MONARCH LATHES 528 MANUAL LATHE

Technical Description

The Monarch Lathes 528 is a precision manual engine lathe engineered for general-purpose machining operations. This machine features a 27.9-inch swing capacity with a maximum swing over the cross slide of 17.3 inches, allowing for the processing of medium to large diameter workpieces. The lathe is equipped with 39.4-inch centers, providing substantial length capacity for extended workpieces. The spindle bore measures 4.1 inches, accommodating various tooling and workpiece mounting configurations. Powered by a robust 20.0 horsepower motor operating at 1,400 RPM, the Monarch 528 delivers adequate torque and cutting force for demanding production work and heavy-duty finishing operations. This power output places it in the upper range of comparable mid-sized manual lathes, enabling efficient material removal rates and consistent surface finish quality. The lathe's construction emphasizes robust cast iron construction typical of Monarch's universal center lathe design philosophy, ensuring precision, high performance, and rigidity during operation. The 528 model is well-suited for machine shops requiring capability to handle varied workpiece geometries and materials. Its specifications make it ideal for threading, boring, turning, and facing operations across ferrous and non-ferrous materials. The combination of adequate spindle speed, substantial horsepower, and generous swing capacity positions this lathe as a versatile workhorse for both production and prototype machining applications in industrial settings.
