Product Highlight PRODEX 2019


SINUMERIK 840D sl is considered to be the standard in the premium class CNCs, which is certainly justified. Maximum CNC performance, along with a high degree of flexibility and openness – which has been unachievable up until now – represent the basis for almost every machine concept.

At a glance

SINUMERIK Operate Display Manager - efficient user interface design

Individual operating concepts for more versatility and convenient machine handling

The SINUMERIK Operate Display Manager helps you to get the most out of your large screens. Dividing the screen space into multiple areas allows you to take in a lot of information at a single glance. Intuitive gesture and multi-touch operation and the clearly structured display of various applications, widgets, or a virtual keyboard facilitate fast, user-friendly operation. The appearance of the Display Manager screen surface can be adjusted at any time to suit the individual preferences of the operator.

SINUMERIK 840 - the open CNC for modular machine concepts

SINUMERIK 840D sl offers an almost inexhaustible performance potential: Thanks to its drive-based, high-performance NCUs (Numerical Control Units) with state-of-the-art multicore processor technology, up to 93 axes in 30 machine channels can be controlled in the NCU link. 

In addition to the scalable NCU performance, SINUMERIK 840D sl also has a high degree of modularity when it comes to the operating components. A flexible M:N operating concept – for example, any operator panel can be combined with the NCU – makes the SINUMERIK 840D sl the ideal solution when operating high-end machine tools.

Communication at every level

SINUMERIK 840D sl is perfectly embedded in the Siemens TIA environment using PROFINET. Totally Integrated Automation stands for a unique level of seamless integration – from the field, through production, up to the company supervisory level.


Benchmark in open architecture

The openness of the SINUMERIK 840D sl is second to none. The CNC can be optimally adapted to the machine's technology. For instance, the operating system can be supplemented and adapted, or even robots and handling systems can be integrated.


Utilize the bandwidth of machining technologies

Milling and turning at the limit is one of the strengths of SINUMERIK 840D sl. Further, SINUMERIK 840D sl allows an almost inexhaustible range of technologies to be addressed: from grinding and laser machining, through gearwheel- up to multitasking machining. With its outstanding system flexibility, SINUMERIK 840D sl is also the first choice when it comes to addressing completely new fields of technology.
