1. Resin, debris and other debris adhering to the saw blade must be removed before grinding.
2. Grinding should be carried out strictly according to the original geometric design angle of the saw blade to avoid damage to the tool due to improper grinding. After grinding, it can only be put into use after passing the inspection to avoid personal injury.
3. If manual sharpening equipment is used, a precise limit device is required, and the tooth surface and tooth top of the saw blade are detected.
4. When grinding, special coolant should be used to lubricate and cool during sharpening, otherwise it will reduce the service life of the tool and even cause internal cracking of the alloy cutter head, resulting in dangerous use.
In short, the sharpening process of cemented carbide saw blades is different from that of ordinary circular saw blades. When the grinding rate is high, the grinding heat is high, which not only causes cracks in the cemented carbide, but also the sharpening quality is not good. Through reasonable grinding and use, the service life of the saw blade can be greatly extended (generally, the number of regrinds is about 30 times), which can better meet the requirements of processing technology, effectively reduce processing and manufacturing costs, and improve production efficiency.
