SUMMIT 30-4/240 MANUAL LATHES

Technical Description

The SUMMIT 30-4/240 Manual Lathe is a heavy-duty engine lathe designed for precision metalworking with a bed size of 32" swing over bedways and 20 feet between centers. It features a 33" maximum swing, including 23.5" over the cross slide and a 40" swing in the removable gap for machining larger workpieces. The lathe is equipped with a robust 4.125" diameter spindle through-hole, enabling long stock to pass through the spindle for versatile operations. Spindle speeds range from 21 to 1010 RPM, accommodating a wide array of cutting conditions. This lathe includes both inch and metric threading capabilities alongside a thread dial for accurate thread cutting, supported by a taper turning attachment for precise taper machining. The toolpost is a quick change design, enhancing tooling flexibility and reducing setup time. The standard 24" diameter 4-jaw chuck securely holds irregular or round parts, while steadyrest support ensures stability during extended workpiece turning. Hardened bedways provide durability and maintain precision over prolonged usage. Electrically powered by a 30 HP motor with 220/440 Volt supply, the lathe is built for industrial-grade applications, supported by chip pans to manage debris effectively. These features combine to deliver a reliable, large-capacity lathe suitable for heavy manufacturing and maintenance environments, providing long-term performance and precision control.
