SMEC CO., LTD SL 3500Y HORIZONTAL MACHINING CENTER

Technical Description

The SMEC SL 3500Y is a heavy-duty, ultra-precision horizontal machining center designed for high-performance turning operations. It features a single main spindle with a 12-inch (304.8 mm) chuck diameter and a maximum swing of 33 inches (838.2 mm), enabling machining of large-diameter components. The spindle operates at up to 2,800 RPM and is powered by a 25 HP motor, with an optional upgrade to 35 HP for enhanced performance. The machine supports three controlled axes (X, Y, and Z), accommodating simultaneous cutting with one tool. Its rigid structure includes a 30-degree torque tube type bed to withstand heavy cutting forces and reduce vibration, improving machining accuracy and surface finish. The SL 3500Y incorporates SMEC's advanced technology such as an independent transmission system to minimize vibration and a head assembly with radiator fans to maintain thermal stability during extended operation. The CNC control is typically Fanuc-based, providing reliable and precise programming for complex tasks. Its capabilities support substantial machining lengths up to approximately 780 mm (30.7 inches) or longer with certain configurations, and the tool turret utilizes a robust Curvic coupling for quick, precise tool changes. Overall, the SL 3500Y combines power, rigidity, and precision to meet demanding turning and milling requirements for large, complex parts in industrial manufacturing settings.
