Difference Between Medium Wire And Wire Cutting

                                                           The full name of wire cutting is electric spark wire cutting, which is developed on the basis of electric spark perforation and forming. It not only develops the application of electric spark machining, but also replaces electric spark punching and forming machining in some aspects. Nowadays, wire cutting machine tools account for more than half of electric spark machine tools, widely used in mold, electronic instruments, precision machinery, auto parts, military industry and other industries.

The electric spark wire cutting machine can be divided into high-speed reciprocating wire cutting machine (commonly known as "fast wire cutting machine"), low-speed unidirectional wire cutting machine, (commonly known as "slow wire cutting machine") and vertical self-rotating electric spark wire cutting machine according to the wire cutting speed. It can also be divided into single-column cross worktable type and double-column type (commonly known as gantry type). At present, fast wire and medium wire are the most needed in the market. What are their respective characteristics and performances?

Fast wire cutting is also called high-speed wire cutting machine tool. It is the main machine type produced and used in China and the unique processing mode of electric spark wire cutting in China. The electrode wire (commonly used molybdenum wire specification: 0.18mm, 0.2mm, 0.22mm, 0.25mm) moves back and forth at high speed. The speed of molybdenum wire is adjustable at 8-10m/s. The molybdenum wire can be reused. The processing speed is convenient and named (its accuracy is 0.05~0.08mm). When molybdenum ratio is reversed, pause will reduce the processing quality (if the speed is proportional to the quality, the speed will be fast and the quality will be reduced (the processing surface will become rough), the speed will be slow and the quality will be increased (the processing surface will become bright). It is the main machine type produced and used in China and the unique EDM wire cutting processing mode in China.

But after so many years of progress and development, fast wire cutting has taken a place in today's manufacturing industry. However, fast wire cutting is only fast in processing efficiency, but its finish and precision are poor, and the cut workpiece surface line is particularly obvious. However, for some products with low processing requirements, it can meet the requirements, and the price is low, so it has a certain attraction in the low-end market Medium wire cutting is also a kind of electric spark wire cutting machine tool. The so-called "medium wire cutting" does not mean that the wire cutting speed is between high speed and low speed, but the composite wire cutting machine tool. It belongs to the category of reciprocating high-speed wire cutting machine tool. It realizes multiple cutting functions on the high-speed reciprocating wire cutting machine, known as "medium wire cutting". The wire feed speed is automatically controlled by the system and can be adjusted according to the needs. High speed (8-12m/s) wire feed is adopted for rough machining and low speed (1-3m/s) wire feed is adopted for fine machining. In this way, the work is relatively stable, the vibration is small, and the error caused by material deformation and molybdenum wire loss is reduced through multiple cutting, so that the processing quality is relatively improved. The processing quality can be between high speed wire feed machine and low speed wire feed machine.

The medium thread cutting refers to the multiple cutting process and improves the process and accessories of the machine tool. Therefore, the medium thread cutting is actually the upgrade of fast thread cutting. Generally speaking, people may think that the efficiency of medium thread may not be as fast as that of fast thread. In fact, the processing efficiency of medium thread is not slower than that of fast thread, and even its processing efficiency is much higher than that of fast thread.

The characteristics and performances of fast and medium filament are briefly described above. In fact, there are many choices of medium filament in the market, including stepping medium filament, servo medium filament, stepping high efficiency medium filament and servo high efficiency medium filament, which can be selected according to different processing requirements.
