Electric circular saw blade knowledge-2
Post Time: 2016-08-17
Edge inclination:
The main impact of the chip flow direction, increasing sharpness, but the blade angle over the General Assembly to reduce the strength of the tip, the blade, and therefore according to the foreign samples, select the range of saw blade angle 8-10 °.Main angle (tooth angle points):
Increasing the lead angle in favor of chip discharge, reduced friction, but too much will reduce the strength of the tool, resulting in reduced life expectancy. This angle is generally taken 10-12 °.The other two vice declination, mainly in favor of chip, reducing friction. This angle generally take 2-3 °. 3.Processing
The original process:Blanking molding ---- ----- take stress matrix hardening and tempering (plastic) ------ ----- mill hinge bore welding plane ----- ----- teeth grinding tooth sandblasting ----- ----- printing
Online process: blanking molding ---- ----- Stress relief annealing the substrate tempering (plastic) ------ ----- mill hinge bore welding flat tooth --- ----- - grinding teeth grinding ----- ------ ----- blasting printing.
After the original process grinding sandblasting, cutting edge and the blade sharp edge passivation, affecting the sharpness of the blade, increasing the sandblasting process after grinding, so keep the blade sharp, extended service life.
