STAR ST-38 HORIZONTAL MACHINING CENTER

Technical Description

The STAR ST-38 Horizontal Machining Center is a Swiss-type automatic lathe engineered for complex mill-turn machining with a maximum turning diameter and bar capacity of 1.5 inches (38 mm) and a maximum turning length of approximately 13.78 inches (350 mm). It features a powerful main spindle rated at 15 HP with a speed of up to 7,000 RPM, complemented by a sub-spindle of 10 HP also reaching 7,000 RPM, enhancing multi-task machining capabilities. The machine is equipped with two primary front turrets, each capable of holding up to 10 turning and 10 rotary tools, allowing up to three tools to cut simultaneously, which significantly improves productivity and cycle times. Its secondary mill/drill functions are standard on-center, off-center, and with both 'C' and 'Y' axis control, providing versatile milling and drilling flexibility. The ST-38 supports deep hole drilling and precise rotational control through C-axis indexing, essential for threading and complex geometrical features. The machine's advanced Star Motion Control system optimizes tool paths and reduces idle time, enabling highly efficient single-set-up production of complex parts. Additional features include high-frequency turning, rapid feed rates up to 30 m/min on the main axes, and a coolant tank capacity of 245 liters. With a robust construction weighing approximately 6,250 kg, it is suited for high-precision applications in medical, automotive, and aerospace industries, handling parts up to 150 mm in length with front-ejection capability and tool presetting for rapid changeovers.
