Description

Technical Field

[0001] The utility model relates to the technical field of ceramic grinding wheels, in particular to a ceramic grinding wheel provided with a cooling channel. Background Art

[0002] A grinding wheel is a cutting tool that uses abrasives to cut. Most grinding wheels are made with a vitrified bond, which is a special clay mixture. In the kiln where the grinding wheel is made, the clay and abrasive grains melt into a molten glass state at high temperatures. During the cooling process, the ceramic forms a link that allows each abrasive grain to be closely adjacent and supports the abrasive grains during grinding. Grinding wheels made with vitrified bonds are very strong, tough and porous. They can quickly remove material chips and can be accurately ground to the required precision.

[0003] Ceramic grinding wheels generate a lot of heat when grinding metal workpieces, and coolant is needed to cool them down. However, the coolant is only aimed at the grinding position of the metal workpiece, and the heat dissipation effect at other positions is poor. In addition, a large amount of dust is generated during grinding, which mixes with the coolant and pollutes the coolant. The coolant needs to be collected and filtered before it can be recycled. For this reason, we propose a ceramic grinding wheel with a cooling channel. Utility Model Content
