Grinding Site Conditions
A customer from South America has been purchasing 6A2 ceramic diamond grinding wheels from Moresuperhard company for grinding PCD cutting tools. Customers have always been satisfied with the grinding wheels provided by us, but when the order was placed on November 14, 2023, the blades jumped during use and the grinding wheels turned black. After the customer reported the problem, Moresuperhard quickly summoned experienced engineers to analyze the cause of the blackening of the grinding wheel during grinding.
Possible causes and solutions for grinding wheel blackening
The hardness of the grinding wheel is too high
A grinding wheel with too high hardness makes it difficult for the abrasive grains to fall off. You should choose a grinding wheel with moderate hardness to ensure that the abrasive grains can fall off quickly and keep the grinding wheel sharp.
Grinding wheel clogging
After grinding a large number of workpieces, the debris fails to fall off in time and adheres to the surface of the grinding wheel to form a blockage. The diamond grinding wheel needs to be polished regularly with a whetstone or dressing wheel to ensure that the surface of the grinding wheel is clean.
The temperature of the grinding wheel is too high
The heat continues to increase during the grinding process. It is necessary to increase the amount of coolant to reduce the temperature of the workpiece and the grinding wheel to ensure that the grinding wheel can work normally.
Excessive feed amount
The grinding wheel feed amount is large, resulting in an increase in cutting thickness and an increase in grinding temperature. The grinding wheel feed can be moderately reduced to reduce heat generation and prevent the grinding wheel from turning black.
