How many ways are there to grind white corundum?

White corundum grinding methods can generally be divided into three categories: wet grinding, dry grinding and semi-dry grinding.

1. Wet grinding: also known as sand grinding, the liquid abrasive is continuously added or smeared on the grinding surface, and the abrasive continuously slides and rolls between the workpiece and the research tool to form a cutting motion.
, the particle size of the micropowder abrasive used is greater than W7.

2. Dry grinding: Also known as embedded sand grinding, the abrasive is evenly embedded on the surface of the research tool. When grinding white corundum, only a small amount of stearic acid mixed grease and other auxiliary materials are needed on the surface of the grinding tool. Dry grinding is often used for fine grinding, and the particle size of the micropowder abrasive used is as small as W7.

3. Semi-dry grinding: Similar to wet grinding, the abrasive used is a paste grinding paste. Grinding can be done by hand or on a grinder. Before grinding, the workpiece must use other processing methods to obtain higher pre-processing accuracy, and the grinding allowance is generally 5~30 microns.

Grinding tools are tools for grinding and forming workpieces. They are also carriers of abrasives. The hardness should be lower than the hardness of the workpiece and have certain wear resistance. Gray cast iron is commonly used.

The dry grinding tool is based on uniform and fine pearlite. Small workpieces with threads below M5 and complex shapes are commonly used in mild steel research tools.
Brass multi-purpose ﹑ copper research tools. The research tool should have sufficient rigidity, and its working surface should have high geometric accuracy.
The grinding tool is also cut and worn during the grinding process. If it is handled properly, its accuracy can also be improved, so that the machining accuracy of the workpiece is higher than the original accuracy of the grinding tool.
