This product requires a high level of processing accuracy. Comrade Zhao Junming, the company's annual advanced individual, has undertaken the processing tasks of the internal and external channels. In order not to affect the processing progress of the product, Zhao Junming, Zhang Zhiqiang, Yu Yongqiang and others in the large and medium-sized workshops of the rail transit branch took the initiative to work overtime to debug the machine tools. Finally, after unremitting efforts, the sparse wave, dense wave, groove curvature, roundness and roughness of the processed channel exceeded the requirements of the process drawing. After learning the result, all the participants showed a happy smile. Zhao Junming said excitedly: "This is a product with the highest processing level in the history of the branch, and it is also the most satisfying one since entering the factory!" Because it was the first time to process the insulating bearing of wind power motor, the user unit appointed an engineer to the factory to inspect the product. The whole process of fitting, cleaning, packaging and other processes has been tracked and tested. The user engineer finally expressed his satisfaction and allowed the trial-manufactured finished product to be installed and tested, and it is expected to enter mass production.

Wind power motor insulating bearings are high value-added products. The successful trial production has not only added a new bright spot for the company to open up the market, but will also become a new profit growth point for the company. It is a comprehensive affirmation of the technical capabilities of front-line workers in industry technology research and development and production.
