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
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 gear 1 is mounted on th
Keywords: Cnc Machining,CNC machining manufacturers,Which CNC machining manufacturer is better for cnc machining
Today, Mr. Yi shared a poor case, saying that when the company urgently needed parts, it found a CNC machining manufacturer, and the result was pitted. The reason is that there is no after-sales service after the CNC machining manufacturer's products are made, and it is still There are constant problems, which makes Mr. Yi very anxious, saying that there are so many CNC machining manufacturers now, which one is better? With such a question, let me explain it below.
Every choice may be right, but it may also be wrong, but the standard of my own measurement is different. Judging from the question of which CNC machining manufacturer is better, Yi always fails to find the right one, otherwise such a problem will not arise. Each CNC machining manufacturer has its own accounting standards, but the accounting methods are different. Some are calculated according to the customer’s drawings and needs, and some are calculated according to the customer’s general intention. In order to ensure the cost, some alternative materials will be used, so For the problem of Mr. Yi, if you can select and calculate the CNC machining process according to the drawings provided by the customer, then such a problem will not occur.
It can be seen that no matter what you choose, you must be cautious and not blind your eyes because of some petty gains. Which CNC center is good is not only the quality, but also the character. If the character is not good enough, no matter how good the product is, it is useless. To describe it in the words of an employee, it is to find a CNC center, find one that you can understand, rather than find a hidden one. For YIJINHardware, choose a good one, don’t choose an expensive one, choose a simple one, don’t choose a complicated one.
