Precision machining development

Ultra-precision machining technology was gradually formed in the early 1960s with the continuous development of aviation, aerospace and computer, especially military engineering. Modern industrial products require extremely high precision parts, some of which have reached micro or sub-micron levels and can only be achieved by ultra-precision machining techniques. Ultra-precision machining is an important branch of ultra-precision machining technology. It combines a large number of new technologies on the basis of traditional machining, and is an important technology that has developed rapidly in recent years.
One: processing lathe
The UK first developed the world's largest ultra-precision machining lathe. 2. The United States has developed one of the most accurate lathes. The main shaft of the lathe uses high-pressure hydrostatic bearings.
Two: processing conditions
Good processing conditions are the guarantee of precision cutting, which is generally controlled and achieved by the temperature, vibration and cleanliness of the processing environment.
Three: cutting tool
For ultra-precision cutting, natural diamond single crystal turning tools are the most ideal tools. Research on the manufacturing process of diamond tools is also the focus of developing ultra-precision machining technology. In order to achieve extremely thin cutting, the tool must be sharp.
Summary: The above three points are the three main conditions for achieving ultra-precision machining, namely ultra-high precision machine tools, ultra-stable machining conditions and ultra-precision tools.
