What is a CNC router primarily used for?

A CNC router is primarily used for cutting and engraving various materials, with a strong emphasis on wood. This machine operates by using computer numerical control technology to direct the movements of the cutting tool with precision, allowing it to create intricate designs, patterns, and shapes in wood and other materials like plastics and soft metals. The versatility of a CNC router makes it popular in industries such as furniture making, sign-making, and crafts, where detailed designs and high levels of accuracy are crucial.

Welding metals, 3D printing complex shapes, and drilling holes in hard surfaces are functions associated with different types of machinery that are not designed for the specific precision woodcutting and engraving tasks that a CNC router excels at. Each of these other operations requires distinct methodologies and tools not found in a CNC router, which focuses primarily on the cutting and engraving processes.
