Rotoplane Rotary planing machines are the modern way to calibrate and prepare wood products for gluing or finishing. These versatile machines offer improved quality, productivity, and a significant cost savings when compared to conventional planing. Rotoplane machines feature a unique, patented planing head, which moves in horizontal rotation rather than vertical rotation as with the conventional planer heads. This is an important difference that offers many advantages. With the rotary planing, grain direction in the work piece is not longer a concern. Neither are resinous, knotty, or wild grain woods. You can now process cabinet doors, glued panels, can complete frame assemblies without fear of surface tear out. In addition, the shearing action of the planing head leave a smooth porous surface that is perfect for gluing . It is neither too slick, as with planing nor torn as with sanding. The result is tighter, stronger joints. The unique rotory head employs durable multi sided carbide blades which can be rotated 4 times.
