The electric discharge wire cutting machine can be divided into high-speed reciprocating wire EDM wire cutting machine (commonly known as "fast wire"), low-speed one-way wire EDM wire cutting machine, (commonly known as "slow wire") and Three types of self-rotating electric discharge wire cutting machines. It can also be divided into a single column cross table type and a double column type (commonly known as the gantry type) according to the work table form. At present, the market demand is relatively large is the fast-moving and the middle of the wire. So what are their respective characteristics and performances?
Fast wire is also called high-speed wire EDM wire cutting machine. It is the main machine produced and used in China. It is the original EDM wire cutting mode in China. The electrode wire (usually using molybdenum wire specifications: 0.18mm, 0.2mm, 0.22mm, 0.25mm) reciprocates at high speed, the molybdenum wire speed is adjustable from 8 to 10m/s, the molybdenum wire can be reused, and the processing speed is fast. It is convenient and named (the precision is 0.05~0.08mm), and the molybdenum is stopped when the ratio is reversed, so that the processing quality is reduced (if the speed is proportional to the mass, the speed is faster, the quality is decreased (the surface is roughened), and the speed is slower (the surface is processed). It is the main machine produced and used in China, and it is the original EDM wire cutting processing mode in China.
However, after years of progress and development, the fast-cut wire cutting can be said to have a place in today's manufacturing industry. However, the fast-cut wire cutting is only a processing efficiency, and its smoothness and precision are poor. The surface of the cut workpiece is particularly obvious, but it can be satisfied for some products with low processing requirements, and the price is low, so it is low. The end market has a certain appeal.
The middle wire is also a kind of electric wire cutting machine. The so-called "medium wire" does not mean that the wire speed is between high speed and low speed, but a composite wire cutting machine. It is a reciprocating high speed wire EDM machine. The category is to realize multiple cutting functions on the high-speed reciprocating wire EDM machine, which is commonly known as “medium wire cutting”. The wire speed is automatically controlled by the system and can be adjusted as needed. High speed (8-12m/s) wire is used for roughing and low speed (1-3m/s) wire for finishing. This makes the work relatively stable. The vibration 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, and the processing quality can be between the high speed wire machine and the low speed wire machine.
The middle wire is a reference to the multiple cutting process, and has improved the process and accessories of the machine tool. Therefore, the wire is actually an upgraded version of the wire cutting. Generally, you may think that the middle wire may not feel fast and fast. In fact, the processing efficiency of the wire is not slower than that of the wire, and even its processing efficiency is much higher than that of the wire.
The above briefly describes some of the characteristics and performance of the fast wire and the middle wire. In fact, there are many choices in the market. There are stepping in the wire, servo in the wire, stepping high efficiency in the wire , servo high efficiency in the wire, we can choose according to different processing requirements. Suzhou is the birthplace of China Silk, and has gathered many well-known brands in China, such as Suzhou LongKai Electromechanical Technology Co., Ltd. , specializing in R&D and manufacturing of machine tools, which can be customized according to customer needs.
