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
To say what is suitable for the processing technology of aluminum alloy parts, it must be non-five-axis processing technology. Compared with the traditional three-axis four-axis machine tool, the five-axis processing technology has obvious advantages, and its accuracy is higher. The processing speed is faster and it saves more tools. However, there are currently a large number of five-axis machining centers for aluminum alloy parts on the market. How should we choose?
1. Structure determines equipment performance
Table of Contents
Five-axis machining centers have various structures. The structural design of the machine tool determines the performance of the equipment on the basis of the machine tool, and determines the rigidity, accuracy, stability, operability of the machine tool, and so on. The following aspects should be considered: one is that the linear axis is not combined and superimposed when moving, the other is that the equipment with a short cutting circuit has good rigidity, the third is whether the tilt rotation axis is a DD motor, and the fourth is whether it is 5-axis linkage and 5-axis proximity, etc. .
2. Interference and collision avoidance
Interference avoidance is a problem that cannot be ignored in 5-axis machining. In addition to the use of computer-side software interference checking, the standard machine tool should also have the online real-time simulation CSG function to prevent interference even in manual mode. The online real-time simulation CSG function can check possible tooling errors or tool length setting errors before processing so as to reduce the emergency stop during operation to a smaller limit.
3. Rotation center correction
Changes in the rotation center caused by environmental and temperature changes will affect the five-axis machining accuracy. It should be automatically corrected by the probe. The 3-axis/index/5-axis machining accuracy verifies that the machining error of the tool is less than ±4μm. In order to ensure this, it is recommended to use the probe to automatically calibrate the 5-axis rotation center, and its linkage accuracy is a manifestation of multi-factor results.
Of course, the processing technology is also a key factor, which determines whether the performance of the equipment can be exerted to a greater extent. For example, our common use of special-shaped tools can greatly improve the processing efficiency. In addition, we all must pay attention to that is that the machining accuracy of the machine tool is directly affected by the accuracy of the rotation axis.
