Four Knife Cutterhead with Integral Micrometer Type Knife Raising Screws

The four knife cutterhead of high carbon steel is 25" long and ha a 5" cutting circle. The 5/32" x 1-1/4" x 25" knives are of high speed steel and can be quickly adjusted with the micrometer type knife raising screws machined integral with the cutterhead. The cutterhead can be quickly stopped with a convenient brake.

1. Sectional Chipbreaker Mounted Concentrically with Head

A sectional chipbreaker of 2" ductile iron sections is concentric with the cutterhead and yields to 3/8". It rises with the sectional infeed roll on heavy cuts and is fully adjustable.

2. Quickly Adjustable pressure Bar

A heavy pressure bar is located directly behind the cutterhead. It is quickly adjustable by means of spring loaded micrometer-type adjusting screws at either end of the bar. If necessary, the pressure bar can be easily removed. Hard chrome plating is available as an option.

3. Sectional Upper Infeed Roll

All four 4" feed rolls are power driven. The upper infeed roll is the sectional type with 2" milled ductile sections. Each section yields 5/16" and the entire roll yields 3/4". All the other feed rolls are solid steel and easily removable. The feed rolls are mounted with sealed-for-life ball bearings. To adjust the machine from rough to smooth stock, a single hand lever quickly adjusts the table power feed rollers from .001 to .075.

4. Top View showing knife grinder with grinding wheel and stem in place. The grinding attachment can be left on the

machine during operation with either a gravity type or collection system-type dust hood in place.

5. As Standard Equipment each machine is equipped with a conveniently placed hand brake. As an optional feature, the machine can be ordered with a limit switch that shuts off power on both the cutter-head and feed motor when the hand brake is applied.

6. Positive Cutterhead Grinding indexing plate insures that each knife is ground in proper position.

7. The Northfield #7 Planer-Surfacer is shown here with a dust hood that can be attached to a central dust collection system. Model shown has the knife grinding attachment in place.
