The Nova S 520 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 Base
Monoblock technology is used in the design and fabrication of this base. The solid, welded base undergoes a treatment call 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.
Table Lifting System
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.
Work Table Support Rollers
Used when planing raw, uneven lumber, this feature allows 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.
Planer Head Assembly
The SCM feed system includes a powered sectional steel infeed roller and powered rubber outfeed rollers. This combination helps ensure feeding of parts with variations up to 6mm in thickness. Anti-kickback fingers and a sectional chip breaker are also part of the feed section and provide both safety and a quality finish.
Tersa Cutterhead
The quick change knife heads by "Tersa" 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.
One Machine for Every Requirement with the Interchangeable Rollers. Quick and easy changeover of the rollers that allows the operator to configure the machine drive function in case of special requirements such as minimum removal of fine wood and/or batches where multiple pieces of different thicknesses are processed.
Perfect Finish with the Feeding Rollers on Connecting Rods. The stopping of the work piece and the presence of notches on its surface are eliminated due to the movement system on all three rollers that allows their vertical displacement by rotation and the best linear feeding.
Sturdy Structure with Precision when Moving the Worktable
The 4 screws with a large diameter combined with the 2 side linear guides ensure worktable stability eliminating the necessity of locking in position. The integrated protections guarantee high precision and reliability over time.
