Description
Technical Field
The utility model relates to a cutter blade passivation field, especially a frequency conversion supersound cutter blade passivation device.
Background
The cutting work of the cutter is mainly completed by the cutting edge of the cutter, but the cutting edge of the cutter has a plurality of defects, such as poor heat dissipation condition, lower strength and other structural characteristics. After the cutter is processed and produced or sharpened, some irregular defects or flanging still exist on the main cutting edge, so the durability of the cutter in the actual processing process is limited, and the service life is sharply reduced.
In cutting, it has been a major issue in metal cutting to improve cutting efficiency, to prolong the life of a tool, and to reduce production cost. The cutter cutting edge passivation technology has obvious effect on prolonging the service life of the cutter and receives more and more attention. The passivation of the cutting edge can remove the defects on the cutting edge of the cutter, increase the stability of the cutting edge, enable the front cutter face and the rear cutter face to share the mechanical load of the cutting edge part, reduce the abnormal failure of the cutter, and is an important method for solving the problem of early failure of the cutter.

However, the conventional uniform passivation cutting edge method is poor in global adaptability, and the cutting edge of the tool is seriously damaged due to large load, so that the bottleneck that the service life of the hard rotary milling tool is limited and the processing quality is improved is formed. The time-varying non-uniform loading characteristic of the cutter enables the overall suitability of the passivated cutting edge to be guaranteed to be the key for improving the performance of the cutter and prolonging the service life of the cutter, and a passivating device is urgently needed to conduct uniform or non-uniform passivation on cutters with different processing characteristics.
