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.
