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

How to solve the temperature rise of the water tank in summer cars

Now that the weather has gradually become warmer, it seems to be completely beyond the temperature that should be in an ordinary spring. And this shows that summer is coming. In the summer, the first thing every car owner has to face is the control of the car water temperature, so today this article will tell car owners about the method of heating the car water tank.

In summer, car owners are most concerned about the problem that the water tank boils because the weather is too hot, but this problem has been solved by antifreeze for car owners, but antifreeze cannot solve the problem of the temperature rise of the car water tank. Because the water temperature of the car is too high, it will easily cause the antifreeze to evaporate and then lack of water to affect the cooling system. So what should I do if the temperature of the car water tank is too high? Let’s take a look together.

The water temperature is abnormal when the air conditioner is not turned on

In summer, car owners must first determine whether the water temperature in the water tank is rising normally. Under normal circumstances, it should be like this. First, confirm whether the liquid level in the coolant replenishment tank is appropriate; then start the engine and observe the water temperature gauge, and the water temperature gradually rises.

After turning on the air conditioner, the water temperature is too high

Under normal circumstances, the water temperature in the water tank of the car should decrease as the air conditioner is turned on, but if the water temperature is too high after the air conditioner is turned on, what should be done when it is not turned on? First of all, the owner should first judge that there is no problem with the coolant, thermostat, thermal switch, fan, insurance and water pump. After the electric fan stops, turn on the air conditioner switch, and the fan should run immediately. The fan should run at a higher speed when the throttle is increased to above 2000 rpm of the engine.

The normal driving water temperature of the car rises

In summer, if the car owner finds that the temperature in the water tank is constantly rising or the red light of the water temperature gauge is flashing when the car is driving, then the owners should first find that the red light is flashing when the car is driving. The pointer is normal to determine where the fault occurs.

Summary: The above is what the editor told car owners today about how to solve the heating of the water tank in car maintenance. If you have encountered such a thing in summer, then I hope this article can be helpful to you.
