SAN SHING SF-2890 MANUAL LATHES

Technical Description

The SAN SHING SF-2890 Manual Lathe is a heavy-duty precision machine designed for large workpieces and robust machining tasks. It features a **28-inch swing over the bed** and a substantial **90-inch distance between centers**, accommodating long and sizable parts. The spindle bore diameter is **4 inches**, allowing the passage of large stock material through the spindle. Driven by a powerful **15-horsepower motor**, it delivers speeds up to **1,000 RPM**, suitable for a wide range of machining operations. The lathe offers a **19.5-inch swing over the cross slide**, providing ample clearance for versatile turning tasks. Constructed with a high-strength cast iron FC-25 bed, the machine ensures superior rigidity and vibration damping for precision cutting under heavy loads. Its bed incorporates a box structure for enhanced stability during intensive use. The spindle assembly supports multiple speeds with 12 change settings for fine speed selection, alongside tapered and Morse taper center types available for tooling compatibility. Feed rates for both longitudinal and cross feeds are finely adjustable, enabling precise control over surface finish and thread cutting. The compound rest movement spans 250 mm, allowing versatile tool positioning. With a quill diameter of 95 mm and 260 mm travel, it supports advanced boring and drilling operations. The SF-2890 is engineered for durability and accuracy in demanding industrial environments, making it suitable for metalworking, heavy fabrication, and custom machining applications requiring robust performance and precision.
