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

Summer car air conditioning maintenance method

Summer is here, and the car air conditioner is the owner's intimate partner, but if you don't understand it and don't maintain it properly, this intimate partner will often play anger and even hurt the owner's body. And the car air conditioner is easy to be damaged during the peak period*, so we must pay attention to the reasonable use of the car air conditioner, and do a good job in the maintenance of the car air conditioner.

Comprehensively check the air conditioner When you use the air conditioner for the first time in summer, you should check the air conditioner system first. For example, check whether the refrigerant fluid and the air conditioner filter element are dirty through the liquid storage tank, and whether there is foreign matter on the radiator.

Pay attention to the cleaning of the air conditioner. Don't wait until the air conditioner is not effective before you think about cleaning the air conditioner. The air conditioner filter should be replaced regularly, because there are more dust in the spring of Zhengzhou and the catkins will fly. These will stick to the filter, which is easy. Bacteria grow and the air conditioner produces a musty smell, so it is best to replace it once a year after spring. In addition, the condenser must be cleaned regularly, and the water tank must be removed for thorough cleaning.

After parking, do not turn off the air conditioner. Generally, car owners turn off the air conditioner and door and leave directly after arriving at the destination. In the hot summer, the huge temperature difference between the inside and outside of the car will cause the air-conditioning system to become moldy, which in turn breeds mold. Therefore, the car owner should turn off the air conditioner a few minutes before arriving at the destination, and turn on the natural wind, so that the temperature in the air-conditioning duct will rise, eliminate the temperature difference with the outside, so as to keep the air-conditioning system relatively dry and avoid mold growth.

Regularly open high air volume Some car owners do not like the noise made when the air conditioner is turned on to high gear, so they rarely or never turn on the air conditioner to high air volume. However, when the air conditioner is in use, a lot of dust will be sucked in. Regular high wind can blow out the floating dust on the inner surface of the air duct of the air conditioner. This is a simple way to keep the air conditioner clean. In addition, a dedicated air duct cleaning fluid should be used for sterilization, cleaning and deodorization.
