Technical Description

The PROKING PB-45 Manual Lathe is a heavy-duty machine engineered for demanding turning applications, featuring a robust one-piece bed with hardened and ground ways for exceptional rigidity and precision. With a swing of 45.87 inches (1,165 mm) over the bed and 33.07 inches (840 mm) over the cross slide, it accommodates large workpieces with ease. The distance between centers is adjustable from 1,500 mm to 12,000 mm in 40-inch increments, providing flexibility for a wide range of component lengths. The lathe is powered by a dual-voltage spindle motor rated at 30 horsepower (standard), with options available up to 50 horsepower for more intensive cutting tasks. The spindle bore measures 6 inches (152.4 mm), suitable for large-diameter bar work, and the spindle nose is compatible with A2-11 to A2-40 standards. The machine incorporates a 6-way rapid traverse and power feed to the top slide, enhancing productivity and operator convenience. All gearboxes are fully enclosed and support both inch and metric threading, with a digital readout for accurate positioning. The tailstock features a quill diameter of 145 mm (5.7 inches), travel of 200 mm (7.87 inches), and an MT#6 taper. The PB-45 also includes a pressurized one-shot lubrication system for the cross slide and carriage, ensuring consistent performance and reduced maintenance. Designed for oil country and heavy industrial use, this lathe delivers reliable, high-precision results for large shaft and complex component machining.
