上海机床厂生产的MG1432A型高精度万能外圆磨床是1980年获得国家银质奖的产品。为提高产品质量和打开国际市场销路,1979年曾对本机床结构和外观作了一些改进,其中包括用振动小、噪声小的Z_2-02-MD型精密直流电机(0.55千瓦、2300转/分、电枢电压220伏、额定电流3.2安培)取代ZKJ-32型直流电机(0.45千瓦、1500转/分、电枢电压220伏、额定电流2.7安培)。因为更换了电机,电机结构参数改变,而调速装置仍用原来的
MG1432A high-precision universal cylindrical grinder manufactured by Shanghai Machine Tool Plant was a silver medal winner in 1980. In order to improve product quality and open the international market, some improvements have been made to the structure and appearance of the machine in 1979, including Z_2-02-MD precision DC motor with small vibration and low noise (0.55 kW, 2300 rpm, Armature voltage of 220 volts, rated current of 3.2 amps) to replace the ZKJ-32 DC motor (0.45 kilowatts, 1500 rev / min, armature voltage of 220 volts, rated current 2.7 amps). Because the replacement of the motor, the motor structure parameters change, and speed control device is still used the original
