Process analysis of expert and non-expert engineers in quartz glass bending process

Abstract

Quartz glass has a very high purity of silicon, and has heat resistance, chemical resistance, and excellent optical transparency. Therefore, it has been called the king of the glass. Quartz glass has a superior performance than other glasses. Especially it has been used as a key component of high-performance analytical instruments and scientific instruments and special manufacturing equipment. Because of its high heat resistance, it is difficult to the processing in a variety of shapes. General borosilicate glass can be mass produced by a hot press processing with precision mold. Quartz glass is difficult to mass-produced by mold because of its high melting point. Therefore, many of the quartz glass product is manufactured by engineer’s hand processing for each product. Therefore, in order to produce high-precision quartz glass product efficiently, engineers training is the most important. Also, engineers with a high processing technology has been aging in recent years. There are situations in which the tradition of technology is not going well. To keep stable supply of high-precision products, to analyze the processing technology of highly skilled engineers, it requires efforts to help education and training.
