The 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.

The solution to the problem of slow-moving wire cutting We are glad to share with you about the results of our work, company news, and give you timely developments and personnel appointment and removal conditions.

In order to meet the ever-increasing requirements for the manufacturing accuracy and surface quality of various stamping dies with precise structures, complex shapes and long service life, the slow-moving wire cutting processing technology has developed rapidly, gradually replacing the fast-moving wire processing technology in precision The original position in the field of mold making. 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.

Experts 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.

Compared 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.

WEDM Efficiency; Surface Quality; Machining Accuracy; Abnormal Problems According to the practical experience of slow-moving wire cutting for many years in mold enterprises, the abnormal problems in the processing efficiency, surface quality and machining accuracy of slow-moving wire-cutting are analyzed, and the specific measures to solve the problem are put forward. The cutting quality has an important guiding role.
