What is a CNC machine? CNC stands for computer numerical control. Sounds complicated, but it’s not. Years ago, it was just NC, or numeric control. Since, they’ve added computers to control the machine.

In the simplest of terms, think of a drill press. This is a machine which creates holes. But before you drill the hole, Unscrew the cartridge, install the correct drill bit, drill a hole in the right position, stop the drill and remove the drill. Manually, this can take a lot of time and cause fatigue over the course of numerous parts. This is a simple example, but toss in certain lathe or milling and You have a greater chance for error.

CNC, all this drilling can be done automatically instead of the manual process listed above. Processing must be accurate, and whether you use CNC or milling machine, you should make sure that part is right. The computer takes much of the guesswork out of processing these items. In fact, a CNC programmer can sometimes get bored watching the machine do ALL the work.

But there is more programming for the machine than you might think. The operator must enter a set of instructions. The programming uses about 50 words and tells the machine how fast, how deep, and location for processing.

What can be done on the CNC machine? In production, you can use this tool for milling, drilling, reaming, boring and counter boring. Also you may groove and thread parts in turning centers with CNC. You can have multiple installations, including lathes CNC, CNC drill and tap area, CNC milling, CNC Grinding or even.

EDM (electrical discharge machining) can also take advantage of CNC operations. EDM can either be vertical or wire. A vertical EDM machine uses an electrode to make a cavity for plastic injection moulding machine. Wire EDM machine uses a wire to cut metal for surgery with the tool for manufacturing. EDM is more closely related to tooling for other machines, people often overlook the use of CNC with these machines.

CNC machines can also be used with routers in the woodworking industry. CNC can also be used with embossing and engraving.

I hope this has given you some basic information about what is CNC and what are they used for.
