48 year old Zhang Liangfeng is the assembly fitter of Ji'nan two machine tool group NC machine tool company, high Technician is proficient in the assembly and debugging of the key components of the large scale five axis CNC machine tool and the complex double pendulum universal milling head. For more than 20 years, he has participated in the assembly and debugging of the first CNC machine tools, which have been undertaken by many countries, and has conquered many technical difficulties and became the technical master of the production line.
Zhang Liangfeng / > in the work of
in 1989, Zhang Liangfeng technical school after graduation to the Ji'nan two machine tool work, with the enterprise for skilled personnel to build a good platform and personal diligence, he soon stand out. Before and after 2004, Zhang Liangfeng began to participate in the assembly and debugging of large and high-grade five axis CNC machine tools, especially the key core functional components and the complex double pendulum universal milling head. This kind of CNC machine tool is a high speed, high efficiency and high precision machining equipment that is needed in the key industries of the national economy. Ji'nan two machine tool is the only enterprise in China that has independently developed the key core functional components, and has undertaken several major projects in many countries. In the face of such high-tech products, in the assembly and commissioning, Zhang Liangfeng often meets a variety of technical problems, such as the sealing ring, bearing, measuring parts of the installation process is complex, the process requirements are high, the parts are large and small, some are imported, it is easy to damage in the installation process, and the improper installation will also affect it. Technical performance.
Zhang Liangfeng knows that only by practicing solid technical skills can he cope with more and more complex problems. He worked hard and studied hard, with many years of experience in installation, with the technical personnel to overcome the difficulties, completed the double swing angle CNC universal milling head inside the sliding pillow pipeline layout improvement, the use of infrared thermograph to solve the problem of milling head temperature rise, double swing angle CNC universal milling head improvement and other technological innovations.
in 2015, when a user in Harbin carried out the equipment security, the signal line of the C axis grating inside the milling head appeared broken line, because it could not be disassembled inside the sleeper, and it was not easy to observe, only by reaching the narrow space touch to judge. If the milling head is completely dismantled, it will take two or three days and the user will not be satisfied. As a result, with the sense of hand and experience, he confirmed that it was the first use of an imported detachable plug, immediately in the field design and manufacture of the tooling, dismantling the plug, after the electrician repaired the plug back, only used more than two hours to exclude the failure, the user is not the best.
large power devices need more and more large country craftsmen. Zhang Liangfeng's group of young workers, in order to make them grow up as soon as possible, he often explained the characteristics of different product structure and attention, organized them to learn new technology, combined with practice, to improve the operation level of young workers. In the long line production, he used his attention and rigour, perseverance and diligence, annotated the spirit of the craftsman, became the only chief technician selected by the workers in the enterprise, won the honors of the national youth post, the outstanding contribution technicians in Ji'nan, and became a model for the new generation of mechanical craftsmen.
