YCM NH800B HORIZONTAL MACHINING CENTER

Technical Description

The YCM NH800B Horizontal Machining Center is a high-precision, rigid CNC machine designed for demanding machining applications. It offers substantial travel capacities of 51.181 inches (X-axis), 43.307 inches (Y-axis), and 43.307 inches (Z-axis), accommodating large workpieces efficiently. The machine features a robust one-piece T-base foundation with rib construction and a dual-wall column design to maximize structural rigidity and minimize thermal deformation during prolonged operations. Its spindle headstock is cast in one piece to ensure cutting accuracy, while oversize roller guideways and high dynamic servo-driven pre-tensioned ball screws contribute to precise control and rigidity. Powered by a 60.3-horsepower built-in motorized spindle capable of reaching 10,000 RPM, the NH800B delivers a high torque output with minimal vibration owing to its micro oil-air lubrication for ceramic angular ball bearings and circulated oil jacket cooling. The machine supports a 40-tool automatic tool changer with a BBT50 tool taper, enabling quick tool changes and high machining efficiency. The CNC system controls three axes with a rapid feed rate of up to 50 m/min. The machining center includes a large 31.496 x 31.496-inch pallet, which supports up to 2,000 kg loading capacity with fast servo motor-driven automatic pallet changes taking approximately 20 seconds. Its design incorporates dual-drive technology for enhanced stability and machining accuracy, making it suitable for multiface machining and high-production environments requiring superior precision and reliability.
