Why does the CNC bending machine adopt the forging method? With the development of society, my country's steelmaking technology has reached a certain level. At present, the common processing methods are mainly forging and casting. Castings are lower in cost than forgings. CNC bending machine molds are forged. Many people are curious about why not castings. This article will briefly describe the reasons. CNC Press brake Casting technology has a long history in my country. The overall cost of the workpiece is very low, mainly by smelting the metal into a liquid, and then pouring the liquid into a specific forming mold. After the metal liquid is cooled, a shaped casting is formed. The casting technology is to burn some steel material in a charcoal fire, and then quickly pull the red steel out and put it into an air hydraulic hammer for forging.
