1. Improve grinding efficiency
In order to improve the grinding efficiency of the vitrified bond grinding wheels, the following aspects can be considered when adjusting the grinding tool formula. Choose abrasives with high hardness and high brittleness. The abrasive particle size can be slightly coarser, and the bond strength should be high and have a certain degree of brittleness. Reduce the hardness of the grinding tool appropriately to improve its self sharpening and increase the porosity.
2. Increase durability
The durability of vitrified bond grinding wheels is an important indicator for measuring their grinding performance. To improve the durability of the grinding tool, when adjusting the formula, good toughness abrasives and binders can be used. The hardness of the grinding tool can be appropriately lower during precision grinding, and higher during rough grinding.
3. Reduce the surface roughness of the workpiece
Abrasives should have good toughness, with appropriate selection of finer particles. The density of the abrasive structure should be uniform, and the hardness should be appropriately lower.
4. Improve machining accuracy
The selected abrasive has good toughness and is easy to maintain the shape of the working part of the vitrified bond grinding wheels. The abrasive particle size is appropriately fine, and the binder has appropriate toughness and a certain degree of shape retention.
5. Reduce burn deformation
Choose abrasives with high hardness and good brittleness, and the particle size can be appropriately coarse. The binder reduces toughness and increases brittleness to improve self sharpening. Reduce the hardness of the grinding tool appropriately, improve its self sharpening, and make it often have sharp cutting edges. For the organization of grinding tools, the porosity can be increased.
6. Avoid or reduce debris blockage
It is better for abrasives to have high brittleness and coarse particle size. Good brittle binders can be selected. Properly reduce the hardness of the vitrified bond grinding wheels, increase the porosity, and improve the chip capacity and chip removal ability.
It should be noted that the above adjustment measures for grinding performance are all considered from a certain perspective, and should be comprehensively considered in practical applications, and adjusted according to the actual situation. Only by starting from practical applications, through a series of repeated processes such as formula adjustment, experimentation, and readjustment, can the grinding effect of vitrified bond grinding wheels be optimized to the greatest extent.
