The KAAST Machine Tools C-TURN 315/1500 is a precision manual engine lathe designed for heavy-duty metalworking tasks. It features a **24-inch swing over the bed** and a **58.5-inch distance between centers**, enabling machining of sizable workpieces. The spindle bore diameter is **3.30 inches**, accommodating larger tooling and bar stock. Powered by a robust **10 horsepower motor**, the lathe reaches spindle speeds up to **1,293 RPM** with multiple stepped gear settings for versatile speed control. The machine bed width measures **350 mm (13.5 inches)**, providing a stable and rigid foundation that supports accurate, vibration-free machining. It includes hardened and precision-ground guideways for durability and precision, capable of threading in metric, Whitworth, module, and diametral standards without gear changes. The tool holder travels 150 mm along the Z-axis and 330 mm on the X-axis. Noteworthy features include an optional digital 3-axis readout, a 4-post toolholder system, and coolant delivery, enhancing operational efficiency and ease of use. The lathe also supports various chuck mounts (standard D1-8), with optional larger spindle bores and motors available for specialized requirements. Its design emphasizes low noise operation and ease of maintenance, suitable for toolrooms and general machining shops requiring accuracy and reliability in a manual lathe platform.
