SHARPENING THE CUTTER BLADES

Use of the accessory Blade Sharpening Ass'y is
recommended for convenience.
(1) Use of Blade Sharpening Ass'y.
As shown in Fig. 16, two blades can be mounted on
the blade sharpening ass'y to ensure that the blade
tips are ground at equal angles. During grinding,
adjust the position of the cutter blades so that their
edges simultaneously contact the grinding stone as
shown in Fig. 17.

(2) Cutter blade sharpening intervals
Cutter blade sharpening intervals depend on the type
of wood being machined and the cutting depth.
However, sharpening should generally be effected
after each 1,640ft (500 m) of cutting operation.
(3) Grinding allowance of the cutter blades
As illustrated in Fig. 18, a grinding allowance of 0.14"
(3.5 mm) is provided for on the cutter blade. That is,
the cutter blade can be repeatedly sharpened until
its total height is reduced to 0.96" (24.5 mm).
Grinding allowance
(4) Grinding Stone
When a water grinding stone is available, use it after
dipping it sufficiently in water since such a grinding
stone may be worn during grinding procedures,
flatten the upper surface of the grinding stone as
frequently as possible.
