CNC milling stands for computer numerical controlled (CNC) machining. Milling is similar to both drilling and cutting and equipped to achieve many of the operations performed by drilling and cutting machines using a rotating cylindrical cutting tool. However, the difference between a conventional drilling machine and a milling machine is that the latter make use of a cutter that can move along multiple axes, and can create a variety of shapes, holes and slots. Unlike the drilling machine the work piece in milling machine moves across the milling tool in different directions.
CNC Mills Classification:
CNC milling machines are classified on the basis of the number of axes on which they operate. The axes are labeled with various letters such as X and Y wherein X and Y designate horizontal movement of the work piece. Additionally, Z represents vertical movement while W represents diagonal movement across a vertical plane. Besides, some machines offer from 3 to 5 axes that provide performance along at least the X, Y and Z axes. The more advanced CNC milling machines such as 5-axis milling centers make use of CAM programming for ideal performance due to the complex geometries involved in the process. CNC mills are very useful in producing shapes that would otherwise be nearly unattainable using manual tooling methods.
Why CNC milling machines?
CNC mills are widely used to produce wide range of components in a cost effective manner. It supports an array of manufacturing needs that is suitable for the large productions. Therefore, it makes an ideal choice for prototyping, and short-run production of complex parts along with manufacturing of unique precision components.
How to buy the best CNC milling machine?
There are number of CNC mill providers available in the market making it a tough choice to pick the right provider. Nevertheless, look for the trusted name in the business that is renowned for its best machine performances. Compare the prices and opt for the best deal available on the market. There are many providers that offer CNC milling machines at affordable prices. However, thoroughly examine the machine before you make a final decision.
