Ceramic grinding wheels are commonly used for grinding bearings, mechanical arms, shock absorbers, cast iron, stainless steel, metals, ceramics, cast steel, knives, welds and other products. They are suitable for factories, stores, and home markets. They are easy to operate and have a wide range of uses.
Tips on ceramic grinding wheel:
The hardness of grinding wheel and the hardness of abrasive are two different concepts. The same abrasive can be made into grinding wheels with different hardness, which mainly depends on the performance and quantity of the bond and the manufacturing process of the grinding wheel. The significant difference between grinding and cutting is that the grinding wheel has “self sharpness”. Choosing the hardness of the grinding wheel is actually choosing the self sharpness of the grinding wheel. It is hoped that the sharp abrasive particles will not fall off too soon, nor will they fall off after being blunt.
The general principle for selecting the hardness of the grinding wheel is: when machining soft metals, in order to prevent the abrasive from falling off prematurely, the hard grinding wheel is selected. When machining hard metal, soft grinding wheel is selected to timely make blunt abrasive particles fall off, so as to expose new abrasive particles with sharp edges and corners (i.e. self sharpening).
The former is because when grinding soft materials, the working abrasive grains of the grinding wheel wear very slowly and do not need to be separated too early; The latter is because when grinding hard materials, the working abrasive grains of the grinding wheel wear faster and need to be updated faster. During fine grinding, a slightly hard grinding wheel shall be selected to ensure the grinding accuracy and roughness. When the thermal conductivity of the workpiece material is poor and it is easy to cause burns and cracks (such as grinding hard alloy, etc.), the selected grinding wheel should be soft.
