The design and craftability of copper casting machine tool castings. In addition to determining the geometry and size of the machine tool based on the working conditions and the design of the metal material, the rationality of the design, ie the size effect and solidification, shrinkage, stress, etc., should be considered from the characteristics of the casting alloy and the casting process to avoid Or reduce the composition of copper parts such as segregation, deformation, cracking and other defects. The second must have a reasonable casting process. According to the cast structure, weight and size, casting alloy characteristics and production conditions, choose the appropriate surface and shape, core method, reasonable setting of cast steel, cold iron, riser and casting system. Ensure access to high quality castings. Without the improvement of machine tool casting quality, the development of machine tool equipment manufacturing and the improvement of the overall level are not problematic, and ultimately affect the competitiveness of China's machine tool manufacturing industry in the international market. Continuously improve the quality of machine tool castings, thus ensuring the overall improvement of the machine tool manufacturing level. Design and technical advantages of machine tool castings for copper castings
Copper castings account for a large proportion of structural components. Many of the main components are cast for blanks, and are closely related to the quality and accuracy of the machine and the quality of machine tool castings. Machine quality, life, and accuracy remain important. Copper castings are also closely related to everyday life. For example, door handles, door locks, radiators, water pipes, pots, gas stoves, irons, etc. are often used. This is the largest application in ordinary sand casting, accounting for about 80% of all castings. Non-ferrous metal castings such as aluminum, magnesium and zinc are mostly die-casting parts. With the development of science and technology, the machine tool manufacturing industry is facing the frequency of manufacturing processing and processing, individualized processing objects, so that the machine tool industry provides processing and manufacturing equipment, and also requires product varieties, which has become an important indicator to measure the comprehensive strength of a country's machine tool industry.

The metal casting of copper casting can subdivide the crystal grains, reduce the pores, and improve the mechanical properties and air tightness of the alloy. In high-lead copper alloys such as lead bronze, metal casting is used to prevent the separation of copper components. Since copper alloy castings, cylindrical parts and the like are many, centrifugal casting is used more. In addition, large copper castings can also be used in low pressure casting methods to increase the density of the alloy and reduce the casting of inclusions in the casting. Some copper alloys can also be die casting methods. In the casting method, in addition to sand casting, non-ferrous alloys such as copper castings are widely used in special casting methods such as metal casting, centrifugal casting, low pressure casting and graphite casting.
