Description

technical field

[0001] The invention relates to the technical field of TiC-based steel-bonded hard alloy precision machining, in particular to a TiC-based steel-bonded hard alloy fine-tooth external thread milling device and a numerically controlled milling method thereof. Background technique

[0002] TiC-based steel-bonded cemented carbide has the high toughness, high wear resistance and high compressive strength of cemented carbide. After softening treatment (annealing), it has the machinability, forgeability and weldability of steel, which makes up for the hardness of cemented carbide. It is difficult to deform and process, so it is widely used in the fields of cutting tools, abrasive tools and aerospace. However, the material also has its own defects. After strengthening treatment (quenching and tempering), the Brinell hardness (HRC) of the material reaches above 67, which is very hard and difficult to cut.

[0003] At present, the research on the conventional cutting ...
