MACKINTOSH ROLL CNC MANUAL LATHES

Technical Description

The Mackintosh Roll CNC Manual Lathe is a heavy-duty engine lathe designed for large-scale machining applications. It features a maximum swing over bed of 125.98 inches (3200 mm) and an extensive distance between centers of 629.92 inches (16,000 mm), enabling it to accommodate very large workpieces. The lathe supports a maximum workpiece weight of up to 150 tons without requiring additional rests, underlining its capability for handling extremely heavy components. Its spindle operates at speeds ranging from 0 to 80 RPM, producing a torque of 1,336 kgf·m, which delivers substantial power for heavy cutting operations. The tailstock is equipped with a 19.68-inch diameter quill and a 17.71-inch stroke, suitable for stabilizing long workpieces during machining. Driven by a 150 HP main motor, the lathe is controlled via a Fanuc 21i CNC system, offering precise and programmable control for complex machining processes. The machine has a large 110.23-inch diameter faceplate and utilizes a robust 3-way bed design for enhanced stability and rigidity. Originally manufactured in 1995, this model was fully retrofitted in 2012 to integrate modern CNC control technology, improving its operational efficiency and versatility. The Mackintosh Roll CNC Manual Lathe is engineered for high-capacity roll turning, engine lathe tasks, and heavy-duty industrial machining requiring precision and strength.
