The Cutting Tool that is mounted to the CNC Machine dictates what type of CNC machine it is. CNC Routers and CNC Mills use Routers or Spindles. CNC Plasma machines use plasma cutting tools, while CNC Laser machines use a wide range of different laser tools. There are other tools such a caulking tools and glue guns often used in sign making. Automated soldering tools are also used for creating PCBs and electronics that require the precision that only a computer-controlled machine can offer.
Whether you choose a router or a spindle, you will need a mounting bracket to attach the tool to the CNC machine. There are several sizes to choose from and also a universal mounting bracket that can be used to mount many different shapes and sizes.
