YCM NH 450A HORIZONTAL MACHINING CENTER

The YCM NH 450A Horizontal Machining Center is a high-rigidity, high-precision machine designed for efficient and versatile horizontal machining. It features a **horizontal spindle with BB40 taper** running up to 15,000 RPM and delivering 25 HP (30-minute rating), enabling high-speed, high-accuracy machining for automotive, aerospace, and general manufacturing applications. The standard table measures 15.75" x 15.75" with an optional 19.7" x 19.7" upgrade, supporting workpieces up to 1,100 lbs with robust structural integrity ensured by a one-piece cast iron base and dual-wall symmetrical column design minimizing thermal deformation. The machine includes a **40-tool automatic tool changer (ATC)** with a rapid 1-second tool change cycle, which can be optionally expanded to 60 tools, enhancing uninterrupted production. It utilizes four-axis control: X (25.2"), Y (24.02"), Z (26.77") travels plus a 360° B-axis for flexible 4-axis machining. The rapid feed rate on linear axes is 787 ipm with 2,362 ipm rapid traverse, ensuring high throughput and reduced cycle times. A **standard rotary table** supports complex part positioning, and a pallet changer with two pallets is optionally available to maximize productivity further. The NH 450A's robust construction includes stepped castings on the X-axis for increased rigidity, precision hand-scraped guideways for long-term accuracy, and a symmetrical dual-wall column to resist deformation. Overall, it balances high rigidity, speed, and precision, suitable for demanding machining environments requiring diverse, high-capacity part production.
