Third, the development of large aircraft must be based in the country, the development and application of domestic equipment
At present, most of the machine tools used by aircraft manufacturers are imported, and there are few domestically produced machine tools, and most of them are used for roughing. The main reason is: the precision maintenance, quality stability, and timeliness of service of domestic machine tools. There are still gaps in the requirements of aviation users, and some machine tools are still blank.
In order to change this situation, foreign machine tool manufacturers have some good practices in cooperation with aerospace manufacturing companies. For example, some foreign machine tool manufacturers have set up development departments for aerospace applications. The department's responsibility is to collect the needs of aerospace manufacturing companies, to convey these requirements to the product design department, and to research and develop processes and procedures for aerospace parts processing. Machine tool manufacturers also set up aviation customer sales managers, specializing in sales in the aerospace manufacturing market, strengthening ties with aerospace manufacturing companies, and responding to demand information in the aerospace manufacturing market. Domestic machine tool manufacturers can also learn from the advanced practices of foreign countries. First, they must understand the needs of aerospace manufacturing enterprises and the manufacturing processes of aircraft parts. Based on this, they should formulate machine tool design plans, study the appropriate process routes, and provide the ability to meet the requirements of aviation enterprises. machine tool. Most aerospace manufacturers have said that if domestic machine tools can meet the requirements, they are still willing to use domestic machine tools because the cost of domestic machine tools is low. In addition, the purchase of foreign high-end CNC machine tools, foreign set a lot of restrictions, not even sold to us.
Therefore, the development of large aircraft must be based in the country, the development of the above-mentioned urgently needed processing equipment, in order to be free from the constraints. China's machine tool industry enterprises should be brave and burdened, and worry about the country. Aero-engine manufacturers and aircraft manufacturers must also contribute to the revitalization of China's equipment manufacturing industry, actively use domestic equipment, help improve domestic equipment, and form an interactive innovation mechanism for production, education and research as soon as possible.

What materials can I choose for the cabinet handle? Which is good?
At present, plastic, zinc alloy, aluminum alloy, copper, stainless steel, gold and silver are commonly used in the market (these two kinds are basically useless unless the family really has no money to spend)
Plastic handle should be the cheapest. It's rare to know much about it, and it's not recommended to buy it. After all, it takes several years to install a handle, or it's more reliable to buy a metal handle. People of insight are welcome to add it in the comment area.
Zinc alloy is the most common material in handles. More than 80% of the handles you see in the market are made of this material. Why do you ask? Most of the handle manufacturers produce zinc alloy handles. The price of raw materials is medium, not as expensive as copper, which is easier to process. After electroplating, it is very beautiful and has enough weight, So consumers are willing to buy this high-quality and cheap product.
Aluminum alloy handle is popular in recent years. It is cheaper than zinc alloy and has low material density,.
Copper handle is the best material, which can be said to be the standard configuration of high-end handle. American, European, light luxury and other cabinets can be selected. It has a large density and heavy weight. It feels very textured, and its appearance and color are also very beautiful. In ancient times, the noble with status was equipped with a copper handle as standard. Of course, the price is also expensive. The raw materials are more than twice that of zinc alloy and aluminum alloy, so the finished products will only sell more expensive!
The style of stainless steel handle is relatively simple. Due to processing and market demand, there are few styles of stainless steel handle, and there is basically only one color, that is, wire drawing texture. We rarely buy it at home, and basically export it abroad.
The handle is bought according to the place of origin. The handle in Shanghai, Shenzhen and Foshan is better than that in Wenzhou. The electroplating process in Guangdong is really good. The price of the handle in these places is more than twice that in Wenzhou!
