State Engineer Center of Huagong Manufacture Equipment-Digitalization (Abbreviation: Engineer Center) is a authoritative state engineer company working on manufacturing digitalized equipments. Engineer Center take advantage of Huazhong University, and have established good relationship with Wuhan Heavy-duty Machine Tool Co., Ltd, Dalian Machine-bed Group Co., Ltd, Xi'an Dongfeng Electrical Machine Co., Ltd and Wuhan Huazhong Numerical Control Co., Ltd, which focus on research of production and industrialization, and developing high technical process and equipments at high level of contribution.

Engineer Center located in the modern technical country in Huazhong university of Science & Technology, have working area of R&D department, production factory and sales department for more than 17, 000 square meters, more than 240 employee including R&D engineers and managers: 132(professor: 22, associate professor: 37, Doctor: 56, senior engineer&senior manager: Up to 50%); Production engineer and sales person: 60; Training and business support person: 48. R&D base and producing base are established which have created a basic structure of technology development, pilot and production. Currently, Engineer Center has been working on research, development, production and sales of digitalized equipments for high requirement with complete after-sale service, production update system and quality control system in the following field: Machine-bed, car, steel industry, ship, microelectronics, military industry, light industry etc...

Product demand of high quality cold-rolled sheet metal and production technology have increased a lot with the mature metal market. How to make surface of sheet metal with low roughness, high peak value and disorder wear-resistant shape has become the most important technology which highly focus by numerous oversea and domestic enterprises.

Fiber laser texturing utilize pulse laser beam with high power and high frequency formed by expander, polarizer and focus lens make small concave on surface of sheet metal, at the same time, flowing gas with specific pressure, direction and rate of flow make melted material in the melting pool become boss and pit. As a result of fast heating up of laser, fast cooling down of roller, crystal grain refined and crystal lattice dislocated while boss and pin in the stage of solidification and phase hardened in 10-5 sec, finally, the hardness of surface can be up to HV1000. Steel quantity over can be increased a lot, roller consumption can be decreased and production can be more stable by fiber laser texturing. The whole process of surface texturing: Performed less than 20um under surface of roller, no effect on roller figure and secondary grinding, no medium, and without noise and pollution.
