At present, many domestic CNC machine tool operators are classified as follows: some operators are very familiar with mechanical processing, but are relatively unfamiliar with CNC machine tool programming, and some are newly graduated students who have no knowledge of mechanical processing and CNC. They are familiar with the theory of machining and programming, but …
In order to remove the blank from the die casting mold, the mold needs to be properly divided into several parts to facilitate demolding. The number of parting surfaces are: single parting surface, double parting surface and multiple parting surface. The shapes of the parting surface are: plane, inclined surface, stepped surface and curved surface. …

Sheet metal is a metal product processing technology, and there is no complete definition of sheet metal so far.According to the definition of foreign journals, sheet metal can be defined as a comprehensive cold working technique for thin metal sheets (usually less than 8 mm). These include cutting, stamping / cutting / compositing, folding, riveting, …
A few days ago, PTJ Engineering issued a document saying that it “processed CNC low-cost orders.” This will hurt yourself and your colleagues and customers! After reading, I was very impressed, and the industry has developed to this day. Do you have to fight hard for the unit price? There are more than 1 million …
First, the undercut knife method Outer convex processingAs shown in FIG. 1, when the outer opening is projected outward, the processing can be performed by using the “planar contour processing” method. Usually, the tool is selected from the outer point P1 (A’B’C’D’) of the blank material, so a vertical knife can be used and a …
