In 1996 Siemens released the SINUMERIK 840D as the next generation and flagship of its CNC portfolio. 840D included features such as universal technologies, simple high-level programming, expanded G-Codes, SIMODRIVE 611D digital drives and integrated the Step 7 PLC CPUs with associated peripherals. Safety Integrated was another major technology leading breakthrough when introduced with 840D. The CNC was given a new lease on life as the 840D Powerline in the early 2000s.
The successor SINUMERIK 840Dsl was released in the mid-2000s, however 840D Powerline’s success ensured it remained actively used by OEMs well into the 2010s. With the recent release of SINUMERIK ONE, SINUMERIK 840D and associated SIMODRIVE 611D will reach the end of its lifecycle in early 2024. This means limited and diminishing availability of Siemens tested and guaranteed spare parts. Anyone with 840D or 840D Powerline controls on their valued machine tools should consider a retrofit to extend the life cycle of these machines. When it comes to the longevity and performance of your equipment, trust is crucial. We strongly advise against relying on grey market, non-genuine spare parts, as they may jeopardize the reliability and safety of your CNC machines. By choosing a retrofit solution you benefit from enhanced functionality and improved performance and the peace of mind of readily available genuine spare parts.
We recommend you pay attention to the new SINUMERIK ONE, Siemens' latest CNC control system, offering advanced features and unparalleled performance. It supports digital twin technology for virtual commissioning and optimization, integrates open communication standards for connectivity, employs adaptive control algorithms for real-time tool path optimization to enhance productivity. And remains the class leader for 5-axis machining, multi-tasking, CNC robotics and complex applications.
With the user-friendly SINUMERIK Operate interface, advanced motion control, and comprehensive safety functions based on the integrated Safety PLC CPU (S7-1500F), SINUMERIK ONE empowers manufacturers to enhance productivity, quality, and flexibility in their machining processes.
