Different from drill press, where in the work piece is held fixed and the drill is the one to move vertically to make a way to the material, milling too involves movements of the work piece adjacent to the rotating cutter, but it is capable of cutting to cut up the sides along with the tips. The movements of the work pieces and cutters are accurately controlled, usually via the precision ground slides along with the lead-screw or with analogous technology. Milling machines can be operated manually, by mechanical automation or by digital automation via the Computer Numerical Control or CNC.
Be sure that you understand the benefits of having CNC milling machines before you start purchasing them.
There is a variety of different tools that can be used with this type of machinery. In the US, the most common CNC miller tooling is the CAT tooling; however, now a better alternative called BT tooling as raised the bar. BT tooling can be easily confused with CAT, so be careful.
Most of these CNC milling machines can perform versatile cutting and drilling operations - There are several types of these CNC machining centers that are well-known as multiaxis machining centers including 3-, 4- and 5-axis machines. Certainly, those machines which have the higher number of axes are cost higher than lower numbered axes because these machines are able perform intricate parts production. Thus, normally large scale manufacturers own 4-and 5-axis machines as both machine types are able to boost their productivity and profitability over a certain period of time.
Once all of the axes were in union with one another, very complicated geometries are able to be made easily with this kind of machine. However, the ability to program the complicated geometry is beyond the most operators' ability. For that reason, 5-axis mill machines at all time is programmed by the CAM.
