The following offers an analysis as well as some direction regarding these frequently held misconceptions.It is common for the workpiece to be overlooked when the electrode is used to touch it.
Surface contact refers to a method that involves the electrodes making direct contact with the workpiece.There will invariably be more or fewer fine objects between the contact surfaces, and there will also be clamping accuracy errors on the contact surfaces. Both of these factors will directly influence how accurately edge finding and centering are performed.When utilizing this method, it is imperative that the contact surface be wiped down thoroughly to ensure cleanliness; however, because there are human factors involved, the accuracy will be unreliable.
1) Clamp the workpiece; 2) Set a reference ball on the workbench; 3) Install the probe on the spindle head; 4) Make use of the probe to center the workpiece; 5) Make use of the probe to center the reference ball; 6) Remove the probe and install the electrode; 7) The subsequent electrodes are all centered on the reference ball.

Due to the fact that the centering process is all about making point-to-point sensing contact, it is possible to achieve high-precision positioning accuracy at the m level. In addition to this, the moving distance of the electrode during the process of separating the reference ball is reduced, the stroke of the machine tool is able to be utilized to its full potential, and the overall effectiveness of the process is enhanced.

2. Make sure to always use die casting services the same material for the electrodes.
Electrode material typically consists of red copper, which is used in the majority of domestic die-casting factories.Have you ever given any thought to the benefits that graphite electrodes bring to the table in the quest for high-efficiency processing in today's world?In point of fact, this comprehension is one-sided or still clings to the outdated concept of molding.

Die-casting factories are increasingly turning to graphite electrodes as a means of significantly reducing the length of time required for the production of die-casting molds in today's market.Because it can cut about half the amount of time needed for machining processes like milling electrodes or electric discharge machining.This is a significant benefit of graphite electrodes, which fully reflect the benefits of graphite materials. Graphite materials have a lot of advantages overall.Graphite processing is not appropriate for fine surface processing because this type of processing requires Ra0.4 micrometers or less.At this point in time, it is essential to decide between copper electrodes of high quality and copper electrodes.When performing electrical discharge machining on parts with a high value-added content, it is possible to achieve smaller electrode losses by using more expensive copper-tungsten alloys. This is especially true when processing carbide workpieces.The spark position of the electrode is made too small, which significantly lowers the level of efficiency achieved by the processing.
The majority of die-casting factories have transitioned from using conventional discharge machines to more advanced CNC discharge machines.Even though many factories have switched to using CNC discharge machines, the electrode spark position process still refers to the older style of discharge machine.15 millimeters on one face.On one side, the finishing electrode has a thickness of 0.06mm.Because of the small electrode spark position, the CNC discharge machine is severely constrained in its ability to use a larger current for high-speed machining.This is a method for carrying out a process that results in perfect effects in terms of the discharge surface, efficiency, and accuracy indicators.

4. The installation and adjustment of electrodes are still performed using a manual chuck.
Traditional manual chucks are utilized in die-casting factories in order to install and adjust electrodes. This may be due to the fact that these chucks are more robust or because they are more affordable.This technique is straightforward and useful, which contributes to its widespread adoption.In spite of the fact that they have invested hundreds of thousands of dollars in CNC discharge machines, some die-casting factories continue to use traditional chucks.The actual utilization rate of machine tools is not very high when they are equipped with conventional manual chucks.In point of fact, a good horse needs a good saddle, and the CNC machine ought to be outfitted with a 3R quick clamping and positioning fixture, which has the potential to eliminate the manual clocking process, reduce the frequent standby of the machine tool, and increase the production efficiency.

5. One variety of machining that frequently occurs involves die cast parts discharging the remaining tool R angle following the cutting process.
The occurrence of something called local electrode loss.

6. It is challenging to fulfill all of the requirements for high-finish processing on a large area.
If the electrical discharge machining (EDM) of die-casting molds in the die-casting factory are all large-area types and the surfaces are required to be below VDI18, a uniform spark texture is required, similar to a TV remote control type cavity.If this is the case, then electrical discharge machining is a pain.It frequently requires multiple rounds of trimming in order to achieve the desired texture, and the processing efficiency is also quite poor.Powder mixing processing technology should be considered if the job involves batch EDM processing of large-area and large-cavity molds. This technology has the potential to significantly improve the processing efficiency and make it much simpler to obtain large-area fine textures or mirror surfaces.Inaccurate control of the EDM surface's quality
In some die-casting factories, the requirements for the die-casting molds that are manufactured are not particularly high, and the discharge parts essentially need to be polished after they have been removed.In this particular scenario, mold electric discharge machining is striving to meet the requirements of VDI18 (Ra0.8m) or even mirror processing, but at the same time, it is complaining that the discharge speed is too slow and that the delivery time is too late.Electric discharge machining has the capability of reaching VDI22 (Ra1.25m) or higher for the vast majority of the processed parts that will need to be polished later.It is possible to process it more finely in order to avoid the polishing deformation when working with more delicate parts.What needs to be emphasized here is the fact that when high-quality matte surface requirements are pursued below VDI22, the discharge time will significantly increase, and the electrode loss will also increase. This is something that needs to be emphasized.
