Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a cutting tool with an anti-wear coating. Background Art

[0002] As a key tool, the performance of cutting tools directly affects machining efficiency, workpiece quality, and production costs. In order to improve the durability and flexibility of cutting tools, the cutting part of the cutting tool is usually designed to be separated from the clamping handle to achieve rapid replacement of the cutting part, thereby avoiding damage to the cutting part that would cause the entire tool to be scrapped, and effectively extending the overall service life of the tool. At present, the cutting part of the cutting tool and the clamping handle are usually connected by ordinary thread connection methods. This connection method has the advantages of simple structure and easy operation, allowing the cutting part to be repeatedly installed and removed from the clamping handle, thereby achieving rapid replacement of the cutting part;

[0003] However, as the number of uses increases, the threaded connection parts gradually wear out, and thread slippage is prone to occur after multiple disassembly. Thread slippage not only leads to poor stability of the connection parts, affecting cutting accuracy and cutting efficiency, but may also cause the cutting part to fall off during the processing process, causing safety accidents. Therefore, we proposed an anti-wear coating cutting tool to solve the above problems. Utility Model Content
