CNC routers also known as computer numerically controlled routers are manufacturing machines that cut or rout patterns of various shapes made from metals, wood as well as plastics, foam, and many other materials. 

They can cut mechanically complex shapes more quickly and with more accuracy, precision, and repeatability than a human operator. They are able to greatly assist industries like cabinet manufacturing, signage as well as plastic fabrication among others. They can also take on huge tasks that require precise components quickly and efficiently. It is a good option to click to know about router sign-making machines.

CNC routers are available in standard sizes of tables ranging from 2 2' x 2' up or 5' x 10 Some manufacturers also make custom machines to 12 16 or greater. They've been in use for a long time but they've gained in popularity because of their improved speed and technological advancements.

CNC routers are able to cut and move in three directions commonly known as the X, Y Z axis. The X-axis is a left-to-right motion, whereas the Y-axis is a back-to-front movement. The Z-axis is upward or downward movement. Coordinates are entered into it by either the operator or by a software program, and the movement can be controlled through the self-contained control system.

A lot of routers come with the option of a hold-down system that makes use of pumps to draw air through the top of the router to secure the materials being routed. There is also an automated tool changer that makes use of robotics to swap between 10 different tools on a single task. 

The option to change tools can significantly increase efficiency and speed of work. Newer models have print-to-cut cameras that are mounted on routers. They also look for registration marks on the materials to guarantee the most precise routing.
