Post-treatment process of high-gloss formed cutter

Abstract

The invention discloses a post-treatment process of a high-gloss formed cutter. The post-treatment process comprises the following steps that a cutter hole is formed in the center of a clamp, the part, directly participating in polishing, of the clamp is arranged to be in a cutter profile shape according to distribution of cutter edges, it is ensured that the distances between all the positions ofthe cutter and the clamp are equal, and four evenly-distributed pressure relief holes are additionally formed in the clamp; an abrasive material for cutter fluid polishing is made of a macromoleculesemi-solid carrier and abrasive grains in a mixed configuration mode according to the ratio of 3:2; and the fluid polishing process is conducted through the steps that (1) a power switch of a polisheris turned on, the configured abrasive material for cutter fluid polishing is put into a lower cylinder of the polisher, the clamp is fixed to a worktable, and the to-be-passivated cutter is fixed tothe clamp; (2) the polishing time and the abrasive material pressure are set, a machine is started, pistons in an upper cylinder and the lower cylinder make reciprocating movement at a constant speed,thus the abrasive grains flow through the cutter and edge openings uniformly, and polishing passivation is completed; and (3) after being polished, the cutter is taken out, and replaced with a new to-be-polished cutter. Overall force bearing is uniform and constant, the passivation effect is ensured, and the passivation time is saved.

Description

technical field [0001] The invention belongs to the technical field of grinding tool passivation, and in particular relates to a post-treatment process for high-gloss forming tools. Background technique [0002] Tool passivation can prolong the service life of the tool, improve the processing efficiency and precision of the machine tool, and reduce the surface roughness of the workpiece to be processed. After the passivation treatment, the cutting edge of the tool becomes very smooth, which greatly reduces chipping and improves the surface finish of the workpiece. [0003] At present, the existing passivation process on the market is two kinds of passivation with walnut powder and manual polishing. The passivation of walnut parts is to submerge the tool into the walnut powder, and then through the revolution and rotation of the tool to make the uniform friction and collision between the cutting edge of the tool and the walnut powder to achieve the purpose of passivation, bu...

Problems solved by technology

The passivation of walnut parts is to submerge the tool into the walnut powder, and then through the revolution and rotation of the tool to make the uniform friction and collision between the cutting edge of the tool and the walnut powder to achieve the purpose of passivation, but the buried depth of the tool is different when the walnut powder is used for passivation. During the passivation process, the impact and extrusion of the cutting edge will be different, which will inevitably make the passivation of the tool unev
