Working principle of slow wire processing

 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

Hydrostatic guideway of CNC machining lathe

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

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

What details should be paid attention to in the processing of CNC lathe parts ​

In fact, what a workpiece can see is not only the strength of a manufacturer, but also its handling of some details.

For CNC lathe parts, if the cnc manufacturer does not handle it well, then this machining part is not acceptable.



What should the manufacturer pay attention to when cnc machining?

  • 1. The burr on the cost surface can be said to be easily overlooked by many manufacturers. Many people say what this part looks like when it comes out, and what it looks like when the finished product is packaged. In fact, for a part, the CNC lathe 5 axis cnc machining parts are completed by equipment, then the cloak will be produced during injection molding, and this burr is also produced at this time. If it is not trimmed in time, or the The parts are obsolete. Otherwise, it will affect other links during use.
  • 2. Accuracy of parts. For CNC lathe machining parts, its accuracy is very strict. It can only be used if it meets the required accuracy. The accuracy of the part is judged mainly by its control of the size. Ability, if it is within the tolerance that can fluctuate, then the part is qualified, if it is out of tolerance, then it is unqualified.
  • 3. Analysis of the test results. For china mfg component, it will inevitably undergo a performance test before it leaves the factory. If the performance is qualified, it will be shipped out. If it is not qualified, then it should be analyzed. In this way, it can also avoid mass scrapping. Manufacturers in the machining industry will basically deal with it in this way. They will make certain quality control charts based on the performance of many companies to analyze the reasons.
