Which CNC machine primarily uses a rotating spindle to cut material?

The correct answer is CNC Router. This type of CNC machine primarily utilizes a rotating spindle to cut through various materials, including wood, plastics, and soft metals. The spindle's rotation allows for the application of cutting tools that can shape and create designs from a solid block of material.

CNC Routers are commonly used in woodworking, signage, and various fabrication projects, showcasing their versatility in handling different materials with intricate patterns and details. The mechanism of the rotating spindle is central to the functionality of the CNC Router, as it enables precise cutting and is compatible with a variety of tool types for different applications.

While CNC Lathes and CNC Milling Machines also use rotating spindles for cutting, their operational focus differs. CNC Lathes primarily rotate the workpiece against a fixed cutting tool, which is more suited for cylindrical shapes. CNC Milling Machines utilize a rotating spindle as well, but they typically involve a different setup for handling parts, often moving the part under the rotating tool rather than using a moving spindle mechanism. In contrast, CNC Laser Cutters use a focused laser beam rather than a rotating spindle for cutting, operating on a fundamentally different principle.
