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 bett...
The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...
Machining has always been a high-performance technology. my country has experienced a long period of industrial technology innovation and has a very strong industrial background. For the machining of some parts and the production of machines, my country no longer needs to rely on foreign technology. , We also have our own core technology, and the five-axis machining technology is such a very new technology, so where should we look for this kind of heatsink five-axis machining?
1.Choose a different way to proceed
Table of Contents
Regarding the five-axis machining of a heatsink at a reasonable price, we need to find a way that suits us. A five-axis machining tool for high and low light heat dissipation brackets for heatsink cars is provided, which includes a machine table, a machine base and an oil cylinder base. A rotating platform is installed between the machine base and the oil cylinder machine base, the servo motor connecting the main shaft and the rotating platform is installed on the machine base, and the main shaft control machine and the rotating platform are installed on the machine base. For the motor, a machining positioning fixture is installed on the rotating platform.
2. Choose the right tool for machining
The five-axis machining of heat sinks that can be praised by everyone. Generally speaking, true five-axis machining centers are suitable for surface machining, and 3+2 axis machining centers are suitable for plane machining. Most of the five-axis machining center does not require special fixtures during machining, which can reduce the cost of fixtures and avoid multiple clamping. Therefore, it is necessary to improve the accuracy of mold machining. The number of clamps used can also be reduced. Many special tools are omitted in machining, thereby reducing tool costs. In addition, the effective cutting edge length of the tool can also be increased during machining.
It lies in the aspects of machine production, especially in the machining of heatsinks. For this kind of heatsink five-axis machining technology, it has the advantages of higher machining efficiency and more energy saving. At the same time, this five-axis machining technology can also be applied to the production of more machine parts. Only the five-axis machining of heatsinks, which is relatively reliable and can be praised by everyone, is a good choice.
