A sharpening stone used for the final process in the blade grinding process.
Used for the most delicate steps in the grinding operation.
It is used to remove the fine scratches and “burly” that occur on the cutting edge during rough and medium grinding stages and to adjust the cutting edge.
In the abrading operation, this step greatly affects the sharpness of the blade and determines the longevity of the blade. 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 made of high-pressure raw material and high-temperature raw material that combines high-temperature melt (about 1,200 ° C or more) type ceramic binder based on high-purity alumina-based abrasive and zirconia-based abrasive used for precision polishing such as magnetic head. It is manufactured by firing, and the glass of the appropriate strength is connected between the particles of the sharpening stone, and by the synergetic effect with the fine pores existing there, always with the cutting edge of the new grinding material in the state of being floated on the abrasive surface Demonstrate the best abrasive taste.
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.
