Circular Peeling machine is for slicing core veneer, surface veneer for plywood, and decorative surface veneer for furniture. It slices logs circularly and could not change the angel, so the grain is the same. This kind of peeling machine can have chuck or non-chuck.

Half round Peeling machine is for slicing decorative surface veneer for furniture.It involves attaching and rotating a half, third, or quarter of a log using a plate on a lathe. This method widens a thin timber by increasing the incision’s diameter. In some species of wood, half-round peeling machine is used to draw attention to the variety of grain. But, it can also be used to achieve a plain-sliced or flat veneer appearance.

You can change the angel of logs to change the grain of veneer. Half round peeling machine must have chucks. Therefore it is used for producing beautiful grain of veneer; the precision requirement of veneer thickness is higher.

Actually, these two kinds of machines slice veneer for different usage; It is hard to say which one is better.

Hope my comment is useful to you for knowing the function of machines.
