With large quantities of stepper motor control of the bearing grinding machine to the market, step motor system control problems are more and more surfaced, problems of single axis stepper motor control system is less, but more than two axis stepper motor system, often appear, such as the two systems are not synchronized, dimensions such as poor dispersion unstable failure.
    Stepping motor system there are many problems. We worked in the ball bearing inner ring groove grinding machine analysis and study, I tried the domestic several brands of stepper motor, found that the two systems are not synchronized phenomenon is serious. Sync error test from PLC, a control module, stepper motor drive and stepper motor.
    Oily SKF bearing as a foundation for mechanical and electrical parts have been widely used in automobiles, transaction machinery, household appliances products, electric tools, audio equipment, computer related equipment and other industries. Different working conditions of oil bearing proposed all sorts of different material and performance requirements, for example, general electric tools with oil bearing has special requirements to the wear resistance, sound mechanical with oil bearing requires a lower friction coefficient and so on.
    Due to motor SKF bearing chassis paint dry after oil, the chemical composition of volatile out corrosion of end face and outside groove bearings and channel, the channel is corrosion occurred after the abnormal sound. Corroded after bearing surface rust than the first one side is more serious. Caused by the purity of the bearing or grease, the abnormal sound of an irregular. I have no my voice, when big small without rules, are on high speed motor.
