A sharpening stone used in an intermediate process in the blade grinding process. The frequency of use is high for use in the most important steps in the grinding operation.
It is used to remove fine scratches on the cutting edge at the roughing stage and to adjust the cutting edge. This process is 60-70% important in the grinding operation.
Abrasive work is greatly influenced by the gender, physical size, physical strength, etc. of the abraser. Therefore, it is desirable to examine the hardness and shape of the sharpening stone sufficiently.
This product is manufactured by high-pressure molding and high-temperature firing of a raw material containing high-temperature melt (about 1,200 ° C or more) type ceramic binder based on high-purity alumina grinding material. The strength of the glass is connected, and the synergistic effect with the fine pores present there is the best abrasiveness with the cutting edge of the new abrasive material always floating on the abrasive surface.
It excels in weather resistance, acid resistance and alkali resistance as an effect on the manufacturing method, and maintains its performance without deterioration in semipermanence without special attention in storage method as compared with the sharpening stones of other manufacturing methods.
