7Column： Difference between vertical grinding and horizontal grinding

The vertical sawing saw (tooth mold) is as shown in the figure on the left, and the wood fiber is cut off at the tip of the teeth. The jagged groove plays a role in transporting sawdust. The angle of the back blade and the upper blade (cut blade angle) and the angle of the tip line and the back blade (cut angle) vary depending on the hard softness of the material to be cut. In the case of soft materials, both the cutting blade and cutting angle are sharp angles, and in the case of hard materials, the dull angles are made. The surface of the front and back blades is generally finished at right angles to the saw blades. Each tooth has its tip sorted to the left and right (clams / tooth vibrations), and is designed to prevent it from being caught in the material.

As shown in the figure on the left, the front of the upper and back blades is sharply cut (Nageshi), and the wooden fibers are cut like a sword. Each tooth is arranged alternately facing left and right. Also, add clams like vertical saws. There are several types of saws. In contrast to the simple structure of Ibarame, Edo-me has the tip of a file further grated with a file as shown in the figure.
