The Nova S520 is a heavy duty, 20” planer designed to meet the needs of the most demanding environments. It features a monoblock base, work table with support rollers, and a Tersa cutterhead.

Monoblock technology is used in the design and fabrication of this base. The solid, welded base undergoes a treatment called normalization which stabilizes the metal and assures exact tolerances. All machine mechanisms are mounted, aligned, and referenced to the base. This design is vastly superior to frames that are bolted together and have no true reference point.

All SCM planers use four jack screws with acme style threads and dust covers for maximum table support. In addition to providing a stable lifting system which eliminates sniping, the acme threads greatly increase the longevity of what is normally the most common wear item on planers. Through a patented design, there is a special bushing between the drive chain, and sprocket which doesn’t allow any pressure from the chain to reach the jack screw, thus pushing the machine’s longevity to the extreme.

Used when planing raw, uneven lumber, the work table support rollers allow irregular material to be planed that would not feed on a standard table. When the material has been planned flat on one side, the rollers can be lowered to allow a clean pass on the other side.

SCM “T” models include the quick change knife heads by "Tersa." This cutterhead eliminates the necessity of gauging the knives each time to ensure proper setting position. The Tersa knives automatically reference into position when the head is turned on. Removal of the knives is as simple as tapping down the wedge blocks and sliding out the knives. Since the knives are two-sided, they can be flipped over, reinserted, and used again.
