PROKING PA-50 MANUAL LATHE

Technical Description

The PROKING PA-50 is a heavy-duty manual lathe engineered for large shaft turning and heavy machining tasks. It features a substantial **swing capacity of 50.4 inches** over the bed and a long **distance between centers of 118.1 inches**, accommodating lengthy workpieces. The lathe is equipped with a **22-inch spindle bore**, enabling it to handle very large diameter shafts or hollow workpieces. Powered by a robust **50 hp dual-voltage spindle motor**, the PA-50 delivers strong cutting force suitable for demanding industrial applications. Built on a precision **two-shear bed with hardened and ground ways**, the machine ensures maximum rigidity and vibration damping for high accuracy. A **pressurized one-shot lubrication system** services the cross slide and carriage, enhancing longevity and smooth operation. The spindle nose typically conforms to A2-32 standards, facilitating compatibility with various tooling setups. The lathe's heavy construction, often weighing up to 31,000 kg, provides stability critical to precision machining. Additional standard features include a **MT #6 dead center** and a **two-speed tailstock quill** for flexible support during turning. The PA-50 can be customized with optional features such as programmable tailstocks, C-axis milling capabilities, high-pressure coolant for deep bore machining, and fixed or traveling steady rests to support long or heavy workpieces. Designed for oil, gas, subsea, and heavy industry sectors, the PROKING PA-50 combines large capacity, robust construction, and precise engineering to reliably perform complex and heavy machining operations.
