Vertical Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Vertical machining occurs on a vertical machining center (VMC), which employs a spindle with a vertical orientation. With a vertically oriented spindle, tools stick straight down from the tool holder, and often cut across the top of a workpiece.

Difficulties in the starting of vertical turbines have also hampered development, believed until recently to be incapable of self-starting [2]. However, the VAWT requires no additional mechanism to face the wind and heavy generator equipment can be mounted on the ground, thus reducing tower loads. Therefore, the VAWT is not completely

between vertical mills and ball mills arises from differences in the frequency and energy intensity of ball collisions. The higher efficiency of the vertical mills is due to the higher frequency of lower energy impacts and, by the same token, lower frequency of higher energy impacts when compared to conventional ball mills (Mazzinghy et al., 2013).
