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 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 o...

Aluminum alloy is currently a very common material in the parts processing industry, mainly because of its excellent physical properties and stable chemical properties. However, the precision machining of this material has always been a difficult point in the Cnc Machining process because of the cutting Factors such as stress and residual heat affect us, it is difficult to guarantee the quality of parts processing, and traditional three-axis machining equipment cannot guarantee the surface quality of processed parts. Today, the editor recommends five-axis machining of aluminum alloy parts. Let’s take a look below. The main application of this process.
1. Mould industry
Table of Contents
Most aluminum alloy molds can be made with three-axis machines, but the molds with complex shapes and undercuts cannot be used with three-axis machines. There is also a mold three-axis machine that requires a high curve in the design of high-end products and must give way to four-axis and five-axis. When expanding into the mold industry, if you want the movement of the workpiece to be like a three-axis machine, and only move on the horizontal plane without being affected by gravity, there are only two options for the five-axis machine model: double pendulum milling head type and one pendulum and one transformation.
2. Complex curved parts
This type of turntable can be used to make a large mold with a large load, because the workpiece only moves linearly in the XY plane and the rotating gravity has no effect on it. However, the linkage of the rotary table C and B pendulum milling heads plus a true five-axis machine XYZ can process any complex surface. In addition, the rotary table has only one C-axis. The manufacturing cost is significantly lower than that of the cradle, whether it is from the functional mechanical structure or from the precision manufacturing. Considering the difficulty, this five-axis machine should be the perfect model for processing molds.
3. Application in the field of daily necessities and industrial tools
The standard of living is improved with the improvement of production technology. More and more people in society are willing to pay for high quality and there is still a trend to raise the technical threshold to prevent counterfeiting. More and more kitchen supplies, high-end bathroom toys and decorations have adopted complex surface designs, and these four axes cannot be processed. Only the five-axis process can be used.
Judging from the current application situation, the five-axis machining process for aluminum alloy parts has rapidly developed in popularity. However, compared with the popularization process of three-axis machines, the popularization of five-axis machines should also be a breakthrough with the expansion of the scope of application. It is not just aluminum alloy that most of the other materials use five-axis processing to achieve much better results than other processes. Only when the advanced processing technology is fully popularized in the parts processing industry can it achieve longer-term development.
