Resin abrasive binders can improve the elasticity of abrasives to make them more suitable for precision machining in the following ways:1. Elasticity of resin abrasive binder itselfResin abrasive binders, such as phenolic resin abrasive and epoxy resin abrasive, have a certain elasticity. This elasticity can play a buffering role in the grinding process, reduce the impact of grinding force on the workpiece surface, and thus improve the finish of the machined surface. Especially for precision machining, tiny elastic deformation can make the abrasive grains fit the workpiece surface better and achieve a finer grinding effect.2. Improve the interface bonding between abrasive and binderResin abrasive binder can be evenly distributed on the surface of abrasive grains, firmly holding the abrasive grains in the abrasive tool. By improving the interface bonding between abrasive and binder, the shedding and breakage of abrasive grains during grinding can be reduced, and the durability and grinding efficiency of the abrasive tool can be improved. At the same time, good interface bonding also helps to transmit grinding force, so that the abrasive particles can produce appropriate elastic deformation during the grinding process and adapt to the slight undulations on the workpiece surface.3. Add elastic fillersAdding an appropriate amount of elastic fillers, such as rubber particles, elastic fibers, etc., to the resin abrasive binder can further improve the elasticity of the abrasive. These elastic fillers can absorb part of the grinding force during the grinding process, reduce grinding heat and grinding vibration, and thus protect the workpiece surface from damage. At the same time, the addition of elastic fillers can also improve the toughness and impact resistance of the abrasive, making it more suitable for precision machining of complex shapes and special materials.4. Optimizing the formula and process of resin abrasive bindersBy optimizing the formula and process of resin abrasive binders, its elasticity and grinding performance can be further improved. For example, adjusting the type and amount of resin abrasive, selecting appropriate hardeners and additives, and controlling hot pressing and curing processes can all have a positive impact on the elasticity of the abrasive. In addition, the use of advanced preparation technology and equipment, such as vacuum hot pressing and isostatic pressing, can also improve the density and uniformity of the abrasive, thereby enhancing its elasticity.5. ExampleTake phenolic resin abrasive binder as an example. By modifying it, such as adding polyethylene siloxane derivatives, its strength and toughness can be significantly improved. The modified phenolic resin abrasive binder can better transmit the grinding force during the grinding process, so that the abrasive particles produce appropriate elastic deformation, thereby improving the finish and precision of the machined surface. In addition, the modified phenolic resin abrasive binder also has good heat resistance and wear resistance, which can meet the precision machining requirements under harsh conditions such as high temperature and high speed.The resin abrasive binder can significantly improve the elasticity of the abrasive through its own elasticity, improving the interface bonding between the abrasive and the binder, adding elastic fillers, optimizing the formula and process, etc., making it more suitable for precision machining.
