PCD cutting tool blanks are manufactured through the sintering of micron diamond abrasives and hard alloys, as well as polycrystalline diamond abrasives and hard alloys, in environments of ultra-high temperature and ultra-high pressure. The hardness and wear resistance of this product are roughly the same as that of natural diamond, and its toughness is almost similar to that of hard alloys. It is ideal to use these materials for manufacturing long-lasting and high-efficiency tools. Polycrystalline diamond cutting blanks have different physical characteristics, making them suitable for special applications and capable of meeting various customer requirements.

PCBN blanks, designed specifically for cutting tools, are superhard materials made from a compound of polycrystalline CBN and hard alloys, sintered under ultra-high temperature and ultra-high pressure conditions. The hardness, wear resistance, and thermal stability of PCBN blanks are roughly the same as CBN, and their toughness is almost comparable to that of hard alloys. Due to their high hardness, they are ideal materials for machining cutting tools for ferrous and non-ferrous metals. PCBN blanks enable high-speed cutting and are suitable for continuous processing. When used for dry cutting, they operate quietly and are environmentally friendly. They are applicable for milling, boring, and reaming of materials with hardness HRC 45-65 (for example, cast iron, hard bearing steel, nickel and chromium alloys, etc.). So far, our company has been able to provide round, square, 80% rhombus, and triangular shapes.

PDC is produced through the sintering of diamond and WC using high-temperature and high-pressure technology. PDC "absorbs" the advantages of diamond and WC, possessing high wear resistance and excellent impact strength. It is applicable in the manufacturing of various types of drilling tools (for example: oil, geological, and engineering drilling bits, etc.). Our standard shape is round, but it is also possible to manufacture according to customer requirements.

In the same high-temperature and high-pressure environment, TSP has difficulty bonding with polycrystalline diamond and PCD products. TSP possesses wear resistance and thermal stability, and when temperatures reach 1200 degrees, the adhesive properties of TSP itself are inert, so the coefficient of TSP and diamond is the same. TSP is suitable for milling bits and oil drilling bits. Compared to natural diamonds, TSP is lower in cost and has a higher work rate.

PCD dice blanks are manufactured in high-temperature and high-pressure environments. Through the interconnection of high-quality diamonds, they achieve a higher hardness, and their wear resistance and thermal conductivity are roughly the same as natural diamonds, while their toughness is almost comparable to tungsten alloys. They are optimal as manufacturing materials for high-precision and long-lasting dies. Our PCD comes in two series: the BCD series and the TSP series.

Chromium has excellent wettability and affinity, so it forms chromium carbide on the surface of diamond abrasives through sintering. This chromium carbide enhances the retention of diamond abrasives and increases the bonding strength between the abrasives and the bond. Furthermore, the chromium coating improves the strength and corrosion resistance of the diamond abrasives.

Our company can provide two types of single crystal diamond plates. One is produced through a method called Chemical Vapor Deposition (CVD), and the other is produced through a method called High Pressure High Temperature (HPHT). Our single crystal diamonds are widely used in cutting tool applications such as inserts, end mills, and dies, as well as in dresser applications. Our products are primarily diamonds with a crystal orientation of 100, but we can also provide single crystal diamonds SCD-WD (with a crystal orientation of 111) for die applications.
