CNC milling machining is the process of cutting and drilling material (like wood or metal). A milling machine, regardless of whether it’s operated manually or through CNC, uses a rotating cylindrical tool called a milling cutter. It is held in a spindle and can vary in form and size.

The main difference between a milling machine and any other drilling machine is the ability to cut in different angles and move along different axes. For this reason, there are several kinds of milling machines, which are designated by the number of movement axes:

• 2-axis milling machines can cut holes and slots in the x- and z-axes. In other words, this machine will only cut vertically and horizontally (but only in one direction).
• 3-axis milling machines add the y-axis. This is the most common variety of milling machines. You can cut vertically and in any direction, but an object like a sphere will need to be done one half at a time. This is because, even with three axes, it’s not possible to cut from below.
• 4-axis milling machines are more complex because they add the ability to rotate the x-axis, similar to a lathe.
• 5-axis milling machines incorporate rotation in both the x- and y-axes. This is the most complete milling machine you can have. It allows you to shape bones, aerospace structures, car models, medical products, and pretty much anything else you can imagine.
• CNC milling machines can have any number of axes (2 to 5) but are operated through a computer. No manual operation required.

Types of CNC Milling Machining

Now we know that a CNC milling machine is any milling machine controlled through a computer. Yet, apart from axis classifications, there are still several types of milling machines, whether manual or CNC:

• Vertical mill: This 3-axis milling machine consists of a table, which acts as a work surface, below an arm, to which the spindle is attached. Both the table and the arm are connected to a vertical column, and the spindle is vertically oriented. Generally speaking, the table moves up and down along the z-axis to intersect the fixed arm. However, how the table and the spindle move in relation to each other depends on the type of vertical mill. In a turret vertical mill, the spindle is stationary and the table moves along both the x- and y-axes. In a bed vertical mill, the table can only be moved along the x-axis, while the spindle can travel along the length of the arm in the y-axis direction.
• Horizontal mill: This milling machine is similar to a vertical mill, except that the spindle is oriented horizontally instead of vertically. While generally considered less versatile than vertical mills, horizontal mills are better-suited to longer or heavy pieces of work. A universal horizontal mill has the additional capacity to rotate the table around the z-axis (making it a 4-axis milling machine).
• Knee mill: Any kind of mill where the table moves up and down the column according to an adjustable knee.
