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
Five-axis processing of plastic parts is a more commonly used form of processing now. It can process complex-shaped parts that ordinary machine tools cannot process. However, when using five-axis processing, you also need to master the corresponding technology, otherwise you will be processing complex parts. Quality problems are prone to occur when
1. Compile the tool program
Table of Contents
Although the tool length compensation function in five-axis machining is still effective, the tool radius compensation is invalid. This is because the ISO file does not provide enough data to recalculate the tool position. Therefore, in order to ensure reliable machining quality, it is necessary to compile different programs for different diameters of the tool when performing five-axis machining.
2. Use post processor
The difference between five-axis and three-axis machine tools is that there are two rotating coordinates on the five-axis machine tool and the tool position is converted from the workpiece coordinate system to the machine tool coordinate system, and the coordinates need to be changed several times in the middle. With the help of the current popular post processor generator, the post processor of a three-axis Cnc Machine tool can be generated only by inputting the basic parameters of the machine tool. For five-axis CNC machine tools, there are currently only some improved post-processors and the post-processors of five-axis CNC machine tools need to be further developed.
3. Solve the problem of nonlinear error and singularity
The kinematics of five-axis machining after the introduction of rotating coordinates is much more complicated than that of three-axis machine tools. One of the main problems related to rotation is the nonlinear error and it belongs to the programming error. In order to avoid this error, the programmer cannot know the size of the nonlinear error in the pre-calculation stage. Only after the machine tool program is generated by the post processor, the nonlinear error It is possible to calculate the error.
Although five-axis machining has more advantages than ordinary machining methods, in order to avoid the inefficiency of the entire machining process and the unsatisfactory quality of the machining, when using the five-axis machining of plastic parts, everyone should program the tool first. After that, we must make good use of post-processors and solve problems such as non-linear errors.
