The difference between these two kinds of machine is the position of the axis. A horizontal machine moves side to side, while a vertical machine moves up and down.Vertical milling machines will have the table-mounted at a 90-degree angle to the zero-tilt position. However, a spindle on a horizontal machine will be mounted parallel to the table.

In VMC's, we can add 4th axis as well to increase the benefits of the VMC. Vertical Machining Center (VMC) with the 4th axis. If the 4th-axis is added in VMC, then the cutter can rotate around the x-axis which allows the VMC machine to drill holes in the front and back of the product. Hence, VMC that have an additional rotary axis are 4 axes ...

Advantages of a Horizontal Milling Machine. A horizontal mill operates in much the same way as a vertical milling machine does. However, horizontal mills have overhead arm supports and cutters that are arbor driven. These two features distinguish them from vertical models and add a bit more detail to the actual operation of the machine.
