When the aluminum build ratio is 1.2, the binder refractoriness is 845 ° C(brown aluminium oxide), and when the aluminum ratio is increased to 2.0, the refractoriness is 872 ° C. The pre-melting treatment can slightly reduce the refractoriness of the bonding agent, and is beneficial to the increase of the bending strength of the ceramic corundum abrasive tool(aluminum oxide 180 grit blast media). However, the effect of premelting treatment on different binders is different.

Among them, the effect on the bonding agent 4A is the greatest(brown fused aluminum oxide), and the bending strength of the abrasive strip can be increased by 10.lMPa at most after pre-melting. Among them, the flexural strength of the ceramic abrasive bar CA3H when fired at 820 ℃ is 51.4MPa. Filling holes is one of the hole diameter processing methods, with high production efficiency and easy hole diameter accuracy(black silicon carbide manufacturers). The amount of binder used in the abrasive formulation should be appropriate.


When the binder content is less than 22%, increasing the amount of binder can significantly improve the bending strength of the abrasive strip(white aluminium oxide). When the content of the bonding agent is greater than or equal to 22%, increasing the amount of the bonding agent has no obvious effect on improving the bending strength of the abrasive strip(silicon carbide companies). The flexural strength of the abrasive strip after pre-melting increases by only 2.3MPa.


Has the least effect on the bonding agent 5A(black aluminum oxide). In addition, when the tissue number of the abrasive is 8, and the mass fraction of the bonding agent is 22%, the amount of bonding agent is more appropriate. Within the test range, the increase in firing temperature can significantly increase the bending strength of the ceramic corundum abrasive test strip(brown fused aluminum oxide manufacturers). When the winding temperature reaches 900 ℃, the bending strength of the abrasive bar can reach 60.0MPa.


It was found that the average particle size of the ceramic corundum abrasive before heat treatment is 109nm(brown fused alumina), and the microstructure is dense: after sintering at 900 ℃, the average particle size of the crystal is 158nm. Although some crystals have abnormal growth phenomena, the crystal size is still relatively Concentration, the structure is still dense(brown aluminum oxide 80 grit), so ceramic corundum abrasive sintering at 900 ℃ is feasible, and the precision requirement is high.


After grinding, the grinding tool blank needs to be finished(green carborundum), so that the geometry and dimensional accuracy of the grinding tool can meet the quality requirements of the finished product, and the surface hardness of the grinding tool should be consistent with the internal hardness, and reduce the cost of the user's dressing wheel(white aluminium oxide 180/220). The increase of firing temperature can promote the crystal growth in ceramic corundum abrasive.


The method of grinding the grinding wheel is to use diamond grinding to grind the grinding wheel surface(brown aluminum oxide), use the grinding wheel to grind the grinding wheel, use the grinding wheel to grind the grinding wheel aperture, the grinding tool to grind the outer diameter, use the diamond saw blade to grind the grinding wheel surface(brown aluminium oxide grit), improve the appearance quality of the grinding tool product, and use the drill to guide the abrasive grinding tool Aperture, etc.


The aperture of the grinding tool is an important matching surface between the grinding tool and the spindle of the grinding machine(pink aluminum oxide). When turning fine-grained grinding wheels with diamond turning tools, when processing fine-grained graphite grinding wheels, rubber grinding wheels and fine-grained resin grinding wheels(best alumium oxide for glass blasting), special grinding stones made of ceramics or resin binders are generally used for turning.
