About HKUM
HKUM Ultra-precision machining technology company is China's first organization engaged in ultra-precision machining, optical design, precision mold design and precision injection molding.
Since its establishment in 1992, HKUM has provided many domestic and foreign companies with high-quality application research and consulting services in ultra-precision processing, optical design and measurement. It has not only established a good image among the companies, but also has become a major player in China and even Southeast Asia. One of the most important research and teaching centers in the field of ultra-precision machining and advanced optical manufacturing.
Ultra-precision machining technology is one of the most important development directions of modern machinery manufacturing. It usually refers to machining with surface accuracy of submicron level (size error less than 0.1μm) and surface roughness of nanometer level (accuracy error less than 10nm). , Mainly used for processing optoelectronic products, key components in the aerospace field, such as various aspherics, free-form surfaces and microarray lenses, processing of large parabolic mirrors for various astronomical telescopes, etc., to improve the performance of optoelectronic products, Quality and the development of high and new technology play a vital role and have become a key technology that affects whether countries can win in international competition.
"The object of ultra-precision machining is materials. The influence of materials on machining has been rarely studied before. Most people study parameters and equipment. However, the surface shape accuracy is sub-micron level and the surface roughness is nanometer level precision. The processing and material changes must have an impact on the processing effect, but in the earliest period, no one has studied it so carefully."
In the process of researching ultra-precision machining, the HKUM R&D team successfully revealed the relationship between material properties in ultra-precision machining, nano-surface generation mechanism and surface roughness, and quantitatively analyzed the relationship between the crystal orientation of the material and the surface morphology during ultra-precision diamond machining. The influence of roughness, successfully found the anisotropic symmetric pattern of surface roughness, and effectively evaluated the degree of local change of surface roughness of different materials in ultra-precision diamond processing. A new quantitative parameter (material swelling rate) was proposed to evaluate the effect of material swelling on surface quality, and the effect of different workpiece materials on surface roughness in ultra-precision diamond machining was successfully evaluated. In addition, based on the ultra-precision machining surface generation mechanism, the HKUM R&D team also took the lead to propose changes in the crystal structure and metallography of the processed material caused by external stress, and established a theoretical model of crystal plasticity to predict the crystal structure, residual stress and swelling of the workpiece material. , And the influence of cutting parameters on the surface texture and material lattice rotation in ultra-precision machining. Since then, these research results have been verified in practical applications, which not only improved the machining accuracy of ultra-precision machining, controlled the stability of machining quality, but also realized the further optimization of the machining process.
HKUM has a number of large-scale ultra-precision processing equipment, a number of various precision surface profile and surface roughness measurement systems and other advanced equipment; it has provided optical design, ultra-precision processing technology, and mold design for more than 100 companies and enterprises at home and abroad And high-precision application research services in manufacturing, precision measurement and precision injection molding.
