SUMMIT 30-6 X 80 MANUAL LATHES

Technical Description

The Summit 30-6 x 80 is a heavy-duty manual engine lathe designed for industrial toolroom and production machining applications. This machine features a 30-inch swing capacity over the bed with an 80-inch distance between centers, enabling the machining of large cylindrical workpieces up to 30 inches in diameter and 80 inches in length. The lathe is equipped with a substantial 6.09-inch spindle bore, allowing for efficient through-spindle work and accommodating larger diameter workpieces for increased machining flexibility. Powered by a robust 20-horsepower motor operating at a maximum spindle speed of 700 RPM, this lathe delivers the torque and cutting force necessary for heavy stock removal and precision finishing operations. The 22-inch swing over the cross slide provides ample clearance for tool access and workpiece manipulation. With overall dimensions of 54 inches deep by 64 inches high by 164 inches long, the machine occupies significant floor space but offers substantial work envelope. Weighing 8,250 pounds, the lathe's substantial mass provides the rigidity and stability essential for maintaining tolerances during demanding machining operations. The machine is manufactured to rigid ISO specifications and features both inch and metric threading capabilities with a single switch lever for quick conversion. Standard features include comprehensive threading options without tool changes and reliable, consistent performance for continuous production work, making it ideal for shops requiring durable, high-capacity machining capabilities for large workpieces.
