NOVA S 520 T
20" Tersa planer
The Nova S 520 T 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
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.
