Description

Brush assembly for cutter passivation machine

Technical Field

The utility model relates to a sharpening technique technical field of cutting edge especially relates to a brush subassembly for cutter passivation machine.

Background

With the intensive research on the damage condition of the numerical control insert in the machining process, it is found that the microscopic state of the cutting edge of the insert and the roughness of the surface (especially the rake face) of the insert have great influence on the service life of the insert. This requires a better blade edge passivation process and a better blade polishing process.

The edge of the sharpened cutter generally has microscopic gaps (namely, micro tipping and saw cut) with different degrees. The microcosmic gap of the cutting edge is extremely easy to expand in the cutting process, and the abrasion and the damage of the cutter are accelerated. Modern high speed machining places higher demands on tool performance and stability, and generally after the tool edge is passivated before coating, the strength of the tool edge and the firmness of the coating can be improved, thereby prolonging the service life of the tool. Particularly, under the working conditions of processing steel parts and interrupted cutting, the cutting edge of the cutter is ensured to have certain strength, and then the cutting edge of the blade needs to be passivated.

The effect of the polishing of the insert surface on the useful life of the insert is evident, the lower the roughness of the insert surface, the lower the friction between the chip and the cutter body, the lower the cutting resistance, and the lower the heat generation of the insert, thereby extending the useful life of the insert.

However, after the existing cutter passivation machine passivates the cutter, a natural cooling mode is mostly adopted, and after the cutter is naturally cooled, the cutter is manually scrubbed; therefore, on one hand, the machining process of the cutter is reduced, and on the other hand, the labor cost is increased, so that the production and machining cost of the cutter is increased.
