After a period of time, the saw blades of metal circular saws will produce blades that are not sharp. The circular saw blades need to be re-sharpened, which will help the service life of the saw blades. Under normal circumstances, the metal circular saw blades can be repaired. Grind two to three times, depending on actual usage. Metal circular sawing machine saw blades need to be sharpened. Many times, it can be judged from a variety of scenarios, such as cut iron filings, workpiece quality, and saw blade benefits.

　　The following editor introduces the circumstances under which circular saw blades need to be sharpened.

　　1. The color of the iron filings cut by the metal circular saw becomes heavier

　　After the metal circular saw blade cuts the workpiece, the color of the iron filings changes, such as the color becomes heavier (bluer), etc. At this time, you should check the status of the saw blade or check the equipment, and then look at the specific parameter changes, such as The number of cuts (square), according to the actual situation to judge whether it is necessary to grind.

　　2. Judging by the quality of the workpiece cut by the metal circular saw.

　　When the metal circular saw blade is cutting the workpiece, the cutting surface of the sharp blade is generally smooth and free of burrs. If it is found that the surface of the workpiece is suddenly not very smooth, or there are burrs on the same side, the iron filings will not fall off the workpiece, etc. Phenomenon, it can basically be judged that it is time for saw blade grinding.

　　3. The sound is abnormal when the saw blade of the metal circular saw is cut

　　During the sawing process, if there is an abnormal sound at the saw blade, when it is rough, or there is a "click, click" sound, the condition of the saw blade should be checked. In most cases, it is a signal that needs to be sharpened.
