What is used for grinding wheel hole making？Bubble alumina?
Bubble alumina can be used for grinding wheel hole making for the following reasons:
Lightweight and high strength: Alumina hollow balls have low density but high strength, which can reduce the weight of the grinding wheel and maintain structural stability.
High temperature resistance: Bubble alumina are resistant to high temperatures and are suitable for high temperature environments generated by grinding wheels when they rotate at high speeds.
Good thermal conductivity: Helps dissipate heat and prevents grinding wheels from overheating.
Chemical stability: Alumina has stable chemical properties, is corrosion-resistant, and extends the life of grinding wheels.
Application method
Mixed materials: Mix alumina hollow balls with binders and abrasives.
Molding: Molding by pressing or injection molding.
Sintering: High temperature sintering to solidify the binder and form a stable structure.
Precautions
Particle size selection: Select the appropriate particle size according to the pore size.
Binder matching: Ensure that the binder is compatible with the alumina hollow balls.
Process control: Strictly control the molding and sintering processes to ensure the performance of the grinding wheel.
In short, alumina hollow balls are suitable for grinding wheel hole making, which can improve the performance and service life of grinding wheels.
