Polycrystalline diamond wire drawing dies for low efficiency, suitable for mass production

By grinding material on the grinding surface of the mold to complete the action of the processing hole. This method of polycrystalline diamond drawing die is less efficient, not suitable for mass production. Special processing is the direct use of  synthetic diamond , chemical energy, light and sound workpiece can be processed to achieve a certain shape and size and surface roughness, it does not require a hard tool material than the workpiece material, nor does it require significant abrasive grinding applied force. Although it is not conductive polycrystalline diamond itself, but its conductive binder, so you can use special processing method for processing. After  grinding wheel and process test, I use a combination of spark and ultrasonic methods to achieve a polycrystalline diamond drawing die from coarse to fine processing requirements. 2 polycrystalline diamond drawing die hole processing polycrystalline diamond wire drawing die hole structure, generally divided into the entrance area, lubrication zone, compression zone, sizing area, secure area, exit zone 6 parts.
