This CNC spindle features a 20.1 horsepower motor delivering high performance at a maximum rotational speed of 12,000 RPM, optimized for medium to heavy-duty machining tasks. It uses a 7/24 taper No. 40, commonly known as CAT40 taper, which has a taper angle of 7 degrees and a nominal taper diameter of 40 mm, providing a balanced combination of rigidity and versatility for various machining operations including milling and drilling. The CAT40 taper allows precise and secure tool holding suitable for a wide range of materials, sustaining accurate engagement under high cutting forces. The spindle's high-speed capability and power make it ideal for applications requiring fast machining with minimal vibration, benefitting from advanced CNC control for fine speed and direction adjustment. This setup enables reliable automatic tool changing and precise control of machining parameters, essential for high throughput and consistent machining accuracy in CNC production environments. The spindle design supports integration with automatic tool changers and advanced electronic high-frequency drives to optimize performance, thermal management, and durability during extended machining cycles.
