What kind of grinding wheel is used to grind two materials (tungsten steel and high-speed steel) at the same time?
When grinding tungsten steel and high-speed steel at the same time, you need to choose a grinding wheel that can take into account the grinding needs of both.
1) If the high-speed steel is not quenched, you can choose a diamond grinding wheel and appropriately increase the diamond concentration to ensure the life of the grinding wheel.
2) If the high-speed steel has been quenched, you can consider adding some CBN to the diamond to ensure sharp cutting.

3) Considering that grinding tungsten steel and high-speed steel at the same time will generate a lot of heat, choose fillers with good thermal conductivity.
