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

Talking about how to do the inspection and maintenance of tires

In the process of daily car use, most of the time we care about how to maintain the engine but ignore the knowledge of tires. As one of the important components of a car, the tire is not only related to the handling performance of the vehicle, but also to the personal safety of the occupants in the vehicle. Therefore, knowing more about tire knowledge is something that every car owner should have. How to do tire inspection and tire maintenance is one of the important foundations for safe driving.

For this reason, this newspaper specially invites the technical experts of Hubai Auto Service Chain Store to explain several points of attention to car tire inspection and maintenance to the majority of car friends.

1. First, check the air pressure of all tires on the car under cooling conditions at least once a month. If you find that the air pressure is insufficient, you should find the cause of the air leak. (Be sure to check the tire pressure after the tire has cooled down.)

2. Please check from time to time for bulges, cracks, cuts, nails and abnormal tire wear. If you find these conditions, you must immediately find a professional to check.

3. There is a wear indicator at the 1.6 mm depth of the tread groove. The wear indicator must be replaced when the tire is worn. It is dangerous to use tires that exceed the wear indicator, especially when driving on wet ground, because the drainage performance has been greatly reduced.

4. Regularly check the four-wheel positioning of the vehicle. If the positioning is found to be poor, correct it in time, otherwise it will cause irregular tire wear and affect the mileage of the tire. It is recommended to adjust the position every 8000 to 10000 kilometers.

5. Do not ignore the existence of the spare tire while doing daily tire inspection and maintenance. Be sure to check the inflation status of the spare tire regularly to maintain the standard pressure and avoid becoming a display at critical moments.

*Later, experts from Hubai Auto Service Chain Store also pointed out that Hainan is a tropical area with high ground surface temperature. When a car is driving, tires are not easy to dissipate heat. Friction with the ground will accelerate tire heating and increase tire pressure, which may easily cause tire safety hazards. . Therefore, pay attention to the temperature and air pressure of the tire when operating under high temperature conditions.
