YITONG VMC-650L3 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a robust work envelope with X, Y, and Z travel dimensions of 26 inches, 17.7 inches, and 19.7 inches respectively, providing ample space for medium to large workpieces. The machine table measures 17.7 inches in width and extends to 31.5 inches in length, ensuring stable support and flexibility for various fixturing setups. Equipped with a BT40 taper spindle, the machine delivers high rigidity and precision, making it suitable for demanding milling, drilling, and tapping operations. The BT40 taper adheres to JIS B 6339-2 (MAS 403) standards, featuring a taper angle of 8° 17' 50'' and a tolerance quality of AT3, ensuring accurate tool engagement and reliable repeatability. The spindle is designed for both metric and imperial tooling, with a symmetrical structure that enhances balance and stability at high speeds. The tool holder is case-hardened to 60–2 HRC with a core tensile strength of at least 950 N/mm², guaranteeing durability under heavy cutting loads. The BT40 taper supports interior coolant supply through the center (form JD) and optionally through the collar (form JF), improving chip evacuation and tool life. The machine’s design facilitates efficient automatic tool changes and maintains tight concentricity, critical for precision machining. With its combination of generous travel, sturdy table, and high-performance BT40 spindle, this machining center is ideal for a wide range of industrial applications requiring accuracy, reliability, and versatility.
