Modular and scalable

SINUMERIK 840D sl BASIC with SINAMICS S120 Combi – Entry into the premium class with up to 6 axes.

Optimum compact machine concepts can be developed by combining the SINUMERIK 840D sl BASIC with the SINAMICS S120 Combi compact converter.

SINUMERIK 840D sl with SINAMICS S120 – CNC performance with up to 93 axes.

As well as scalable NCU performance, the SINUMERIK 840D sl also offers a high degree of modularity of the operator controls. With a flexible M:N operating concept – such as the free combination of operator panels with the NCU – the SINUMERIK 840D sl can be ideally adapted to the operating philosophy of modern premium machine concepts.

Modular operating concept

Engineering

There is nothing to rival the openness of the SINUMERIK 840D sl system. With SINUMERIK Integrate, the CNC control can be optimally adapted to the technology of the machine. SINUMERIK Integrate also provides a high degree of freedom in production automation. For example, the operating equipment can be added to and adapted, and even robots and handling systems can be integrated. The openness in the CNC kernel and the drive enables unique mechanical concepts – such as adapted control algorithms and specific kinematic transformations – to be implemented.

Communication at all levels

SINUMERIK 840D sl fits seamlessly into the Siemens Totally Integrated Automation world with PROFINET, the leading Industrial Ethernet standard. Totally Integrated Automation stands for unique consistency – from field level through production to the corporate level.

The result: Optimum interaction between all components of the automation system and, as a consequence, an extremely transparent, highly available manufacturing process.

Perfect drive solutions for machine tool equipment

SINAMICS S120 Combi offers the performance capabilities of the modular SINAMICS S120 system in a compact, rugged design. An infeed and up to 4 Motor Modules are integrated into a single enclosure. The intelligent expansion by 2 Motor Modules has made the SINAMICS S120 Combi the perfect basis for equipping compact, standardized machine concepts with a spindle power of up to 15 kW and up to 5 feed axes.

SINAMICS S120 is synonymous with performance capability and flexibility in the equipment of machine tools. Not only a wide range of Motor Modules with up to 300 kW power but also an infeed with a closed-loop DC link are available. This provides the shortest spindle acceleration times, and enables perfect reactive current compensation of the entire machine (cos ? = 1). Furthermore, Dynamic Servo Control (DSC) offers a unique closed-loop position control process for the highest dynamic response of feed and spindle motors.

All components of SINAMICS S120 and S120 Combi, including the SIMOTICS motors and encoders, are connected to the SINUMERIK 840D sl via the high-­speed DRIVE?CLiQ interface. In this way, the CNC control detects the electronic rating plates – that is the relevant performance data and production data – of all the connected components. This ensures not only automated commissioning, but also optimal diagnostics, faster service and efficient maintenance.

SIMOTICS motors for the highest accuracy and dynamic performance in the machine tool.

SIMOTICS 1FK7/1FT7 servomotorsare characterized by a high stall torque, high maximum speed and perfect true running properties. High degree of protection, strong bearing unit and a vibration-free mounting ensure absolutely reliable synchronous servomotors. High quality magnetic materials achieve a very high power/weight ratio and so the smallest motor dimensions. This makes installation possible in even the most cramped conditions.

SIMOTICS 1FN3 linear motorscan almost completely eliminate elasticity, backlash and friction characteristics, as well as natural vibration of the machine drive train.

SIMOTICS 1FW6 torque motors open up completely new fields of technology, such as turning in milling machines (multi-tasking).

SIMOTICS motor spindles achieve outstanding levels of productivity and precision in a single machine tool. They are designed to ensure optimum performance and excellent workpiece quality. The mechanically integrated motor solutions are extremely compact, and achieve maximal rigidity, which is the precondition for the highest speeds and precise true running.

The portfolio, which optimally supports every type of spindle solution, ranges from conventional 1PH8 mounted spindle motors and synchronous 1PH2/1FE1/1FE2 built-in spindle motors to mechanical spindles, and 2SP1 hybrid and motor spindles.
