Available from Yama Seiki, the Awea MVP series five-axis machining center features a rigid cross-rail construction with an automatic toolchanger and optional head exchange. The series is available with X- Y-, Z-axis travels ranging from 4,000 × 3,200 × 1,000 mm to 7,000 × 4,000 × 1,400 mm. It can accommodate workpieces ranging from 15,000 to 20,000 kg, depending on the model.
The 4,000-rpm, high-torque, two-step, auto-exchange gear transmission can be equipped with a direct-drive or built-in spindle for cutting flexibility. The spindle, motor, Z-axis ballscrew, twin hydraulic cylinders and gearbox are symmetrically placed to minimize thermal expansion and unbalanced torque for long-term cutting accuracy. The floating unclamping design is said to eliminate force to the spindle bearings during unclamping, ensuring spindle accuracy. The heat-treated table is supported with four heavy-duty guideway rails, two linear guideways and two box ways to support heavy workpieces. The high-performance servo horizontal/vertical automatic toolchanger can change tools in the W axis to decrease non-cutting working time. The machining center also can be equipped with a 35-degree angle head, 90-degree angle head or a universal head. All heads provide 5-degree increments for multi-axis cutting capabilities.
