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

Precautions for replacing car wheels

 

The size and width of the wheel hub are a set of very important data. The larger the size, the thinner the tire should be, because the tire circumference should be kept as long as possible, otherwise the speedometer will have deviations. The thinner the tire, the more obvious the feeling on the road. The wider the wheel, the wider the tire that can be installed. Although it will increase fuel consumption, the larger the contact area, the more stable the grip. Friends who consider the performance of the car should reasonably replace the wider tires.

Taboo for replacing the wheel hub:

One uses a wheel that is too big

Many people think that as long as the wheel hub is installed without touching the outer plate, it is ok. In fact, remove the wheel and take a closer look at the structure inside. There are many places where it is very easy to get stuck, especially when the car is started. compression. Therefore, if you change the big wheel hub, you must use it appropriately, and you can’t drive the car after you can’t blindly seek beauty. Also pay attention to the width of the rim.

The second brake caliper stuck to the rim

Due to safety issues in current production cars, large brake calipers are often used. 4pot calipers are much larger than singlepot calipers.

In such cases, insufficient offset and inappropriately designed rims often get stuck in the brake calipers. Fortunately, it’s easy to find in this situation. Once it is installed, there is a rubbing sound when the wheels are running, so change it quickly.

Three is the tire width

When you run, you must carefully observe whether there is any wear caused by friction on the inner and outer sides of the tire. A tire that is too wide can easily be caught by some parts.
