What should be paid attention to in the working environment of the medium wire machine?

1) The characteristics of the wire-cut discharge machine, there is dust in the air, which will cause the screw of the machine to be seriously worn, thus affecting the service life;

2) The wire-cut discharge machine belongs to the computer control, the disk used by the computer has quite strict requirements for dust in the air, when the dust enters the disk, the disk will be damaged, and the hard disk will also be damaged;

3) The wire cutting discharge motor itself emits a lot of heat, so the electrical cabinet needs to be ventilated frequently, if there is too much dust in the air, it will be attached to each electrical component during the ventilation process, resulting in poor heat dissipation of the electrical components, resulting in the circuit board being burned out. Therefore, the dust filter of the machine should be cleaned frequently.

2. Choose a place that can bear the weight of the machine tool;

3. Choose a place where there is no vibration and shock, wire cutting discharge machine tool is high-precision processing equipment, if there is vibration and impact in the place, it will cause serious damage to the machine, which will seriously affect its processing accuracy, shorten its service life, and even lead to the scrapping of the machine.

4. Meet the space size required by wire cutting machine tools;

5. Choose a place with little temperature change, and avoid direct sunlight through windows and top window glass and close to heat flow.

1) The products processed by high-precision parts need to be carried out at a constant temperature, generally at room temperature of 20C;

2) Since the wire cutting discharge machine itself generates considerable heat when working, if the temperature changes too much, it will have a serious impact on the service life of the machine.

6. Choose a shield house: Because the wire cutting discharge process belongs to the arc discharge process, strong electromagnetic waves will be generated in the arc discharge process, which will cause harm to human health and affect the surrounding environment

7. Choose a spacious workshop with good ventilation conditions, so that the operator and the machine tool can work in the best environment.

Other precautions for wire cutting:

1. A certain gap must be maintained between the molybdenum wire and the surface to be processed of the workpiece, and the width of the gap is determined by the processing conditions such as working voltage and processing volume.

2. The high insulation is required in order to facilitate the generation of impulsive spark discharge, and the voltage between the two poles cannot penetrate the medium between the poles.

3. Pulse power supply must be used, that is, the spark discharge must be pulsed and intermittent, and in the above figure, TI is the pulse width, TO is the pulse interval, and TP is the pulse period. In the interval between the pulses, the gap medium is ionized so that the next pulse can be discharged between the poles.

Wire cutting machine originated in the early 70s of the 20th century, before the implementation of the market economy, the development of wire cutting machine tools was relatively slow, mainly because China's electronics industry was relatively backward at that time, and the production plants of wire cutting machine tools were state-owned enterprises.

Although the technical ability is strong, but due to the disconnection with the market, coupled with the constraints of the planned economy, the production of wire cutting machine tools not only has a high failure rate, but also has limited performance (can only cut 50mm thick, the efficiency is about 30mm min) but in any case this wire cutting machine tool is a unique machine tool in China, it is lower than foreign wire cutting machine tools, but its manufacturing and use costs are absolutely advantageous, for those developing countries is very suitable, It is precisely because of the demand of this potential market.

After the implementation of the market economy in China, a lot of wire cutting machine tool manufacturers have emerged in the country, so there is disorderly competition in the wire cutting market, disorderly competition has evolved into the best competition, in order to reduce costs, some enterprises with poor technical strength reduce production standards, coupled with the relevant national technical supervision agencies management is not effective, so that the quality of wire cutting machine tools of different manufacturers on the market is hugely different, the same wire cutting machine tools can be used for 10 years without attenuation, and some can only be used for two years, The same specification of wire cutting machine tools can be 100,000 yuan difference, which does cause great difficulties to the selection of users (especially foreign users), a little bit will be fooled, so why can these unqualified wire cutting machine tools appear in the market?

The popularization of wire cutting applications in the manufacturing industry, the application of wire cutting machine tools is not only limited to mold manufacturing, but also the rough processing of most mechanical parts is also using wire cutting machine tools, so low-grade wire cutting machine tools also have a certain market. Another reason is that GB7926-87 wire cutting machine tool accuracy standards clearly stipulate: before reaching this standard, we must first reach JB2670-82 "General Principles for Precision Inspection of Metal Cutting Machine Tools", and some incapable production plants exploit the loopholes of the national standard, they ignore the JB2670-80 national standard, reduce the processing accuracy in the production process and choose inferior materials, so there is a complete loss of accuracy after 1-2 years as mentioned above.

From the perspective of the social environment, China's implementation of the market economy is not long, some small wire cutting machine tool production plants are still in the accumulation stage of primitive capital, these manufacturers often do not have the whole machine manufacturing capacity, can only be assembled production, the quality control of the whole production process can not be talked about at all, research and development, innovation is even more impossible, such manufacturers in the eastern region of China is very much, coupled with the current China and the market economy supporting the law is not mature, as well as because of the interests driven by the local protection, Therefore, these enterprises without production capacity will continue to survive, and from the current situation, the country's attitude towards this is naturally eliminated through market competition.

The working principle is to use a continuously moving molybdenum wire wire (called electrode wire) as an electrode to carry out pulse spark discharge to abrode the metal and cut the workpiece. Its wire speed and workpiece quality are between fast wire and slow wire, so it is called medium wire, to be precise: medium wire is an upgraded product of fast wire, so it can also be called:

Rapid wire that can be cut multiple times.

Medium wire cutting machine tool is a kind of EDM wire cutting machine tool, including medium wire, slow wire and fast wire.

The wire machine tool is an original electrical processing machine tool created by our country, which has a wide range of applications in the field of mold manufacturing and parts processing, and occupies a considerable weight in the low-end market. At present, how to develop the wire machine is a topic of great concern to the electrical processing industry. We must learn from the success of foreign countries, develop our strengths and avoid weaknesses, directly apply the latest achievements of today's computer technology, develop a powerful PC-based numerical control system as soon as possible, and lay a good foundation for the development of wire machine tools from the hardware; At the same time, pay attention to the combination of artificial intelligence technology and high-speed wire cutting machine, and use computer software technology to improve the performance of machine tools.

In addition, strengthen the research of the machine tool body and carry out the application of multiple cutting technology, so that the overall processing level of the machine tool has a greater improvement, and constantly enhance the competitiveness of the high-speed wire cutting machine in the market. While using new technologies and new processes, we must also pay attention to the in-depth and detailed basic theoretical and experimental research on the laws of EDM wire cutting technology, which is also a very important link.
