A CNC (computer numerical control) machine with a linear slide is a type of machine tool that uses computer-controlled operations to shape and finish materials. The linear slide refers to the design of the machine’s moving parts, specifically the linear guides or “slides” that support the movement of the cutting tool in a linear or straight line movement. This design allows for greater stability and precision in the cutting process and is often used in manufacturing of aerospace, automotive, and medical components. The linear slide is mostly used in milling and drilling operations.
