machining through to multitasking machining. With its superior system flexibility, the SINUMERIK 840D is the CNC of choice when opening up completely new technology fields.

Overview about the technology

• 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


Modular and scalable

In addition to a scalable NCU performance, the SINUMERIK 840D 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 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 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 is perfectly integrated in the Siemens TIA environment. Totally Integrated Automation stands for unrivalled total integration – from the field level to the production level through to the manufacturing execution level.
