Why use Rotoplane?
To process short parts: On the Rotoplane, the distance between the pressure shoe and the hold-down platten, after the milling knife, is less than 1″. Parts as short as 4″ long can be run without any problems. Limitations on Running Short Parts: The distance between the chip breaker and the pressure shoe on sanders and knife planers can be as much as 8″. This makes it virtually impossible, not to mention dangerous, to run parts shorter than 8″
Quality Glue-Joint Strength:
The shearing action generated by the disk’s milling action, creates a porous wood surface. This allows the glue to penetrate the wood surface, and results in a superior glue-joint. Poor Glue-Joint Quality: Sanding/grinding the wood breaks the wood fibers. Gluing up on broken fibers creates a weak joint. Knife-planing can create a surface which is glass-like; this type of surface does not allow the glue to penetrate the wood. Both methods result in a poor quality of the glue-joint.
Planing Thin parts:
The Rotoplane system can be used to planning of thin parts. Parts as thin as 1/32″ can be planned without any snipe on the leading or trailing ends of the parts. :Limitation of running thin parts using the conventional method When thin parts are run through a conventional planning machine, there is always a tendency for the leading and trailing ends to have snipe. This is due to the distance between the chip breaker in front of the head and the hold down shoe after the planner head. No vacuum bed is required as the part which is being fed through the machine is captured between the feed belt and the platten/disk which is located in the centre of the rotor.
The machining action which occurs during milling is from right to left, and minimal force is exerted on the part being machined. This makes the Rotoplane planer extremely safe to operate. Safety Concern: The direction of the force, exerted by either a cutter head or a sanding belt, is directly back toward the operator who is feeding the parts. This is extremely dangerous for the machine operators.
Low Tooling Costs:
The Rotoplane system can run on one set of knife inserts for up to 3 months at a cost of less than $100/set. High Belt/Tooling Costs: Belt costs can run as high as $100/belt, and a belt might only last one day.
Low Energy Costs:
Due to the momentum generated at the cutting disk (mass motion), less amps are drawn by the motors. This results in lower energy costs. High Energy Costs: A conventional cutter head generates little mass motion and high energy costs are the results. A great deal of energy is also consumed by the inefficient grinding action of a sanding belt.
