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...
Elimination of Gear Backlash in CNC Machining Feed System The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap. 1. Rigidity adjustment method The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity. (1) Eccentric shaft adjustment method As shown in Figure 610, the...
How are the CNC Machining Manufacturers in Shenzhen? China Hardware Has Carried out Comprehensive Comparison with Multiple Dimensions in Various Regions
Keywords:Cnc Machining manufacturers,CNC Machining,How about Shenzhen CNC Machining manufacturers
I'm not afraid of the quality of the product, I'm afraid to shop around. There is no contrast and no injury, this has been known to everyone since ancient times. For example, Shenzhen CNC Machining manufacturers, if you can find more Shenzhen CNC Machining manufacturers to compare their products, and compare the strengths of Shenzhen CNC Machining manufacturers, you will find that what you see with the naked eye is not all right, there may be some Unidentified objects participate in it, how do you compare them, and what aspects should you start with? Let's see how you do it.
Everyone says to shop around. So, what is the comparison? Here is an explanation. Duowei Shenzhen is looking for suitable Shenzhen manufacturers for CNC Machining: 1. There are various qualification certificates: such as: business license, ISO, equipment distribution, environmental quality system, etc., whether these certificates are complete; 2. Commercial channels: learn more about the channels of manufacturers, whether there is a single supply situation, if there are more channels, it means that the CNC Machining manufacturers have certain processing experience. 3. Technical support: depends on the strength or the CNC Machining technology, the technology is excellent, the product can be flawless, if you don't do it, there will be a lot of leakage.
Each dimension revolves around the dimension of finding a Shenzhen CNC Machining manufacturer that suits you. The starting point is the starting point. The higher the matching degree, the more suitable it is. Therefore, no matter what you buy, you must make a comprehensive comparison. If you don't have this action, then you will lose not only the gap in quantity, but also the gap in quality. The above is the valuable experience summarized by Shenzhen CNC Machining manufacturers over the years, and I hope it will be helpful to everyone.
