SAN SHING SF-3690 MANUAL LATHES

Technical Description

The SAN SHING SF-3690 manual lathe is a heavy-duty precision machine designed for substantial industrial turning tasks. It features a 36-inch swing capacity and a generous 90-inch distance between centers, allowing for large workpieces to be accommodated efficiently. The spindle bore diameter is 4 inches, providing robust capacity for a variety of tooling and material sizes. Powered by a 15 horsepower motor, the lathe delivers a spindle speed of up to 600 RPM, suitable for heavy-duty cutting and precision machining. The swing over the cross slide is 27.5 inches, enabling the handling of smaller-diameter parts with precision. The lathe bed is constructed from high-strength FC-25 cast iron, engineered for high tensile strength and stability during heavy cutting operations. The lower portion of the bed casting has a box-shaped design with a chip pan for efficient chip management. Its design incorporates multiple spindle speed changes for versatile operation and a rigid structure to ensure precision and durability in demanding production environments. This model is suitable for machining large-scale and heavy components requiring high accuracy and reliability. The SF-3690 combines power, capacity, and precision, making it ideal for industries such as automotive, aerospace, and heavy equipment manufacturing. Its manual operation provides direct control over machining processes, essential for custom or low-volume production requiring expert operator input.
