The level of technology and technological content of mold production has become the primary mark to weigh the level of science and technology and product production of a country. It determines the quality, efficiency and development strength of new products to a great extent, and determines the international competitiveness of a country's manufacturing industry. According to the development of domestic and international mold market, mold experts speculate that the precision of China's mold will be higher and higher after the adjustment of professional structure. Mold is the basic process equipment of industrial production. In electronics, automobiles, motors, electrical appliances, instruments, home appliances and communication products, 80% - 90% of the parts depend on mold forming. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determines the quality of these products. <br>
The first is the requirement for the hardness of materials. For some occasions, the higher the hardness of materials, the better. It is only limited to the hardness requirements of processing parts. The processed materials should not be too hard. If they are harder than the parts, they cannot be processed. <br>
Secondly, the material is moderate, at least one grade lower than the hardness of the parts. At the same time, it also depends on the function of the processed devices and the reasonable material selection of the parts. <br>
In short, there are still some requirements for materials in precision machining. Not all materials are suitable for machining. For example, if the materials are too soft or too hard, the former is unnecessary, while the latter is impossible. Therefore, the most basic one is to pay attention to the density of the material before processing. If the density is too large, it is equivalent to the hardness. If the hardness exceeds the hardness of the machine part (lathe tool), it is impossible to process. It will not only damage the parts, but also cause danger, such as the tool flying out to hurt people. Therefore, generally speaking, for mechanical processing, the material should be lower than the hardness of the machine tool, so that it can be processed. <br>
Steps of precision machining: < br > 1
1、 It is the main technical document to guide production
The production planning and scheduling of machining workshop, the operation of workers, the processing quality inspection of parts, and the accounting of processing cost are all based on the process specification. To deal with the problems in production, the process specification is often taken as the common basis. If dealing with quality accidents, the responsibilities of relevant units and personnel shall be determined according to the process procedures. <br>
2、 It is the main basis of production preparation
When the workshop wants to produce new parts, it is necessary to first formulate the machining process specification of the parts, and then make production preparation according to the process specification. For example: the analysis and research of the key processes in the processing technology of new parts; the preparation of the required knives, clamps and measuring tools; the purchase or manufacture of raw materials and blanks; the purchase of new equipment or the modification of old equipment, etc. must be carried out according to the process. <br>
3、 It is the basic technical document of new machinery manufacturing plant
When building a new batch or large batch machining workshop, it is necessary to determine the type and quantity of machine tools required and the layout of the workshop according to the process specification, and then determine the size of the workshop area, power and hoisting equipment configuration, as well as the type of work, technical level and quantity of workers required
