Panel saw is any type of sawing machine that cuts sheets into size parts. Panel saws are used by cabinet shops to easily cut plywood and melamine sheets into cabinet components. They are also used by sign shops to cut sheets of aluminum, plastic and wood for their sign blanks. Panel saws typically fall into one of two categories: Horizontal and Vertical. Some higher end panel saws feature computer controls that move the blade and fence systems to preset values. Other lower end machines offer simplicity and ease of use.
