To grind this material, a porous grinding wheel must be used. Porous grinding wheels are now used to machine turbine parts. There are two reasons for this: First, for large material removal rate, the porous grinding wheel has better chip clearance; Second, the porous grinding wheel can provide more coolant to the grinding contact, thus reducing friction and ensuring lower grinding. Cut the temperature and reduce burns.
The porous grinding wheel consists of three parts: abrasive, pore-forming material and binder. In the past, the limit value of the grinding wheel hole can reach 60% of the total volume of the grinding wheel, while the bonding agent accounts for 15%~20%, and the abrasive only accounts for 20%~25%. Now, the binder has become a limiting factor in further improving the performance of the grinding wheel and reducing the risk of grinding burns. Although the bonding agent is indispensable for maintaining the overall shape of the grinding wheel, it also generates friction during cutting. Therefore, how to reduce the amount of binder as much as possible under the condition of ensuring the safe use of the grinding wheel is a major challenge for the grinding wheel manufacturer.
The new binder is a synthetic high-tech recrystallized glass that is highly reproducible and can be used up to less than 10% and subjected to greater loads. This not only reduces the amount of binder used to reduce the risk of grinding burns, but also reduces the cost of production by increasing the metal removal rate, while also reducing the cost of diamonds. 
Recrystallized glass acts as a porous wheel binder
Strict noise limits and fuel efficiency place higher demands on jet engine components. This means that a grinding wheel with higher performance is required.
