Vacuum coating machines optical processing technology development

               

  The development of optical processing technology and the future trend of the vacuum coating machine, the cold working of optical coating parts in China is very rare in the Republic of China. In 1950s, it is almost duplicated from the introduction of optical processing technology by the Soviet Union and East German socialist countries. The optical cold processing uses the abrasive grain rough grinding, fine grinding, the classical type polishing. The processing efficiency is low, at the same time to the operator's technical requirements, each operator has to go through many years of technical post training to be officially posts. Technology better workers can be from the processing of rough to polishing, alone to complete the full line of work. At this time, the optical cold processing mainly depends on the skill and experience of the technical workers, and the process design is not very important in this period. At that time there is no strict process standards, usually only in the processing requirements of the process size, surface accuracy and appearance, etc., and processing parameters can not be clearly defined, by the operator in accordance with the individual's personal experience to adjust the processing, as long as the production of parts can be in accordance with the requirements of the drawings. Usually the labor of each enterprise is an excess, the production efficiency is much less than that of the political thought.
  With the introduction of the ball mill, the mill, the labor intensity of the operator is relieved, and the machining efficiency is greatly improved. Process requirements have been improved, but because of the low accuracy of the equipment, the demand for the post process is not changed, the role of the process standard is not obvious. Then in high speed polishing of quasi sphere centre, optical cold processing production efficiency increases rapidly, workers more clear division of labor, technology standard has improved significantly. In the production process is a decisive role in the production process, the main content of the work of the daily work of enterprises, the old workers' technology from the past, the role of the dominant role, becomes a supporting role. According to the standard operation, according to the standard operation, according to the standard production and other slogans, become the fundamental of every modern enterprise production. The process method, process route and technology standard, which is developed by the technical staff, play an important role in the production of enterprises.
