KIRA KN40VA VERTICAL MACHINING CENTER

Technical Description

This CNC machine features a robust 7.5 kW spindle motor delivering up to 8,000 RPM, optimized for versatile machining operations. It is equipped with a 12-position Automatic Tool Changer (ATC) supporting CAT 40 taper tooling, a widely adopted standard known for balancing rigidity and versatility. The CAT 40 taper has a nominal taper diameter of 1.75 inches (44.45 mm) with a taper angle of 7/24 (approximately 7 degrees), designed for secure, high-precision tool holding suitable for a range of materials and machining tasks. The machine is controlled by a Fanuc 21i-M CNC system, enabling complex part programming and high-accuracy tool management. Its physical footprint measures 130 inches by 138 inches, with a substantial weight of 6,600 pounds, indicating a rigid and stable construction suited for heavy-duty machining environments. The combination of high spindle power, moderate speed, and a 12-tool ATC allows for efficient production cycles with minimal downtime due to tool changes. The CAT 40 taper interface supports quick and precise tool changes and distributes machining loads effectively, enhancing tool life and machining accuracy. This configuration makes the machine well-suited for precision milling, drilling, and finishing operations in metalworking and similar industrial applications.
