[0002] Cubic boron nitride blades are artificially synthesized using cubic boron nitride powder and a small amount of binder under high temperature and high pressure conditions. Their hardness is second only to diamond and far higher than other materials. They are called superhard tools and are often used for cutting ferrous metals.

[0003] Some existing cubic boron nitride tools for grooving are usually fixedly installed on machine tools, and the blade is fixedly installed with a locking bolt when installed on the tool handle. In actual use, when processing grooves of different shapes on the same workpiece, the blade needs to be replaced, and the sizes of different blades may vary to a certain extent. Therefore, secondary positioning may be required after replacing the blade. However, some existing tools are not convenient for fine-tuning the position of the blade after installation. Therefore, it is necessary to adjust the position of the entire tool and the machine tool to ensure that the tool and the workpiece position correspond. The adjustment method is relatively cumbersome and the efficiency of fine-tuning is low. If the position of the blade is not actually adjusted, errors are likely to occur in the subsequent processing of the workpiece, reducing the processing accuracy and efficiency. In view of this, we propose a cubic boron nitride tool for grooving to solve the above problems. Utility Model Content
