Horizontal milling machines feature a similar design in which a spindle containing a rotating cutting tool presses against a workpiece to remove material from the workpiece. If you need a machine that offers high output and a quick turnaround time, a horizontal milling machine can cut faster than a vertical mill, and may even be able to make more than one cut at a time. This speed comes at no sacrifice to precision, so they are a powerful tool for detailed or long-running projects.
