COLCHESTER COMBI K4 CNC LATHES

Technical Description

This CNC lathe features a **4-inch bar capacity** and operates with **2 axes (X and Z)**, providing precise control over diameter and length during machining. It is powered by a robust **25 HP motor**, enabling a **maximum spindle speed of 1,800 RPM** for efficient material removal and surface finishing. The machine supports a **maximum turning diameter of 21.8 inches** and a **swing of 22 inches**, accommodating moderately large cylindrical workpieces. It allows for machining lengths up to **78.7 inches**, offering versatility for longer parts. Equipped with a **tailstock**, it provides additional support for extended workpieces, enhancing stability and accuracy during turning operations. Control is managed via a **Fanuc CNC system**, renowned for high precision, repeatability, and user-friendly programming, essential for complex and consistent part production. This combination of specifications makes the lathe suitable for producing medium to large-sized cylindrical components with high precision in industrial and manufacturing settings. The 2-axis configuration supports linear motions in both the X and Z directions, ideal for turning, facing, threading, and other basic lathe operations, while the 25 HP power ensures capability for tougher materials and heavier cuts. The swing and turning diameter define the maximum part size the lathe can handle without interference, and the inclusion of a tailstock aids in machining long or slender parts safely. Overall, this machine provides a balance of power, size, and CNC control for efficient, accurate turning tasks.
