KINGSTON CJ-2240 CNC LATHE

Technical Description

This 2-axis CNC lathe is a versatile mid-range turning center designed for precision machining of cylindrical components. With a 22-inch swing over bed and 40-inch maximum machining length, it accommodates a wide range of workpiece sizes, making it suitable for both small batch and production runs. The machine features a 3.125-inch bar capacity, enabling efficient automatic or semi-automatic feeding of material stock. Powered by a robust 20 horsepower spindle motor, the lathe delivers consistent cutting performance with a maximum spindle speed of 2,400 RPM, ideal for roughing and finishing operations on various materials including steel, aluminum, and cast iron. The inclusion of a tailstock provides essential support for longer workpieces, enhancing machining stability and accuracy during extended turning operations. This 2-axis configuration—controlling X (diameter) and Z (length) movements—executes fundamental turning, facing, and threading operations with repeatability as precise as ±0.0005 inches. The machine offers flexible control options through industry-standard CNC controllers, including Fagor 8060FL, Fanuc 0iTF, or Siemens 828D, allowing operators to select systems compatible with their existing shop infrastructure. These controls enable programmable tool paths, automatic feeds, and precise dimensional accuracy, eliminating manual operation variables. This lathe is well-suited for manufacturing applications requiring consistent quality and efficient production, from automotive components to general industrial parts, making it an excellent choice for job shops and manufacturing facilities seeking reliable, computer-controlled turning capability.
