Tips when Buying a CNC Milling Machine

Aug 6, 2008
CNC machines have revolutionized the entire manufacturing industry, no longer do you have to spend ages setting up a machine. A computer is able to control it for you. These CNC machines are often too expensive for private use, however it is possible to buy smaller machines at a fraction of the cost.

How do CNC Machines Work

CNC machines are used in a number of industrial applications, from metal fabrication businesses to woodwork workshops. CNC routers can be used in order to drill accurate holes. Some CNC machines are capable of a number of different tasks as they can use different tools. These save a lot of time and are also very accurate.

CNC actually means Computer Numerated Control. This was developed in the 70?s. Before use the machines must be programmed, however once it?s set up it can continue doing the same job all day long. The back stops and guides will continually adjust themselves to each operation, this means you do not need to continually adjust the machine for each stage.

CNC routers can be programmed using a computer program to drill holes in specific locations without anybody having to do anything other than supervise the machine. You need someone to set up the machine, however after that you only need someone to push buttons! These machines are great for jobs that are normally labor intensive or require accuracy.

Types of CNC Machines

CNC is a type of technology which is available in a number of different machines. It is for example available in a lathe. This is very useful when cutting wood. Most of these lathes will be able to operate in a number of different modes, from manual to CNC. This allows you to use the one machine in different ways.

The best mills are thought to be Bridgeport machines. Many industries require mills, from small shops to large businesses. Bridgeport mills are very reliable and should last for a very long time. These mills are however very expensive, and are out of most people?s reach!

CNC mills are specialist equipment, they use robotics alongside computer programming in order to get accurate results. These are more accurate than a mere mortal could ever hope to achieve! Bridgeport mills are commonly used to manufacture parts for the airline industry as they are so accurate. The machines can change tools themselves so that they can do a number of different processes without having to move to different machines.

You can also purchase CNC engravers which can engrave a number of different materials such as stone, glass wood, metal and composites.

Buying Used CNC Machines

CNC machines are extremely expensive, especially if you buy brand new ones. This makes it impossible for many people to afford them, however you could consider buying used CNC equipment. By buying these machines you can normally save 50% or more on the price of a new machine. You must to be careful when you are buying used machines, otherwise you could be buying into trouble.
