Computer Numerical Control (CNC) machines are automated milling devices that make industrial components without direct human assistance. They use coded instructions that are sent to an internal computer, which allows factories to fabricate parts accurately and quickly. There are many different types of CNC machines, ranging from drills to plasma cutters, so they can be used to make a wide variety of parts.
CNC Computer Numerical Control machines are widely used in manufacturing industry. Traditional machines such as vertical millers, centre lathes, shaping machines, routers etc.... operated by a trained engineer have, in many cases, been replaced by computer control machines.
CNC lathes rotate a Material along an axis and remove material from the workload with each pass. Material that are modified by CNC lathes emerge with symmetrical and cylindrical shapes. CNC lathes can be programmed to create an unlimited number of shapes and designs into objects.
A CNC router is attached to a table and uses computer programming to remove material from a piece of wood or metal in a specific pattern or shape. The router is usually attached to a three or four speed motor system. The four motor systems provide additional speed and increased accuracy. A recessed door hinge in a door frame is an example of the type of work done by a router.
CNC routers designed for use with wood typically spin at a rate between 13,000 and 24,000 revolutions per minute (RPM).
cnc milling machine
A CNC (Computer Numeric Controls) milling machine uses CAD/CAM cutter paths to cut away metal blocks into the various parts of an injection mold and then add the cavities and ejector pin holes.
