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
Because Cnc Machine tools have the characteristics of strong adaptability, high machining accuracy, good quality, and high machining efficiency, they have been widely used. CNC technology has also become the most important technical foundation of modern advanced manufacturing technology and an important component of today’s advanced manufacturing technology. part. However, most of the hardware and software of CNC systems (represented by FANUC, SIEMENS, etc.) on the market are dedicated and incompatible with each other, and the system architectures are not the same, which results in different manufacturers' control systems. Relatively independent and closed to each other. With the advancement of technology and the intensification of market competition, the CNC system of this special architecture has increasingly exposed its inherent defects.
The large current should be greater than 200A. The response time of the WDTS device corresponding to this output characteristic is about 10is, which can already meet the dynamic requirements of the trimming system. For this reason, the main performance of the developed drive power supply is as follows: (1) The voltage is continuously adjustable from 0 to 300V; (2) The resolution is 100V; (3) The output stability of the power supply is high, the output voltage ripple is small, and the temperature drift is small; (4) ) Can realize automatic control.
3 Practical application In order to test the performance of this dressing system, an online dressing experiment of MEEC grinding wheels was carried out on the self-developed MEEC machining system. The system mainly includes: self-developed multifunctional compound grinder (which can realize compound processing of outer circle, plane, inner circle and tools).
Multi-purpose composite electric machining pulse power supply (can realize the power supply to the machining circuit and the grinding wheel dressing circuit; the pulse frequency and pulse width of the power supply are adjustable; the power is high and the efficiency is high; the application results show that the system can well become the online MEEC grinding wheel Automatic trimming, high precision, good reliability, sensitive response, small size, beautiful appearance, can be used as an important accessory of MEEC processing system.
