SAN SHING SF-28330 MANUAL LATHES

Technical Description

The SAN SHING SF-28330 manual lathe is a heavy-duty precision machine designed for versatile metalworking applications. It features a robust swing capacity of 28 inches and a generous distance between centers of 330 inches, enabling it to handle large and long workpieces. The lathe is equipped with a 4-inch spindle bore, allowing for substantial workpiece diameters to pass through the spindle, enhancing its capability for deep cutting operations. Powered by a 15-horsepower motor, the spindle achieves speeds up to 1,000 RPM, providing sufficient torque and speed range for various machining tasks. The swing over the cross-slide measures 19.5 inches, facilitating the machining of moderately sized parts with precision. The lathe bed is constructed of high-strength cast iron (FC-25), designed to ensure structural rigidity and vibration damping for heavy cutting and precision machining. Its design includes a high tensile structure with boxed lower bed portions to maintain stability during operation. The lathe supports 12 spindle speed changes and offers fine longitudinal feeds ranging from 0.05 to 0.7 mm per revolution and cross feeds from 0.025 to 0.35 mm per revolution, allowing controlled and accurate tool movements. Additionally, the spindle nose is compatible with standard attachments (such as A2-8), providing flexibility in tooling. Overall, the SAN SHING SF-28330 is engineered for durability, precision, and heavy-duty performance in manual turning operations.
