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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

How to solve the poor heat dissipation of automobile engines and air conditioning systems

Car engine and air-conditioning system have poor heat dissipation, resulting in excessively high water temperature. The following fault phenomena and solutions will occur: 1. When the traffic is not smooth-traffic jam or long idling, the engine water temperature gauge shows too high, and the electronic fan works in high-speed gear. If it is too long, the engine noise will increase. If the temperature is too high, the malfunction* will be obvious when the air conditioner is turned on.

Solution: After the car is hot, check the water return of the return pipe at the upper end of the antifreeze storage tank. If the return water is not smooth or blocked, the water temperature will be too high.

Reminder: Do not blindly disassemble and replace parts during maintenance.

2. When the air temperature is too high and the air conditioner is turned on, the idling speed is unstable and the speed fluctuates too much, the acceleration is weak, and the engine makes abnormal noise.

Solution: Check whether there is too much dust between the condenser and the water tank, and clean it thoroughly with high-pressure air to ensure that the water tank and the condenser have good heat dissipation performance.

Reminder: usually pay attention to wipe the dust between the condenser and the water tank.

3. After a hot car is turned off for more than ten minutes, it is not easy to start the car; when a hot car is running, it will sometimes turn off automatically.

Solution: When the car is hot, check the temperature difference between the upper and lower water pipes of the water tank. If the temperature difference is too large, you need to check the opening of the thermostat and whether the water pump has rotation speed failure.

Reminder: The temperature difference between the upper and lower water pipes of the water tank should not be too large.

4. When the car is cold, the air-conditioning refrigeration temperature is very cool, and the cooling effect of the air-conditioning is not obvious when the car is hot; and there is a large resonance hum in the air-conditioning system.

Solution: Due to the irregular addition and replacement of antifreeze, the engine water channel and water tank will be blocked in advance and the water temperature will be high. The antifreeze is replaced once every two years, and original parts must be used when replacing and adding.

Reminder: After adding water to the engine cooling system, or the concentration of the added antifreeze exceeds 60%, it will cause the water temperature to be too high.
