The PR-10500-4CNC 4 roll plate bending machine is the ultimate in production plate rolling. It has the same bones as its sister models the PR-10500-4 and PR-10500-4NC but incorporates a CNC touchscreen controller that has been specially designed for Baileigh Industrial plate rolls. When designing a CNC for a bending machine, you will encounter considerable challenges, the main one is the tolerance of the yield point of the various materials that are bent: lots of material nominally "identical" to each other, often present results bending quite different.
