| China's wire-cutting machine tools originated in the early 1970s. Before the implementation of the market economy, the development of wire-cutting machine tools was relatively slow, mainly because China’s electronics industry was relatively backward, and the production lines of wire-cutting machine tools were all state-owned enterprises. Strong ability, but due to the disconnection from the market, combined with the constraints of the planned economy, the WEDM machine not only has a high failure rate, but also has limited performance (only 50mm thickness can be cut, and the efficiency is 20~30mm2/min) but anyway Wire-cutting machine tools are unique to China's machine tools. Compared with wire-cutting machine tools from abroad, wire-cutting machine tools are less precise, but their manufacturing and operating costs are absolutely superior. They are very suitable for those developing countries. Due to the demand of this potential market, after the implementation of the market economy in China, a large number of wire-cutting machine tool manufacturers have emerged across the country. As a result, disorderly competition has emerged in the wire-cut market, and disorderly competition has evolved into price competition. In order to reduce costs, Some enterprises with poor technical skills have lowered their production standards, and the related technical supervision agencies of the country have not managed Force, the quality of the EDM different manufacturers on the market a huge discrepancy.
The
The key to wire-cutting machine tools is their accuracy. Because the machine tool is a “working machine”, only high-precision machine tools can produce high-precision machinery and further promote the refinement of products. Wire-cutting machine tools as a machine tool, high precision is the industry's constant pursuit of the goal. Although technical capabilities are strong, due to the disconnection from the market and the constraints of the planned economy, the WEDM machines not only have a high failure rate, but also have limited performance (only 50mm thick can be cut, and the efficiency is about 30mm?/min) but anyway This wire-cutting machine is a machine tool unique to China. Although it has a lower accuracy than the wire-cutting machine from abroad, its manufacturing and operating costs are absolutely superior. It is very suitable for those developing countries. It is precisely because of this potential market demand.
The
Judging from the social environment, China's implementation of the market economy is not a long time. Some small-scale wire-cutting machine tool manufacturing plants are still in the accumulation stage of the original capital. These manufacturers often do not have the entire machine manufacturing capacity, but only assembled production and production. The whole process of quality control is totally unsound, and R&D and innovation are even more impossible. The number of such manufacturers in the eastern part of China is very large, coupled with the immature laws and regulations that China and the market economy are currently supporting, as well as the benefits Driven by the protection of local governments, these unproductive enterprises will continue to survive. From the current status quo, the country’s attitude towards this is naturally eliminated through market competition. |
