Single cut cnc wire cutting is a Chinese characteristic wire cutting
Domestic single cut cnc wire cutting machine is indeed a kind of edm wire cutting machine with Chinese characteristics. If the machine tool machinery for the host, regardless of the principle and structure, there is no great difference in nature. The advantages and disadvantages of various machine tools are reflected in the accuracy, stability and durability of precision, the degree of precision of mechanical processing, the quality and reliability of key parts. As for the disadvantages brought by rapid reciprocating wire feeding, no one has been able to make a breakthrough change in the mechanical structure of the main machine. And operation control system, there are generally as follows three categories: first, discrete components, has gradually faded out, accounting for the total social possession of 1% - 1. 5% with a low probability of opening. Second, the single-board machine, is the main force of the current service, accounting for about 85% of the total social holding, is the main force to complete the task of line cutting. Three, PC type, the realization of the integration of programming and control, graphics direct display and tracking, the realization of the full interface control, more convenient, more intuitive, the current popular version of about a dozen, there is no absolute advantage. PC type accounted for about 15% of social ownership.
Single board machine type control system so in the market, the main reason is: 1, single board machine functional resources are fully utilized, has become a single board machine application field of a masterpiece. 2, single board machine low price, high reliability. 3. Honed by the market, the technology is mature and perfect. 4. High awareness of the operator group, suitable for the thinking inertia of the operation team. The disadvantage of fast wire cutting is that in addition to manual programming, other programming means and wire transmission. No screen display and no graphics trace. Due to the limitation of data storage, the processing parameters cannot be directly modified and set digitally.
PC type control system has been recognized and praised by many users, the internal reasons are: 1, in line with the technology, especially the general trend of the development and application of computer technology. 2. With the ready-made machine configuration and operation platform, the manufacturer only needs to independently develop the program and system interface. 3, programming and machine control as one, saving transmission and storage concerns. 4. Timely and convenient color display system and graphic display tracking give users intuitive and credible feeling. 5. The convenience of transformation and upgrading is also appealing. Its disadvantage is that the vast majority of PC resources are not fully utilized. So that the natural use of the environment and power grid supply conditions become more demanding, the motherboard and the main accessories market to retain a short time. Make whole machine again batch production and repair difficulty.
It is estimated that single-board and PC control systems will coexist and compete for a long time.
In the future, the rapid wire cutting, molybdenum wire, rapid reciprocating wire will continue, the current cooling fluid will be changed due to the increase of environmental protection; Control will be more human, convenient, applicable to a wider range. Manual control box operation, even wireless manual control box will be widely adopted, and the process parameters will mainly focus on solving the five problems.
1. Stable accuracy above 0.01,
2. Desalination and unimpeded transformation of commutating stripes
3. Stable, practical and continuous cutting efficiency of 120mm2/ min or above,
4. Continuous wire like aluminum and steel,
5. Tension system suitable for fast reciprocating wire feeding.
6. The single cut cnc wire cutting small taper machine tool (6 degrees) is more convenient to operate, and the small taper function will become a standard accessory. Higher accuracy and stability. Large taper machine tool (more than 30 degrees) will be more specialized.
