"This bearing is demanding. You look at the drawings. The design error here is only 0.02 mm. Pay special attention." At 8:30 in the morning, Ma Jianjun exchanged technical points with the apprentice. Ma Jianjun is a backbone member of the Machine Tool Performance Laboratory of Baoji Machine Tool Group Co., Ltd., Baoji High-tech Zone, Shaanxi Province. He has participated in the completion of key new product development trials and more than 30 major national special tasks, and has achieved more than 20 technological innovations. More than 50 trials, commissioning and after-sales services for special machine tools.
Ma Jianjun graduated from the Baoji Technical School. In July 1994, he came to the machine shop of Baoji Machine Tool Plant to become a general lathe operator. Only with the level of Chinese technology, he faced an unprecedented level of processing equipment and felt unprecedented pressure.
"I just want to learn the technology well, learn with the master during the day, and go home to study at night." Process, programming, electrical and cutting tools are the key to CNC machining technology. Ma Jianjun uses his good skills in turning technology, learning, In the middle school, if you encounter problems that you don’t understand, ask the master and the inspector, and check the information and take notes at night. In the past few years, he has recorded more than 10 study notes and applied it to well-known CNC systems. Ma Jianjun won the “Excellent Players†in the “Qinchuan Cup†Shaanxi Provincial First State-owned Enterprise Staff Skill Contest, and participated in the national, provincial and municipal vocational skills competitions for many times, serving as referee work or technical guidance. Since 2010, it has been awarded the “Troltech Technology Demonstration Post†by the group company. In 2015, it became the backbone member of Tian Haorong’s national master of skills (labor innovation).
In 2012, during Wuxi's four-month equipment technical service for a company, he overcame difficulties, fulfilled his duties with due diligence, and successfully completed the assignment. In recent years, the company has ordered more than 100 machine tools from the company.
In 2015, the key contract delivery of a Chongqing company was imminent. Due to tight time and high technical requirements, the company's leaders are very anxious. Ma Jianjun took the initiative to take this "hard bone". He has been nailed for more than ten hours in the user's trial production site. Overtime work has been carried out on each equipment for careful study and repeated honing. The process route map has been programmed, and the corresponding fixtures and corresponding tools have been prepared and finally completed. 14 CNC machine tools were scheduled for commissioning.
Since 2014, Ma Jianjun has participated in a number of national high-end CNC machine tool technology major special research and development trials. Especially during the work of national major special research projects and machine tool performance laboratories, he is skilled in machining BTGS12 spindles, tie rods and rollers of the ON-3VII, such as rollers and D-rings with high precision and small tolerance range. The business skills and processed parts exceeded the precision required by the drawings and the production tasks were successfully completed.
In addition, Ma Jianjun cooperated with the research team to overcome a number of technical difficulties and broke through a large number of key processing technologies for CNC machine tools. In the R&D and production of the BM63150C precision CNC lathe project, he boldly innovated and optimized the back-end oil return structure of the machine tool spindle, eliminating the weak links that affect the reliability of the machine tool; adjusting the cutting parameters and workpiece clamping methods through numerous explorations. Finally, the hard car process test was completed. The product won the “Spring Yan Award†from China Machine Tool Industry Association. He also successfully solved the technical problem of processing the clamping parts of the key new product BMC-500TV five-axis composite milling center. The company's first five-axis CNC machine tool entered the high-end market.
Ma Jianjun has more than 2 minor reforms and rationalization proposals for process improvement every year, and has completed more than 30 technical research projects with studio members. In 2016, his studio passed the acceptance of the National Master Skills Studio and won the “Full Total Staff Innovation Studio Research Fund†award. The advanced practices and experience were promoted and exchanged in Shaanxi Province, from ordinary operators to knowledge. Type workers, and then grow into a leap of expert talents in the new era.
