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

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

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

To ensure that the vehicle is effectively maintained under the state of the diagnostic system

The requirements for the reliability of vehicle equipment should be determined according to the conditions of ensuring safety or the conditions of cost optimization during vehicle equipment manufacturing and operation. When designing a new type of passenger locomotive by the “Main Line” Vehicle Manufacturing and Design Bureau Joint Stock Company, it used to ensure the reliability of the vehicle equipment from the perspective of ensuring safety, especially the safety of the system that has an impact on the determination of the continuous working failure-free rate index. The level was assessed. The control system and the diagnosis system have become the first step in the use of automatic data detection. They are used to provide continuous detection and assessment of the technical status of the vehicle equipment, and are used to provide analysis and transmission from the running train to the fixed station of the technical maintenance. Information about equipment failure and damage. It should be pointed out that the use of instrumental detection is the best method in some cases, for example, when tracking some fast-changing damage tendency process, because the process of detection may have to be continuous.

In order to ensure the effective maintenance of the vehicle under the condition of the diagnostic system, it must have the function of automatically predicting the failure of the bogie, automatic coupler, and braking device. In order to solve these problems, new diagnostic techniques should be researched and adopted. For example, in order to detect the status of brake shoes, many foreign companies use video monitors to transmit information to electronic computers. The method of using perspective to discover and detect the expansion of cracks belongs to the acoustic emission method, which is based on the principle of measuring sound radiation to form oscillations at the cracks, and has been successfully applied in many sectors of the machinery manufacturing industry. As pointed out above, not all damage to the vehicle equipment system will lead to the failure of the entire vehicle. Therefore, the choice of reliability level and maintenance method is suitable for the result of implementing the total cost * reduction. See the procedures for selecting equipment technical management and maintenance methods.
