KUMMER K 250 CNC LATHES

Technical Description

The Siemens SINUMERIK 840D is a high-performance CNC controller engineered for advanced multi-axis machining operations. This modular, scalable system supports up to 31 axes and spindles with up to 10 machining channels, delivering exceptional flexibility for complex production requirements. The controller features integrated high-speed motion control with a position control cycle time capability of less than 0.005 seconds, ensuring precision in milling, turning, grinding, laser cutting, and multi-axis applications. The SINUMERIK 840D incorporates an integrated SIMATIC S7-300/S7-1500 PLC, enabling seamless automation integration and enhanced connectivity. Its Industry 4.0-ready architecture supports multiple communication protocols including PROFINET, EtherCAT, and OPC UA, facilitating digital twin technology for virtual commissioning and optimized machining performance. The system accommodates drive-based modular CNC configurations with comprehensive motor compatibility, including AC induction, brushless, servo, and stepper motor drives. The controller offers versatile HMI display options available in 10.4", 15.6", and 19" touchscreen formats for operator interface flexibility. It supports synchronized actions, correlated position access (COPA) cycles, and programmable spindle speed limitations, with high-speed digital input/output capabilities for advanced probe and measurement functions. The SINUMERIK 840D sl (Solution Line) variant provides an extended capability platform with up to 93 axes capability. Programming adheres to DIN 66025 standards and supports constant cutting rate and grinding wheel peripheral speed functions, making it ideal for aerospace, automotive, and precision engineering applications requiring reliable, repeatable multi-axis control.
