KERN MICRO VARIO VERTICAL MACHINING CENTER

Technical Description

The KERN Micro Vario vertical machining center features a compact working envelope with travel dimensions of 13.78 inches (X), 8.66 inches (Y), and 9.84 inches (Z), supporting high-precision 5-axis simultaneous machining. Its spindle delivers up to 42,000 RPM powered by a 15 kW motor, utilizing an HSK40 taper for fast, reliable tool changes via a 210-position automatic tool changer (ATC). The machine is controlled by a Heidenhain TNC 640 CNC system, renowned for its advanced digital control architecture that supports interpolation of up to five axes simultaneously and spindle speeds digitally controlled up to 100,000 RPM. The TNC 640 offers rapid block processing times under 0.5 ms, enabling efficient execution of complex 3D contours with superior surface finish and contour fidelity via functions like Tool Center Point Management (TCPM), 3D tool compensation, and Dynamic Precision enhancements (CTC, PAC, LAC, MAC). It incorporates optimized motion control with adaptive feed and load compensation, active vibration damping, and dynamic collision monitoring for safe and precise operation. The control supports comprehensive automated machining capabilities, including tool and workpiece measurement with touch probes, pallet and tool management, and seamless integration with CAM workflows. This machine combines high-speed, accurate 5-axis machining with advanced CNC functionality, making it ideal for complex, high-precision micro machining tasks requiring excellent surface quality and throughput.
