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

The heat dissipation effect of the radiator has a great influence.

 The easier way to check the frame is to use the frame gauge. The frame gauge is actually a set of observation needles. During inspection, hang the frame gauges at several different positions on the frame. When using, the three gauges must be used at the same time. The more gauges, the more accurate. If the frame is not deformed, the side needles of the frame gauges should be aligned during the inspection. If the observation needles are not aligned, it means the frame has been deformed. Plate steel plates between the tools as shown in the figure to avoid local stress and deformation. If the frame is accurately inspected, you can use a plumb hammer to draw the frame on the floor. This work must be very precise. The floor must be level and clean. If necessary, paste or nail paper on the floor, and use a plumb hammer in the car. The measurement points on the frame are projected on the ground, and then the distance between the points on the ground is measured by pushing the car away, as shown in the figure. If the frame has been deformed, as long as the amount of error is not large, it is still possible to correct it. The method of calibration varies. Some regulations must be calibrated in a cold state, the reason is that heating will weaken the strength of the frame. There are also suggestions for heating and correcting the frame, but the temperature should not exceed the dark red at this time. Hard work at this temperature will reduce the strength of the frame material and cause permanent damage. Especially the components that have undergone heat treatment, pay more attention to it. When heating, the heating area should be minimized, and attention should be paid to slow cooling. So as not to make the material brittle. Usually an oxygen-acetylene flame is used to heat the frame. It is also necessary to use some straightening tools, such as a thick I-shaped beam connecting the I-shaped beam and the frame of the chain to apply pressure to the chain to correct the pressure of the jack, or special topping tools made of screws, etc. The pre-compression should be correctly selected when correcting the frame. Location. And in the frame and correction, if the frame is severely deformed or broken, the frame needs to be replaced.
