CNC machines can be a lifesaver in an industry setting. They speed up work in those tedious jobs that seem to never end. Although they can be a bit pricey new for solo use, you can put one to work on your wood working room for around half the price if you buy used.
About CNC Machines - How Do They Work?
CNC machines, aka Computer Numerated Control machines, are mechanical drillers, in a nutshell. When they are programmed properly, the CNC equipment can produced drilled holes in record time. This technology first hit industry in the 1970s and turned manual labor on its head. Production times were reduced significantly by this milling machine.
The reason CNC machines were so revolutionary is because they could complete the work of many human drillers in record time, and the work they were produced all but eliminated human error. Many industrial industries rely upon CNC equipment every day.
CNC Machine Types
If woodcutting is your thing, a CNC lathe is the way to go. This machine can cut your wood in any width and shape you want with minimal error and incredible speed.
For a milling machine, a Bridgeport machine is the best choice. Although these machines are extremely pricey, they can also make milling significantly more productive.
CNC machines can also be used for engraving. They can engrave on nearly any surface, and with the right programming, they can engrave a huge variety of different fonts, letters, and designs.
CNC Machines on a Budget
These machines might be ultra productive, but most individuals could never make enough use out of them to justify their hefty price tag. However, if you have a small but growing business, a CNC machine could take you to the next level. Buy used, save big time, and watch your profits grow.
Refurbished CNC machines are even cheaper than ones that are merely used but have never had any problems. A refurbished machine is one that has been repaired by a professional, and the extent of the repairs will impact the price you can get on one. You don't have to fear these refurbished machines because they have had a few problems in the past. In almost every case, a refurbished machine will come with a warranty that will give you peace of mind about your investment. Shy away from those "buyer beware," no warranty type of packages. A good refurbisher won't mind backing up their own work.

CNC Machines
What is a CNC Machine? CNC stands for Computer Numeric Control. Sounds complicated, but it isn’t. 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. It’s a machine that drills holes. But before you can drill the hole, you have to loosen the chuck, install the correct drill bit, drill the hole in the correct place, turn off the drill, and remove the drill bit. Manually, this could be time consuming and cause fatigue over the course of numerous parts. This is a simple example, but throw in some lathe or milling machining and you have a greater chance for error.
With the CNC machine, all of this drilling can be done automatically instead of the manual process listed above. Machining has to be precise, and whether you use a CNC lathe or milling machine, you have to make sure the part is right. The computer takes a lot of the guesswork out of the machining of these parts. 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 would think. The operator has to enter a set of instructions. The programming uses about 50 words and tells the machine how fast, how deep, and location for machining.
What can you do with a CNC machine? In manufacturing, you can use this tool for milling, drilling, reaming, boring and counter boring. You can also groove and thread parts in a CNC turning center. You may have several setups including CNC lathes, CNC drill and tap area, CNC milling, or even CNC grinding.
EDM (electrical discharge machining) can also take advantage of CNC operations. EDM can be either vertical or wire. A vertical EDM machine uses an electrode to make a cavity for a plastic injection-molding machine. A wire EDM machine uses a wire to cut metal for a tooling operation for fabrication. EDM is more closely related to making tooling for other machines, people often overlook the use of CNC with these machines.
CNC machines can also be used with routers in the wood industry. CNC can also be used with lettering and engraving.
I hope this gave you some basic information about what a CNC machine is and what they are used for.
