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

Study car vibration and noise

Studying the vibration and noise of automobiles and taking effective measures to control them has also become extremely complicated. At present, effective control measures have been taken to control the internal noise of gasoline and diesel vehicles, while the problem of identifying and controlling noise sources of new energy vehicles such as hybrid vehicles, electric vehicles, and fuel cell vehicles will become a problem for researchers. New subject. Each test will provide effective feedback to optimize the design at this stage. These verification tests and design optimization are repeated to determine the structure of the catalytic converter.

Taking a fuel cell prototype vehicle as the research object, through the experimental analysis of its acoustic and vibration characteristics in the anechoic chamber, the main frequency components of the noise in the vehicle under static and different uniform speed conditions and the corresponding noise sources and their transmission methods are obtained. The corresponding vibration and noise reduction schemes are proposed.

Introducing the noise sources in the car The vibration and noise generated by the driving motor assembly, power steering pump, air-conditioning compressor, fuel cell auxiliary system moving parts (such as hydrogen pump, fan) and cooling water pump of the fuel cell prototype vehicle studied are inside the car The main source of noise. Among them, the drive motor assembly, power steering pump, air-conditioning compressor, and fuel cell cooling water pump are arranged in the front compartment, and the hydrogen pump and fan are arranged in the luggage compartment. Because the prototype car borrows the traditional engine front car body, the rear part of the body does not adopt sound insulation measures, when the fuel cell power system is working, the occupants in the rear seats obviously feel a low “buzzing” roar, and the rear seats The noise is significantly higher than the front seats.
