Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Qualitative Analysis of Comparing Heat Dissipation of Radiator with Engine Heat Dissipation

Calculated according to the results of the radiator performance test, it can be calculated from the engine parameters, so the installation efficiency of each basic car model can be calculated. When designing an improved design or a modified car design, the cooling constant can be calculated with a known tool. The installation efficiency is obtained from the test, which is closer to the actual situation, while the cooling constant can be directly calculated and compared with the test result. This can quantitatively analyze the cooling capacity of the cooling system, replacing the previous qualitative analysis that approximates the comparison between the heat dissipation of the radiator and the heat dissipation of the engine. To this end, a cooling performance calculation program was compiled, as an example, to illustrate the calculation method of L cooling performance, and compare it with the test results.

Cooling system design calculation and test comparison example In the design of the rear passenger car, the above-mentioned arrangement is adopted. In the calculation, it has the same engine and similar engine system arrangement. Therefore, the installation efficiency can be calculated first according to the results of the cooling performance test, and the cooling constant can be calculated by quoting it in the design one calculation. The cooling performance test is carried out on the drum test bench, and the calculation result and the cooling performance test comparison table are compared to the cooling performance calculation and the test result. :The calculated value of the lJ constant l test value of the rotational speed ambient temperature cooling is compared with the test results, which shows that the new cooling performance calculation method is closer to the test value, which more truly reflects the cooling performance, and can be used in future cooling system design widely used.
