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 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 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
Earlier, we introduced to you where the main advantages of precision parts processing are reflected. Today https://cncmachining.wiki/ will introduce some methods to improve the efficiency of precision parts processing:
In the processing of non-standard equipment parts, common problems such as accelerated tool wear, poor processing appearance, and difficulty in chip removal will occur. This has seriously affected the quality, production cycle and processing cost of precision parts of such materials.
The processing of non-standard equipment parts requires super-lubricated processing appearance and high processing accuracy, which requires the knife to have a high standard life. Whether the tools of CNC precision processing plants are worn or not will be based on whether the processing surface quality is reduced or not. The standard life of diamond tools is very high, and the tool wear is very slow during high-speed cutting. Therefore, the cutting speed is not restricted by the tool life during ultra-precision cutting, which is different from the general cutting rules.
The cutting speed selected for non-standard equipment parts processing practice is often selected according to the dynamic characteristics of the ultra-precision machine tool used and the dynamic characteristics of the cutting system, that is, the speed with the smallest vibration is selected, because the surface roughness is the smallest and the processing quality is at this speed. The highest, to obtain high-quality non-standard machining appearance is the primary question for non-standard equipment parts processing. Good quality, especially good dynamic characteristics, ultra-precision machine tools with low vibration can use high cutting speeds and increase processing power.
The selection of processing parameters of non-standard equipment parts mainly includes the selection of cutting tool viewpoint, the selection of cutting speed, the selection of cutting depth and feed speed, etc. From past experience, we know that if you choose a larger rake angle when processing plastic materials The tool can effectively inhibit the formation of built-up edge. This is when the rake angle of the tool increases, the cutting force decreases, the cutting deformation is small, and the contact length between the tool and the chip becomes shorter, which reduces the basis for the formation of built-up edge.
