＊Adding the cobalt into the white alumina enhances the toughness and creates the perfect balance between the plane retention of the grind surface and the separated grind grain.
This is the most recommendable product from the beginners to the professionals because of the smooth honing with the solid toughness.
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 grinding wheel sufficiently.
This product is manufactured by high-pressure molding and high-temperature firing of a raw material containing high-temperature molten (about 1,200 ° C or more) type ceramic binder added with cobalt oxide based on high-purity alumina grinding material. The glass of appropriate strength is connected between the particles, and the synergy effect with the fine pores present there is always the best abrasive taste with a new abrasive cutting edge in a state of being floated to 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 stone of other manufacturing methods.
