What You Should Know about CNC Milling

The term CNC, or Computer Numerical Control, has been around since the mid-1900s.  Milling machines, however, has been used since the Industrial Revolution well before that.  Even though these terms have been around for a while, many people are still confused about the role of CNC milling and how it is different from CNC machining.  There are a few things you should know about CNC milling to help you better understand the technology used in the process, what it creates, and how it can help you or your business.

Not All CNC is Milling or Machining

Many people assume that the words 'CNC' and 'milling' and 'machining' are exclusive to one another, but this is inaccurate.  CNC is the technology that is used to operate the mill, but CNC can also be used in many other methods as well, such as 3D printers, lathes, and many other machines.  When someone talks about CNC technology with you, be sure to clarify the types of machines they are using with the technology.

Common Mills are Vertical and Horizontal

The type of mill used can be either horizontal or vertical.  These terms refer to the axis of movement for the mill's cutter.  When you observe the mill close-up, you can take notice of these differences.  Vertical mills cut back and forth in a line that is parallel to the workbench.  Horizontal mills, on the other hand, will cut along an X-, Y-, or Z-axis.

Each Mill Type Has Different Advantages

In addition to horizontal and vertical mills, there are a few other types of mills commonly used in our industry.  Vertical mills, for example, are typically smaller and more affordable than horizontal mills.  This is typically because horizontal mills are used for large-scale projects that are for needed industrial settings.  

Most Milling Machines Have Three Axes of Movement

Most milling machines will operate using three axes of movement, including X-, Y-, and Z-axes.  CNC machining, on the other hand, have an even greater range of movement than CNC milling machines do.   These can be flipped, which adds an A- and B-axis of movement.  Once you begin to add more axis of movements, you will also increase the price of the machine you are using.  

Milling Machines Can Also Be Operated Manually

Even though we use CNC milling to perform our tasks, milling machines can also be operated manually.  The main difference between milling machines and other cutting machines is that milling machines are capable of cutting in different angles and along different axes, which provides custom cuts for machine and manufactured parts.

These are a few things that will help you better understand CNC milling and how it can help you or your business.  CNC milling has become an extremely popular method of creating custom cut parts for manufacturing.  Contact Limea Precision to hear how we can help you with your CNC machining and CNC milling projects today.
