Have you used pushing table saw for cutting material? Or during the pushing table saw using process, have you encountered the crack edge condition? If yes, do you know the reasons for such terrible condition?

If the crack edge condition is at the top, the possible reasons would include these reasons. Firstly, main saw blade is too blunt or the number of saw teeth is too much less. Secondly, main saw blade is not higher enough than cutting panel. Thirdly, cutting panel itself is with poor quality so that it will make saw blade become blunt.

Based on these three reasons, you can take such solutions, for example, change saw blade, or increase the height of main saw blade, or choose top quality panel for cutting, which include less impurities particle.

On the other hands, if such crack edge is at the bottom, here are three reasons, firstly, the assistant saw blade is too blunt, secondly, the width of assistant saw blade is not enough, in other words, it is too narrow, thirdly, the center line of main saw blade and assistant saw blade is not coincident.

OK, here are also three solutions for such problem, change new saw blade, or increase the thickness of saw blade, or change the location of assistant saw blade.
