Technical Description
The Siemens Sinumerik 840D CNC Control is a high-performance, modular CNC system designed for advanced machining applications, offering maximum flexibility, scalability, and precision. This control system supports up to 31 axes and 10 machining channels, making it ideal for complex multi-axis operations such as milling, turning, grinding, and laser cutting. Integrated with a SIMATIC S7-300/1500 PLC, the Sinumerik 840D ensures seamless automation, enhanced connectivity, and Industry 4.0 compatibility via PROFINET, EtherCAT, and OPC UA. The system features a user-friendly HMI with touchscreen display options (10.4", 15.6", or 19"), providing intuitive access to machine status, parameters, diagnostics, and setup functions. The control is optimized for high-speed motion control and digital twin technology, enabling virtual commissioning and improved machining performance. For the specified machine, the X-axis travel is 11.00 inches, Z-axis travel is 41.50 inches, and the distance between centers is 59 inches, with a maximum swing over the bed of 27.60 inches and a max cutting/turning diameter of 20.50 inches. The bar capacity is 3.80 inches, spindle bore is 4.20 inches, and the spindle speed reaches 3,200 RPM, powered by a 72 HP spindle motor with an A2-8 spindle nose. The machine is equipped with 12 tool positions, live milling capability up to 3,000 RPM, C-axis resolution of 0.001°, and a Y-axis travel of 7.9 inches (±3.9 inches). This configuration delivers exceptional accuracy, productivity, and versatility for demanding industrial applications.
