<p>The working principle of a CNC turning machine revolves around rotating the workpiece while the cutting tool remains stationary. The turning process starts by securing the raw material (typically in cylindrical form) into a rotating chuck. The cutting tool then removes material from the workpiece as it spins, shaping the material into the desired profile.</p><p>CNC turning machines use pre-programmed instructions to control the movement of the cutting tool. These instructions are written in G-code, a programming language that dictates how the machine moves, the speed of rotation (RPM), and the depth of the cut. This precision-controlled process ensures that each part meets exact specifications with minimal variation.</p>
