Anti-sticking tool and preparation method thereof

Abstract

The invention belongs to the technical field of cutting machining tool manufacturing, and relates to an anti-sticking tool and a preparation method thereof. The anti-sticking tool material is a hard alloy or a ceramic material, the rake face of the tool is provided with a regularly-arrayed micro-bulge array structure, and sticking of a workpiece material can be effectively prevented during cutting; and the preparation method of the tool comprises the following steps that a 3D printing method is adopted to form a tool blank with the surface micro-bulge array structure on the rake surface, and then the tool blank is sintered at a high temperature to form the tool. The anti-sticking tool can be widely applied to cutting machining of easy-to-stick metal materials, and under the auxiliary cutting condition of a cooling liquid, the micro-bulge array structure contributes to the infiltration of a cooling medium, the cutting working condition can be remarkably improved, the cutting machining efficiency is improved, and the service life of the tool is prolonged.

Description

technical field [0001] The invention relates to an anti-adhesion tool and a preparation method thereof, belonging to the technical field of cutting tool manufacturing. Background technique [0002] During the cutting process, the rake face and the flank face of the tool are constantly in contact with the chip and the workpiece and have strong friction, resulting in tool wear. In some cases, the workpiece material is also prone to sticking, which hinders the cutting performance of the tool. At present, the main method to reduce the friction and wear of cutting tools and prevent the adhesion of workpiece materials at home and abroad is to use cutting fluid. However, as the amount of cutting fluid increases, its negative impact is also increasing. The use of a large amount of cutting fluid increases the manufacturing cost of the product, pollutes the environment, and damages the health of workers; on the other hand, during the cutting process, the cutting fluid really There a...

Problems solved by technology

At present, the micro-textures shown in reports are mostly micro-concave structure arrays. The textured tools of these micro-concave structure arrays have solved the problem of severe friction to a large extent. However, the micro-concave structures are easily blocked by chip materials.
