As the key equipment for the conversion of electrical energy and mechanical energy, motors are widely used in mining, metallurgy, oil and gas, petrochemical and other industries in the manufacturing industry. The growth is also highly related to the prosperity of the manufacturing industry. Industrial motors account for a large proportion of motors. According to the National Bureau of Statistics, China's industrial motor output will reach 346 million kilowatts in 2021, a year-on-year increase of 7%. With the continuous advancement of the recovery of my country's manufacturing industry and the recovery of the global economy, the demand for my country's industrial motors is expected to further expand. Output and growth rate of industrial motors in China from 2016 to 2021
Read MoreThe middle wire is also a kind of wire EDM machine. The working principle is to use the continuously moving molybdenum wire (called the electrode wire) as the electrode to perform pulse spark discharge on the workpiece to remove metal and cut into shape. The quality of the processed workpiece is between the two, so it is called the middle wire. To be precise: the middle wire is an upgraded product of the fast wire. It can be understood as: the fast wire that can be cut many times, but its processing and cutting speed is not faster than the fast wire. The wire is slow, but it is higher than the fast wire. Only in the process of multiple cutting, the cutting speed can be reduced to achieve the cutting effect. At this time, the average efficiency is calculated, not the highest efficiency, and the processing quality tends to be slow. Silk. The wire running speed is automatically controlled by the system and can be adjusted as needed.

With the improvement of process indicators in all aspects of this technology, it is playing an irreplaceable role in production by other processing technologies. The main advantages of slow-moving wire processing technology include the following aspects.
Read MoreExperts pointed out that the so-called "medium wire travel" does not mean that the wire travel speed is between high and low speeds, but a composite wire cutting machine, that is, the principle of wire travel is to use high-speed (8-12m/s) wire travel during rough machining. , Low-speed (1-3m/s) wire feeding is used for finishing, so that the work is relatively stable and the jitter is small, and the error caused by material deformation and molybdenum wire loss is reduced by multiple cutting, so that the processing quality is relatively improved. It can be between high-speed wire feeder and low-speed wire feeder. Therefore, it can be said that the user's "intermediate wire travel" is actually a reciprocating wire EDM wire cutting machine that draws on the processing technology of some low-speed wire travel machines, and realizes stripe-free cutting and multiple cutting.
Read MoreCompared with ordinary wire cutting, the processing cost of slow-moving wire cutting is significantly higher. On the one hand, this is because the price of the slow-moving wire cutting machine itself is relatively high. Another important reason is that the electrode wire used in the slow-moving wire cutting is one-time use, and it will be invalid after one pass, and cannot be like ordinary wire cutting. Use the wire electrode repeatedly. Therefore, in order to reduce the processing cost in the process of use, it is mainly necessary to start from the two aspects of improving the processing efficiency and saving the electrode wire.
