The new trend of precision parts processing equipment in upgrading intelligent manufacturing
In terms of domestic sales of precision parts processing, with the increasing demand in the domestic professional manufacturing field and the gradual improvement of the sales channel system, the situation that enterprises worried about small domestic sales and slow payment collection in the past has also been greatly improved. The enterprise can not only build its own domestic sales system, but also cooperate with trade
dealers with strong comprehensive strength to jointly develop the market. The stable domestic market will not only help enterprises to effectively resist overseas market risks, but also bring more business opportunities for the development of enterprises. At present, the overall situation of precision machining in China is that world-class machine tools are used for second or even third class products. Although the country has invested a lot of manpower, material resources and financial resources in some cutting-edge manufacturing fields, such as military industry, aerospace and aviation, most precision processing industries are still in the status quo of "using world-class machine tools to make second-class or even third class products".
With the increase of labor cost in the past two years, the price advantage of medium and low-grade CNC precision cutting machine tool exports will gradually lose, and the export volume will inevitably decrease. If machine tool enterprises continue to focus on the production of traditional standard cutting machine tools, the sales volume will gradually shrink and there will be no future for development. Ultra precision machining technology is the key bottleneck technology of advanced equipment manufacturing, and nano precision is known as the "pearl on the crown" of ultra precision machining technology. In the past, due to the backward processing technology of optical parts in China, it was impossible to process optical parts with large diameter, high precision and complex surface shape, which seriously restricted the technological progress in related fields. As early as the late 1980s, Japan took ultra precision machining technology and micro machining technology as national key development projects. By the middle of 1990s, it had entered into large-scale research and development. In 1993, it had developed a multi axis machining device with accuracy controlled at 1nm. With the combination of optics and IT technology and the development of photoelectric technology, the requirements for optical element processing are becoming higher and higher, which further promotes the development of precision machining technology.
