The CNC mill is one of the most efficient ways to manufacture metal parts. The widely used CNC milling machines are the horizontal machining center and vertical machining center. Types of horizontal and vertical CNC machining centers range from 3-axis benchtop CNC mills to 5 axis CNC mills, short to long travels, and fast to heavy-duty RPM spindle speeds. Some of the top mill machine tool manufacturers include DMG Mori Seiki, Doosan, Daewoo, Haas, Mori Seiki, Hurco, Makino, Mazak, Milltronics, Okuma, Samsung, OKK and other brands.
