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. A high-performance hardware architecture and intelligent control algorithms as well as premium class drive and motor technology class ensure the highest dynamic performance and machining precision. CNC SINUMERIK 840D sl is complemented by a comprehensive range of solutions for integration into IT environments.
At a glance
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.
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.
SINUMERIK panels make operation and visualization easier for machine operators. With their touch screens, they open the way to create new and unique machine operating philosophies. In conjunction with the state-of-the-art SINUMERIK Operate, touch and gesture operation are establishing themselves in the production domain.
SINUMERIK blackline plus operator panels utilize the 16:9 format, have an attractive modern design and provide the basis for completely new operating concepts. They are available in sizes ranging from 15 to 24 inches. In the basic MCP 398C version, the add-on machine control panels are identical for all screen formats – and can be expanded using additional modules.
State-of-the-art and user-friendly
Modular and standard across the board
The SINUMERIK OP 015 black is an ultramodern operator panel for SINUMERIK 840D sl systems. It offers the highest degree of operator friendliness with its 15" multitouch wide screen.
Siemens is the pioneer when it comes to protecting man and machinery. For almost two decades now, SINUMERIK Safety Integrated has been the benchmark for safety technology integrated in the system for machine tools. SINUMERIK Safety Integrated involves intelligent system functions that provide the highest level of operator friendliness and safety for both operator and machine. For example, setting up the machine with the protective door open.
Teamed-up with the SINAMICS drive system, SINUMERIK 840 controls offer the optimum platform for implementing safe machine concepts.
From software release 4.8 SP 2, Safety Integrated plus is also available for SINUMERIK 840D sl. A real highlight is the graphically supported commissioning with screen forms that significantly simplify parameterizing the safety functions.
The SinuTrain offline programming station brings SINUMERIK Operate to the PC, including an animated machine control panel, to create a training situation that is very similar to that experienced in reality. This facilitates an easy transition from a training into a practical environment. This powerful tool allows NC programs to be programmed offline at a PC in an environment that is close to reality; these NC programs can then be directly transferred to the CNC. CNCs can be programmed in a training environment exactly as they will be subsequently used in real machines controlled by SINUMERIK. Perfectly tailored training packages are available as well as a free-of-charge basic version – everything you need for efficient training in your own environment.
Supplementary system components
SINUMERIK 840 controls, teamed up with SINAMICS drives and SIMOTICS motors are optimally designed to address the requirements of standard machines.
SINAMICS S120 is synonymous with performance and flexibility when it comes to equipping machine tools. In addition to a wide range of motor modules up to a power rating of 300 kW, there is also an infeed unit with a controlled DC link. This ensures the shortest spindle acceleration times, and facilitates perfect reactive power compensation for the complete machine.
SINAMICS S120 Combi combines the performance of the modular SINAMICS S120 in a compact, rugged design. One infeed and up to four Cabinet Modules are integrated in one housing. This drive is the ideal basis for equipping compact standard machine concepts with a spindle power of 15 kW and up to five feed axes.
High stall torques, high maximum speeds and smooth running characteristics make SIMOTICS servomotors the optimum feed drive for machine tools. The high degree of protection, strong bearings and rugged design mean that these synchronous servomotors have outstanding reliability.
Going beyond conventional rotary motor principles, the SIMOTICS range also encompasses linear and torque motors with a high dynamic performance. Elasticity, backlash and friction in the machine drive train – along with mechanical transmission elements – can be almost completely eliminated when using SIMOTICS L-1FN3 linear motors. Further, using SIMOTICS T-1FW6 torque motors, completely new technological domains can be addressed, for example, turning on milling machines.
An outstanding portfolio is obtained by teaming-up the high level of competence in spindle design and construction of Weiss Spindeltechnologie GmbH with Siemens' long tradition of building electric motors. This unique portfolio supports all types of spindle solutions – from classic mechanical spindles based on SIMOTICS M-1PH8 mounted spindle motors, through SIMOTICS M-1FE1 and M-1FE2 – up to hybrid and high-performance motor spindles.
