1.Binder: Bismaleimide resin powder can be used as a binder or matrix material in the manufacture of diamond grinding wheels. In a grinding wheel, the abrasive grains are typically bonded to a base material to form the grinding surface. Bismaleimide resin has high thermal stability and mechanical strength to effectively bond abrasive particles to the grinding wheel substrate, ensuring durability and long-lasting performance.
2.Temperature resistance: Diamond grinding wheels are often used in high-temperature grinding applications where the workpiece material generates significant amounts of heat during the grinding process. The excellent thermal stability of bismaleimide resin allows it to withstand high temperatures without softening or degrading, ensuring that grinding wheels maintain their integrity and performance even under extreme conditions.
3.Dimensional Stability: Bismaleimide resin powder provide excellent dimensional stability, which is critical to maintaining the shape and profile of grinding wheels during high-speed grinding operations. This stability helps prevent wheel warping, deformation or loss of accuracy, ensuring consistent and precise grinding results.
4.Chemical Resistance: Diamond grinding wheels may be exposed to various chemicals, coolants or cutting fluids during the grinding process. The chemical resistance of bismaleimide resin ensures that the wheel is not affected by these substances, preventing the wheel from degrading or deteriorating over time.
5.Custom formulations: Manufacturers can develop custom formulations of diamond grinding wheels using bismaleimide resin to meet specific performance requirements. By adjusting the composition and properties of the resin matrix, they can tailor the wheel to optimize performance for specific grinding applications, such as high-speed precision grinding of hardened steel alloys or heavy-duty grinding.
