Description:

The S520 Nova S 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 “SHELIX” cutterhead.

• Sliding tenoning table with miter unit and clamps
• 1 1/4 Inch interchangeable spindle
• 5 Spindle speeds from 3,000 to 10,000 rpm
• Reverse rotation switch
• 5 Table insert rings
• Mechanical digital readout of spindle height
• Foot pedal control of mechanical brake and spindle lock
• Magnetic starter with overload protection
• Low tension circuit (110v by transformer)
• Tool kit with spare V-belt
• Wooden fences
• Adjustable fence and guard assembly

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.

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 planed flat on one side, the rollers can be lowered to allow a clean pass on the other side.

The “SHELIX” cutterhead combines several technologies into one super efficient cutting tool. First, the knives are mounted in a spiral, staggered manner to improve the efficiency of the chip extraction. The Helix design also assists the chip flow. Finally, the shear provides a clean cutting action.

• shear on each knife for true helical cut
• clearance between knives for chip flow
• inexpensive 4 sided replaceable carbide
• unbelievably quiet
• replace only damaged or dull knives
• no grinding necessary
• all machined from one length of bar

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.

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.
