Abstract

This utility model provides a wear-resistant and high-toughness composite titanium-based cermet cutting tool, relating to the field of metal cutting technology. It includes a tool head assembly, which comprises a titanium-based cermet base, a transition layer, and a composite wear-resistant coating. The composite wear-resistant coating is deposited on the surface of the tool head assembly by magnetron sputtering. The transition layer covers the outer side of the composite wear-resistant coating. The tool head assembly consists of a titanium-based cermet base, a transition layer, and a composite wear-resistant coating. The 8-12μm thick composite wear-resistant coating is applied to the surface by magnetron sputtering, effectively resisting wear and significantly extending the tool head's service life. The transition layer covers the outer side, enhancing the bonding force between the coating and the base, uniformly dispersing stress, and improving overall stability. The cutting edge on the outer side of the titanium-based cermet base has a reasonable angle design for efficient cutting. A locking groove below the base forms a tool clamping rod, providing a secure connection and facilitating installation and disassembly. This allows the tool head assembly to operate accurately and efficiently in various cutting operations, reducing maintenance costs and improving processing efficiency and product quality.
