长春汽车厂底盘厂在端面外圆磨床上采用斜切入加工CA-15后桥车轴齿轮档的端面和外圆。在采用普通砂轮时,每修整一次砂轮后平均只能加工8～10件,端面就开始出现烧伤。影响了砂轮的利用率。如果将砂轮的硬度降低,则又将影响外圆的加工质量。为克服这一矛盾,该厂与第一砂轮厂(沈阳苏家屯砂轮厂)共同研制出一种双面砂轮,即砂轮加工外圆一侧 Changchun Automobile Factory chassis factory in the face cylindrical grinding machine used to bevel into the CA-15 rear axle axle gear gear end and the outer circle. In the use of ordinary wheel, grinding wheel after each trim an average of only 8 to 10 pieces, the face began to burn. Affect the utilization of the wheel. If you reduce the hardness of the wheel, it will in turn affect the processing quality of the outer circle. To overcome this contradiction, the plant and the first grinding plant (Shenyang Sujiatun Grinding Wheel Factory) jointly developed a double-sided grinding wheel, grinding wheel that is the outer side
