The most common types of CNC machining tools are vertical milling machines, lathes, and drilling or boring machines. Other types include EDM machines, laser cutting machines, and water jet water profiles. These are just a few examples used in the manufacturing industry today.
The CNC acronym means “computer numerically controlled.” In this tool, the computer or “controller” drives the machine according to the G-code instructions. The machine is designed to perform repetitive tasks quickly at high speeds. Common tasks include cutting, grinding and drilling.
The manufacture of modern CNC machining tools began as early as the 1940s by John T. Parsons to produce wing parts for the United States Air Force. Today, the range of products made with this machine is very wide. CNC machining tools produce specialized parts for the machinery and automotive industries worldwide. Other types of industries that use CNC machining tools are wood and granite or stone industries.
The main component of CNC machining tools is the machine control unit. This unit reads and parses instructions, generating axial commands and feeds motion feeds to circuits that drive axial mechanisms. It also controls the function of the spindle, coolant and change tool. Other components of CNC machining tools are program input devices, which install parts programs into CNC controls, and parts programs, which control the movement and function of machines.
Various types of machinery use CNC as a controller. Training or turn center is a common CNC machining tool. This type of machine is capable of performing various operations of latex cutting automatically. CNC laser cutting machining tools are another type, and use focused light beams to cut various materials.
CNC EDM machining tools operate using thin wire as an electrode. The resulting erosion caused by the bow is what is cut. CNC controls the movement of the table, as the wires remain in motion during operation.
Machining center is the latest CNC machining tool. It is capable of performing various tasks such as milling, boring and drilling in a single setup. Pallets or work tables automatically change the required work pieces. The machining center automatically changes the tool head to perform specific tasks as needed.
