SINUMERIK – CNC portfolio for the global world of machine tools

SINUMERIK CNC controllers provide the right solution for every machine concept – from basic CNC standard machines to standardized machine concepts through to modular premium machine concepts.

SINUMERIK 808D: The entry-level CNC for basic standard machines

The SINUMERIK 808D is a panel-based CNC controller for low-end applications. This compact and user-friendly entry-level solution is used for basic turning and milling applications.

SINUMERIK 828D and SINUMERIK 828D BASIC: The compact CNC for standardized machine concepts

SINUMERIK 828 controllers are optimally suited for standardized machine concepts which are manufactured with reduced modularity, in large quantities.

SINUMERIK 840D sl: The open CNC for modular machine concepts

The SINUMERIK 840D sl provides maximum openness and flexibility. This makes SINUMERIK 840D sl the ideal CNC for machines whose mechanical configuration shall be individually tailored to the needs stated by the user.


Outstanding performance, simply smart

Compact and robust

Thanks to its panel-based CNC design requiring only few interfaces and an operator panel with degree of protection IP65, the SINUMERIK 808D / 808D ADVANCED is perfectly prepared for the use in harsh environments. With its small dimensions, it can be used on compact machines. At the same time, the SINUMERIK 808D / 808D ADVANCED allows convenient operation with short-stroke keys and the well-known SINUMERIK softkeys.

Optimized for basic turning and milling applications

With its technology-specific features, the SINUMERIK 808D / 808D ADVANCED is perfectly preconfigured for turning and milling applications. The scope of applications ranges from basic standardized milling machines and basic machining centers to cycle-controlled turning machines through to basic full-CNC lathes.

Ideal for beginners

With the innovative, integrated startGUIDE, the SINUMERIK 808D / 808D ADVANCED is the ideal partner for entry-level CNC users. In addition to CNC operation and programming, commissioning is also explained graphically and interactively. The uniform SINUMERIK operating and programming philosophy makes the SINUMERIK 808D / 808D ADVANCED the ideal entry-level controller for the world of SINUMERIK applications.


The most powerful controller in the compact class

Robust and maintenance-free

An operator panel front made of magnesium die cast, a panel-based CNC design requiring less interfaces together with a high degree of protection make SINUMERIK 828 controllers a reliable partner also in harsh environments. By using a fanless configuration without hard disk and the NV-RAM storage technology without buffer battery, SINUMERIK 828D and SINUMERIK 828D BASIC are completely maintenance-free CNC controllers.

Standardized turning and milling

With its technology-specific system software, SINUMERIK 828D and SINUMERIK 828D BASIC are ideally suited for standardized turning and milling machines. The scope of application ranges from vertical and basic horizontal machining centers – including moldmaking applications – through to turning centers with counterspindle, driven tools and Y-axis.


A fully-fledged QWERTY CNC keyboard with short-stroke keys together with a high-resolution 8.4“/10.4“ TFT color display allow to conveniently operate SINUMERIK 828D and SINUMERIK 828D BASIC. USB, CF card and RJ45 interfaces on the operator panel front allow to quickly and conveniently transfer CNC data.

Scalable CNC performance

In addition to two SINUMERIK 828D CNC performance versions, the SINUMERIK 828D BASIC provides a favorably-priced entry into the compact class. Thus, the most powerful compact class controller perfectly fits to the performance required for standardized machine concepts.


Ultimative performance in the premium class

SINUMERIK 840D sl – Description

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 – Typical applications

High-performance milling and turning is one of the strengths of the SINUMERIK 840D sl. Further, the SINUMERIK 840D sl 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 sl is the CNC of choice when opening up completely new technology fields.
