The DAWN FOUNDRY DF-400/1500 is a heavy-duty manual engine lathe designed for precision turning operations and general machining applications. With a swing capacity of 36.02 inches, this machine accommodates medium to large-diameter workpieces, while the swing over cross slide of 24.02 inches enables efficient tool positioning and feed control. The extended centers measurement of 142.52 inches provides substantial between-centers capacity, making it suitable for machining longer cylindrical components and shafts requiring extended work lengths. The lathe features a 4.13-inch spindle bore, facilitating the installation of various chuck sizes and work-holding devices for diverse workpiece geometries. This specification supports efficient material removal rates and accommodates standard tooling configurations common in traditional machine shops. The manual operation characteristic indicates direct operator control over spindle speed, feed rates, and tool advancement, providing experienced machinists with tactile feedback and precision control essential for custom work and prototype development. Built with the durability and reliability typical of foundry equipment, the DF-400/1500 integrates robust cast-iron construction to minimize vibration and maintain dimensional accuracy during extended machining cycles. The machine's configuration makes it well-suited for job shops, educational institutions, and manufacturing facilities requiring versatile turning capabilities for both ferrous and non-ferrous materials. Its manual control system ensures straightforward operation and maintenance while delivering consistent results for conventional lathe operations including threading, boring, facing, and taper turning applications.
