13. Groove cutting procedures
Cut grooves with saw blade
Grooves in the workpiece can be cut as indicated in Fig. 48 by adjusting the 6 mm
depth adjustment bolt.
Cutting depth adjustment procedure:
(1) Turn the stopper holder on the direction shown in Fig. 49.
Lower the motor head, and turn the 6 mm depth adjustment bolt by hand. (Where
the head of the 6 mm depth adjustment bolt contacts the hinge.)
(2) Adjust to the desired cutting depth by setting the distance between the saw blade
and the surface of the turntable (see b in Fig. 48).
NOTE:
When cutting a single groove at either end of the workpiece, remove the
unneeded portion with a chisel.
14. Cutting easily-deformed materials, such as aluminum sash
Materials such as aluminum sash can easily deform when tightened too much in a vise
assembly. This will cause inefficient cutting and possible overload of the motor.
When cutting such materials, use a wood plate to protect the workpiece as shown in
Fig. 50-a. Set the wood plate near the cutting section.
When cutting aluminum materials, coat the saw blade with cutting oil (non-combustible)
to achieve smooth cutting and a fine finish.
In addition, in case of a U-shaped workpiece, use the wood plate as shown in Fig. 50-b to
ensure stability in the lateral direction, and clamp it near the cutting section of the workpiece
and tighten it using both the vise assembly and the clamp available in the market.
