Precautions and industrial requirements for detailed machining
2024-04-30
Meticulous machining is a kind of casting process with little or no cutting. It is a good process technology in the casting industry, and its application is widespread. The reasons for choosing meticulous machining are as follows:
It can use common materials and can utilize a large amount of scrap metal and recyclable resources. Compared with ordinary forging methods, it consumes less. The cost is OK, the comprehensive economic performance is good, the energy consumption is not high, and the consumables are few. The application range of casting is wide, and it is not limited by the size, thickness and shape complexity of the casting, and the production mode is convenient. Investment casting has high dimensional accuracy and surface finish, which can reduce the workload of machining. Superalloy castings can be cast, such as jet engine blades, streamlined profiles, and cooling chambers that are difficult to form by machining techniques. The casting has corresponding dimensional accuracy, small machining allowance, saving processing time and metal materials.
The industry requirements for meticulous machining are as follows:
1, the formation of some of the correct structure, the overall combination of production and education and training base, can continue to transport talents to the enterprise, continue to produce, new varieties of casting materials, to meet the growing demand for casting materials, while gradually increasing the intensity of technology import and export.
2. It is necessary to complete the adjustment of industrial structure, eliminate a number of small casting factories with low technical level, poor product quality, serious pollution and poor economic benefits, and form relatively concentrated "small giants" and "enterprises" to realize "chemical and large-scale" production.
3. Complete the transformation of the growth mode from labor and resource intensive to technology capital intensive, from extensive pollution type to green intensive type. The quality, variety and quantity of products are equivalent to the world level, and the proportion of materials increases. The production rate and economic benefits of the whole casting factory have doubled; environmental pollution control, China's casting material industry system coordinated with the environment has been initially established.

What are the factors that affect high product components?
Machining has been used in many applications, because the current mechanical manufacturing requirements for output has declined, the requirements for size and shape have gradually increased, and high-product parts have a new development trend. The use of lathes requires different turning methods, but grinding, cutting, milling and other processes can be carried out in one lathe, and the development trend of process integration is more obvious.
