How to determine whether an alloy circular saw blade needs resharpening
First, when does a saw blade need to be resharpened?
Many times can be judged from a variety of scenarios, such as the cut-off iron chips, workpiece quality, saw blade benefits, etc.
1, sawing sound abnormal noise
In the sawing process, if the saw blade parts sound abnormal, rough cutting sound, or a "click, click" sound, should check the saw blade situation, in most cases, is a signal that needs to be resharpened.
2, cut off the quality of the workpiece
Saw blade in cutting off the workpiece, its quality is basically not too much difference, the surface is relatively smooth, no burr, if you find that suddenly the surface of the workpiece is not very smooth, or the same side of the thorns, iron chips sticky workpiece does not fall off and other phenomena, you can basically judge the saw blade resharpening time to come.
3、Sawing out of the iron chip color becomes heavy
When the saw blade cut off the workpiece, the chip color changes, such as color becomes heavier (more blue), etc., this time should check the state of the saw blade or check the equipment, and then look at the specific parameter changes, such as the number of cut off (square), according to the actual situation to determine whether the need to repair grinding.
Second, resharpening processing
Saw blade resharpening must be given to professional resharpening manufacturers for resharpening, not to deal with their own, or will use the saw blade completely damaged.
Three, attention
Saw blade to the need for resharpening, must be resharpened, not delayed or set aside to deal with.
Do not use the saw blade over time, the light will increase the difficulty of repair and sharpening, reduce the effect of the use of the repair, the heavy is directly scrapped.

The plate is thicker, each piece of micro-bending is not flat, the gap between the upper and lower stacked together; mechanical pressure cylinder pressure is not enough; workpiece plate surface stripes (bump) will also burst edge; work sawing less pressure 2-3 plates; sawing plate into the knife speed is properly adjusted to slow down the appropriate cut approved; check whether the saw blade is not sharp, timely repair the edge.
