How to make the abrasive tools that have been made soft down? The ceramic bond abrasive is immersed in a sodium hydroxide or potassium hydroxide solution, heated to the boiling point, and the concentration of the alkali solution and the boiling time are controlled to appropriately reduce the hardness of the abrasive. Refer to Table 1 for the compatible concentration boiling time. Table 1 Alkali treatment to reduce the hardness of the abrasive reference table Abrasive Grit Boiling time ( h ) Original hardness of abrasive tool K L M N P Q R S T Y Alkaline concentration ( % ) 10 20 30 10 20 30 10 20 30 40 24# 124 123 234 234 113 123 223 123 234 345 235 46# 124 234 345 356 134 234 245 112 123 234 123 60# 124 123 234 346 123 234 235 112 123 233 133 The strength of the grinding wheel after the treatment will be reduced. Therefore, it must...
