CNC (Computer Numerical Control) machine tools are automated devices that control machining processes through computer programming. Known for their high efficiency, precision, and stability, they are widely used across industries such as aerospace, automotive, mold making, electronics, medical, and energy. With the rise of Industry 4.0 and smart manufacturing, CNC technology continues to evolve toward multi-axis machining, intelligent control, remote monitoring, and integrated processes. This widespread adoption not only enhances manufacturing performance but also reshapes the workforce, shifting traditional manual skills toward digital operation and system integration—bringing greater production flexibility and competitiveness to businesses.
