Choose high-quality diamond wire drawing dies

At present, many domestic manufacturers are still using backward equipment to grind the pass. Therefore, there are the following problems: the pass parameters fluctuate greatly, and it is difficult to process a straight working cone; the sizing area and the work area are connected It is easy to grind the transition angle at the place, which causes the wire to produce secondary compression in the sizing area, increases the external friction, reduces the length of the sizing area, and shortens the service life of the mold; the frequency of repairing worn grinding needles varies from person to person. Irregular use results in poor hole pattern consistency. Detection methods are also backward, and can only rely on visual inspection or simple tools such as magnifying glass and microscope to detect. Moreover, it pays attention to the surface finish of the mold. It cannot effectively detect the hole size, let alone control it.

　　 The grinding process of foreign wire drawing dies generally uses high-speed mechanical grinding machines and diamond-plated metal grinding needles. The equipment runs smoothly. The specifications and standardization of the grinding needles make the product more accurate. The hole size of the mold is inspected with a profile recorder and an aperture measuring instrument, and the surface finish is inspected with a microscope dedicated to inspecting the drawing mold.
