Product parameters:

The angle of the finger joint knife mainly includes anterior angle, posterior angle and oblique angle. The angle of the finger joint knife is determined by the material of the processed wood, the depth of the finger joint, and the speed of the equipment. The depth of finger joints is deeper or shallower. The bevel angle is different when other conditions are the same. The rake angle and the rake angle are different for different speeds of the equipment. The slower speed requires a larger tool angle and the faster speed requires a smaller tool angle.

The tooth length of the finger joint knife is generally selected in the range of 4-60mm; the slope is usually about 1 / 11.4; in order to maximize the finger joint strength, the general tooth pitch should be 1 / 3-1 / 4 of the tooth length. The top width should be as small as possible, usually 0.2-2.5.
