SUMMIT 22-4x120 MANUAL LATHE

Technical Description

The SUMMIT 22-4x120 Manual Lathe is a precision-engineered heavy-duty machine designed for versatility and high-performance machining. It features a 21.97-inch swing over the bed and a 12.5-inch swing over the cross slide, enabling machining of large diameter workpieces with precision. The lathe accommodates workpieces up to 120 inches between centers, suitable for long components. Its spindle bore measures 4.13 inches to allow substantial bar stock or tooling through the spindle. Powered by a robust 15 HP motor, the lathe operates at a maximum spindle speed of 1,250 RPM, balancing power and control for handling heavy chip loads and diverse materials. Constructed predominantly from cast iron with hardened and precision ground bedways, it ensures rigidity, vibration dampening, and long-term accuracy. The heavy machine weighs approximately 8,800 lbs and spans dimensions of 183 inches in length, 36 inches in width, and 54 inches in height, reflecting its industrial capacity. The lathe includes a quick-change gearbox for thread cutting (inch, metric, module, and diametrical pitch) without the need for change gears, enhancing workflow efficiency. Additional engineering features provide ISO compliance, built-in safety mechanisms, and ease of operation, making it suitable for demanding metalworking applications requiring fine finishes and precise control. This combination of rugged construction, substantial capacity, and precision controls classifies the SUMMIT 22-4x120 as a reliable and versatile manual lathe for professional machine shops and industrial manufacturing.
