What is CNC router? A CNC Router is a machine that has a bunch of different cutting bits that allow it to shape and cut a wide variety of different materials. All of this is controlled by a computer system.It can cut or shape metals as aluminum,stainless steel,and plastics. The computer will command the machine what tool head to use and what path that tool head is supposed to take all of that according to the computer programming.The coordinates that the tool head is told to follow are sent to it from a separate CAD (computer-aided design) programming. This allows the machine to be able to do big sweeping cuts or fine detail routing.Almost anything that you can draw with CAD can be uploaded to the CNC to be routed.A CNC router can reduce waste, frequency of errors, and shorten production time and raise efficiency of production. It can cutting out many machinable parts as complex shapes, and big signs.It is convenient for the large quantities of parts and complex to process.
