Precision machining is a process of changing the size or performance of the workpiece with machining machine. According to the temperature state of the workpiece to be processed, it can be divided into cold processing and hot processing. Generally processing at room temperature, and does not cause chemical or physical phase changes of the workpiece, called cold processing. <br>
Generally, the processing above or below the normal temperature will cause the chemical or phase change of the workpiece, which is called hot processing. Cold working can be divided into cutting and pressure processing according to the difference of processing methods. Hot working includes heat treatment, forging, casting and welding. <br>

With the rising of economy and living standard, the number of cars is also rising. When we see so many cars, we can't help but realize the huge production behind the scenes of the manufacturers. Undoubtedly, China's mold industry has led the development of automobile industry. What impact does mold have on automobile manufacturing and what requirements does automobile manufacturing industry have on mold industry. <br>
The advantage of using mould is that it can reduce cost, save time and improve production efficiency, so that enterprises can be invincible in today's fierce competition. However, now the mold used in the production of cars, or plastic components, lights, steel shell and other accessories. The real car heart mobilizers still adopt cutting skills, but not mold skills. <br>
Unless the mobilizer can not adopt the mold technology, the crankshaft used in the automobile can not adopt this technology. Why? We all know that the components that adopt mold forming skills have a certain habit, which requires measurement and definite forming. For components with thickness and diameter like crankshaft and connecting rod, it is difficult to use die stamping. At present, the most acceptable method is to first use the die to make the rough die of crankshaft, and then use cutting to finish machining. <br>
When the machining accuracy request is very high, the mold often has more than enough force. The precision of today's very fine mold is roughly in the range of 0.1 ~ 0.01mm. Compared with the previous mold, the precision has been greatly improved. However, components such as mobilizers require an accuracy of less than one thousandth of a millimeter, or even less. Therefore, nowadays, it is not necessary to completely replace cutting with mould. <br>
The gloss and roughness of mould have been greatly improved. However, the mold itself is also made by the machine tool, if the accuracy of the machine tool making the mold itself can not pass the standard, the accuracy of the product will not be high. Therefore, mold experts feel that the adoption of excellent mold skills is the inevitable trend of fierce competition at present, and the need to improve the competitiveness of mold to get used to the market is the top priority. Actually raising the mold's high precision is not only the request of the mold industry's progress, but also the heart of the automobile industry and other industries.
