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
The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200 beryllium copper and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette
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
Aluminum alloy is a very good material for parts. Its low density can achieve lightweight parts and its strength is very high even comparable to steel. In addition, its corrosion resistance, electrical conductivity and thermal conductivity are very good. But there is a major defect that precision machining is very difficult, but the emergence of five-axis machining technology has solved this problem well. Today, let’s take a look at the advantages of five-axis machining of this aluminum alloy part.
1. Reduce processing time
Table of Contents
In the processing, the flat-bottomed end mill is used to maintain the vertical surface of the complex mold processing surface, which can greatly reduce the processing time. It is also suitable for side milling with angled surfaces, which can eliminate the rib-like shape caused by the spherical end mill processing. The texture makes the surface quality of the aluminum alloy mold more ideal and reduces the workload of manual milling and manual work required to clean the mold surface.
2. Improve processing accuracy
Through this technology, the problem that the workpiece needs to be repositioned at a complex angle and needs to be debugged multiple times can be solved not only shortens the time, but also greatly reduces the error generated, and the large cost of tooling and fixtures required when installing the workpiece It also saves money and the machine tool can also add complex parts, such as the drilling taper processing cavity recesses required for complex surfaces, which cannot be achieved by traditional methods.
3. High production efficiency
It can effectively reduce the processing time and auxiliary time of the parts. The range of the spindle speed and feed rate of the linkage machining center is large, allowing the machine tool to perform powerful cutting with a large amount of cutting. At present, when this technology is entering high-speed machining, the rapid movement and positioning of moving parts And high-speed cutting reduces the turnaround time of semi-finished products and improves production efficiency.
In addition, this kind of five-axis machining equipment for aluminum alloy parts is relatively easier to realize intelligence. At present, network-based mobile control methods such as tablet computers, mobile phones and wearable devices will become more and more popular. This type of operating device can quickly react to switch screens, uploading or downloading data, and significantly reduces the misoperation rate. Compared with traditional three-axis and four-axis machine tools, this kind of five-axis linkage equipment is undoubtedly more capable of achieving automation.
