AI Technical Summary
In existing double-sided sharpeners, the gap between the groove bottoms tends to increase, causing thinner tools to fail to effectively contact the sharpening surface after entering, resulting in poor sharpening performance.
Design an interleaved grinding structure, wherein the first and second grinding surfaces are inclined outwards, and the bottom of the formed tool groove is close to 0. The first and second grinding surfaces tend to be laterally opposite each other, with an included angle of 30°-50°, to ensure that the cutting edge penetrates deep into the bottom of the groove and makes uniform contact. Tungsten steel inserts are used to enhance durability.
It achieves efficient grinding of thinner tools, resulting in better grinding effect, more uniform contact area, and extended service life of the grinding surface.
