Instead of focusing on how to do a good job and make it perfect, it constantly breaks through the bottom line and makes people feel even more disgusted:
Some black-hearted "upscale" mahogany furniture, even the so-called "counterfeit and inferior products" can not be called, is exactly a pile of pieces of white skin and scrap pieces together. The ordinary consumers of these shoddy products are difficult to discern, and their selling prices are lower than that of formal mahogany furniture. This is a naked fraud rather than deception!
All of these are "old craftsmanship", and it is not new to senior woods. In the same period, we got some of his photographs from a master craftsman. It was amazing!
From the map point of view, this board looks very ordinary, quite satisfactory.
In fact, it is the core material like this!
Because of the overlap of some furniture borders, after the "ingenious" layout and workmanship, the finished product generally does not show any flaws after appearance. After the destruction, its "black heart" party reveals no doubt!
The following is a picture of a customer wearing a set of Vietnam Pear Palace chairs bought in a place. It's really shocking!
Mirror EDM, mirror EDM is mainly used in the precision machining of complex mold cavity, especially the complex curved surface which is not convenient for polishing. It can save the manual polishing process, improve the performance of parts, and shorten the mold manufacturing cycle. Very important practical significance.
After the conductive fine powder enters the discharge gap, it is equivalent to inserting multiple small conductors between the two poles, and also distorts the electric field in the discharge gap, which reduces the resistance to breakdown of the insulating medium in the gap, and discharge easily occurs, and the discharge gap increases accordingly. . The increased discharge gap reduces the initiation effect of the electric corrosion products on the discharge, and is conducive to the flow and discharge of the electric corrosion products, thereby reducing the occurrence of concentrated discharge and making the discharge evenly distributed on the processing surface. The discharge gap increases and the discharge channel becomes thicker. Under the same discharge pulse energy, the heated area of the workpiece surface increases and the heated intensity decreases, thereby forming large and shallow discharge pits on the surface of the workpiece. At the same time, the increase of the discharge gap also reduces the discharge ability of the molten metal to the discharge, allowing more molten metal to re-solidify on the surface of the workpiece, further reducing the depth of the discharge pit. Therefore, powder-mixed EDM forms large and shallow discharge pits on the surface of the workpiece.
Powder mixed Electrical Discharge Machining forms large and shallow discharge pits on the surface of the workpiece and the uniform distribution of discharge pits is the fundamental reason for reducing the roughness of the processed surface
