KERN PYRAMID NANO VERTICAL MACHINING CENTER

Technical Description

The KERN Pyramid Nano is a 5-axis vertical machining center engineered for ultra-precision and superior surface quality with a compact work envelope of 19.68 x 19.68 x 15.75 inches (X, Y, Z). It utilizes hydrostatically supported and driven linear axes, offering virtually wear-free operation that ensures lifelong positioning accuracy with a position deviation as low as ±0.3 µm. The machine attains high accelerations up to 10 m/s² and feed rates up to 30 m/min, enabling efficient machining of complex geometries. Its 42,000 RPM spindle equipped with HSK40 taper delivers 14.9 kW power for high-speed, high-performance cutting, suitable for hardened steels up to 64 HRC. An integrated automatic tool changer with 75 positions and a fully automated workpiece changer facilitate unmanned, multi-shift operations with minimal downtime. The CNC control is provided by the Heidenhain iTNC 530 or TNC 640, featuring advanced digital drive technology for simultaneous 5-axis interpolation, dynamic precision controls, tool monitoring, and programmable cycles that optimize machining accuracy and safety. Thermal management with multiple cooling circuits stabilizes spindle, hydraulic systems, and machine structure, while the rigid gantry construction with a mineral-casting machine base ensures excellent vibration damping. Compact dimensions enable efficient factory floor usage. Optional jig grinding functionality allows combined milling and grinding in one setup. Overall, the KERN Pyramid Nano excels in applications demanding nanometer-level precision, maximum surface finish, and high productivity in unmanned serial production environments.
