What is CNC Router
A CNC router is a computer controlled tool for cutting various type of product such as wood, plastic, aluminum, steel and other kinds of metal. CNC routers comes in many configurations including the small home style known as “Desktop CNC Router” to the larger ones known as “Gantry CNC Routers” which are used on boat making facilities. Though there are many configurations, still most of the CNC routers have a few specific parts in common, likes CNC controller, one or more spindle motors, AC inverters, and a table. Generally CNC routers are available is 3 axis and 5 axis formats.
CNC router works like a printer. Work is composed on a computer and then the design or drawing is sent to the CNC router for the hard copy. As CNC routers are run and controlled by a computer, coordinates are uploaded into the machine controller from a separate program. There are basically two programs used, one to make designs and another to upload designs to the machine and run it. CNC routers can be run and controlled directly by manual programming, but the full potential of the machine can only be achieved if they are controlled from the file created by the CNC software (such as “CAD/CAM”).
Advantages of CNC routers:
1) Can be very useful when carrying out identical, repetitive jobs.
2) Produces consistent and high quality work and improves factory productivity.
3) Can reduce waste, frequency of errors and the time the finished product takes to get to market. For Example: CNC routers can perform the tasks of many carpentry shop machines such as the Panel saw, the spindle molder, the tunnel boring machine, and can also cut mortises and tennons.
4) Gives more flexibility to the manufacturing process.
5) Can be used in production of many different items, such as door carvings, interior and exterior decorations, wood panels, sign boards, wooden frames, moldings, musical instruments, furniture manufacturing and many more.
6) Can also make thermo-forming of plastics by simply automating the trimming process.
