The key to wire-cutting machine tools is their accuracy. Because the machine tool is a “working machineâ€, 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.
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.
According to the characteristics of the process, there are two kinds of cyanide gold plating and cyanide gold plating: Jin Yuan. At present, the quality of gold plating is cyanide (potassium cyanide) gold plating is good, its color, adhesion, wear resistance are better than non cyanide gold plating. Function can increase the conductivity of the material. The appearance of gold plated layer, has high chemical stability, only soluble in aqua regia, insoluble in other acid. The valence of gold. The standard potential Au+/Au of monovalent gold is +1.68V, and the standard potential of trivalent gold is Au3+/Au at +1.50V. In the case of steel, copper, silver and its alloy matrix, the gold deposit is a cathodic coating.
Jin Yuankang gold plating layer good ductility, easy polishing, high temperature resistance, with good anti tarnish properties. Gold plating on the silver layer can prevent the discoloration of silver; gold alloy coating can show a variety of colors, it is often used as decorative coatings, such as plated jewelry, watches and parts, works of art, etc..
Jin Yuan Kang plated with low contact resistance, good conductivity, easy welding, strong corrosion resistance and good abrasion resistance (of hard gold), so the precision instruments, printed circuit boards, integrated circuit, shell, electric contact has been used.
