A tic-based steel-bonded cemented carbide fine-tooth external thread milling device

Abstract

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, which includes a box with an opening on the upper end, and the box is filled with cooling liquid. A fixing seat is installed in the bottom surface of the box body, and a spring chuck is installed on the upper end of the fixing seat. The spring chuck is used to fix the parts to be milled. When the parts are fixed, the height of the upper end of the parts is lower than that of the box body. The height of the side wall, a milling cutter is hung on the side of the part, the milling cutter is coated with polycrystalline diamond, the main cutting edge of the milling cutter is in the form of two edges, and the two edges are coplanar.

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. 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 high toughness 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 process of TiC-based steel-bonded carbide mate...
