[0002] A knife grinder is a device that is mainly used to sharpen cutting tools used in the processing industry. Since the wear of the cutting tools is inevitable during the cutting process, grinding the tool blanks or re-grinding the already sharpened tools by a knife grinder can effectively reduce processing costs and improve product benefits. Among the existing knife grinders, CNC knife grinders have become the first choice for sharpening high-precision processing tools because of their high efficiency, high precision, and high quality when grinding tools.

[0003] When the existing CNC tool grinder is grinding tools, different tools have different requirements for the type of grinding wheel. Some tools require a coarser grinding wheel, while others require a finer grinding wheel. The demand for the type of grinding wheel requires frequent replacement of the grinding wheel. Manual replacement will take a lot of time and lengthen the entire production process. Moreover, when the grinding wheel is replaced manually, the entire CNC tool grinder will be splashed with cutting fluid, which not only increases the difficulty of replacing the grinding wheel, but also pollutes the environment around the tool grinder. Therefore, it is necessary to design a tool grinder that is easy to replace the grinding wheel to solve the above problems. Utility Model Content
