When the 105*1.2*16 cutting disc is used, sometimes various problems occur, such as the surface of the cutting piece. If this happens, how to solve it?
Since the cause of burns on the cutting piece is high temperature, the main method of avoiding burns is naturally to reduce the generation of heat and accelerate the heat transfer. That is to say, reducing the action time of grinding heat and heat can avoid high temperature and burn on the surface of the workpiece. In production, the main methods to avoid surface burns on the workpiece of the cutting piece are:
1. Choose the right abrasive: the hardness of the abrasive itself is high and the brittleness is better. Such abrasives are not easily blunt during the grinding process, and the abrasive grains after blunt are easily broken to form a new sharp edge, thereby keeping the abrasive grains from cutting the workpiece, instead of rubbing against the workpiece to avoid grinding. A lot of heat is generated.
2. The use of resin bond cutting tablets is one of the effective measures to reduce burns. The resin binder burns off under the action of the temperature in the grinding zone, and it is not easy to burn the workpiece. For example, in the vertical flat grinding, a resin bond grinding wheel is often used for high-gloss grinding, and a fine-grained grinding wheel of a resin binder and graphite is used.
