HESSAPP DVT 400 CNC LATHE

Technical Description

The SINUMERIK 840C is a premium-class CNC control system that delivers advanced machining capabilities for turning operations. This 2-axis turning center features a 10-inch chuck with a maximum turning diameter of 19.68 inches and a swing capacity of 20.07 inches, making it suitable for medium-sized cylindrical workpiece production. The control system supports multi-axis coordination with programming capabilities for linear, rotary, contouring, and simultaneous axes operations. The SINUMERIK 840C provides comprehensive G-code functionality including tool radius compensation, constant cutting speed control, spindle threading operations, and rigid tapping with position-controlled spindle modes. It integrates SIMODRIVE 611-D servo drive technology for precise axis control and features MMC (Man-Machine Communication) interface with diagnostics across multiple operational areas including NCK, servo, and drive functions. The system supports computer link connectivity via bus connections for data exchange with higher-level host systems, enabling efficient program transfer and operational synchronization. Advanced features include velocity modification, block change behavior control, tool offset management, and cycle programming capabilities. Built-in alarm diagnostics provide comprehensive monitoring across PLC, axis-specific, and spindle-specific functions for reliable operation. Weighing approximately 10 tons, this turning center combines the robust construction necessary for industrial production with the flexible, open architecture characteristic of Siemens CNC controls, delivering maximum performance for precision turning applications.
