5. TSP  Diamond

Synthetic diamond polycrystalline is a kind of diamond polymer formed by sintering diamond and binder at high temperature and ultra-high pressure. Synthetic diamond polycrystalline has the characteristics of high wear resistance, high thermal stability and compact and uniform structure, and is widely used in the manufacture of petroleum, geological drill, diamond processing and mechanical processing tools. It is generally used as a guard diameter.

Shape: cube, cylinder, disc, rectangle, triangle, hemispherical, ellipse, etc.

6. wire drawing mold

Usually refers to a variety of metal wire drawing die, as well as pull fiber drawing die. All drawing dies have a hole in the center of a certain shape, round, square, octagonal or other special shape. Metal decreases in size and even changes shape as it is pulled through the die hole. A steel die is sufficient for drawing soft metals such as gold and silver. The die can have multiple holes of different sizes.

Use: wire-drawing die wide range of USES, such as electronics, radar, and TV, instruments and high precision wire and used in the aerospace and other commonly used tungsten, molybdenum wire, stainless steel wire, wire and cable wire and all kinds of alloy SiDou with diamond die is drawn out, diamond die as a result of natural diamond as the raw material, which has strong wear resistance, high service life.

Type of drawing mold

1, steel mold - pull soft metal (such as gold and silver) when the steel die is enough, the steel die can have a number of different aperture holes.

Tungsten Carbide Nib is generally used in the drawing of steel wire. The typical structure of this mold is a cylindrical (or slightly tonal) carbide die core closely embedded in a circular steel case. There are Bell radius (Bell radius), Entrance angel (Entrance angel), deformation (approach Angle), sizing belt (bearing) and exit Angle (back relief) in the inner hole of die core.

3, steel wire mold - pull non-ferrous metal wire, such as copper, aluminum, and more similar wire mold drawing die, some differences in the shape of the inner hole.

4, polycrystal mold - fine drawing line can be used to polycrystal mold (artificial diamond), and the use of natural diamond drawing mold.

    Applications of PCD grinding machine

    PCD grinding machine is a machine tool used for grinding Polycrystalline Diamond (PCD) cutting tools. PCD is a synthetic diamond product used in various cutting applications due to its exceptional hardness and wear resistance. PCD tools are commonly used in the machining of non-ferrous metals, wood, plastics, and composites.
